Attachment size exceeds the allowed outlook limit. Sending large files using Outlook. Changing the Limit on Your Email Account MS Server mail
Quite often, in the course of work, corporate users need to send large attachments through an email client, and they may face an error sending a letter.
Outlook
The thing is that in mail client Outlook (including in versions 2010/2013/2016) exists limitation on maximum size attachments to the letter - 20 MB. Moreover, it does not matter whether one large file is attached to the letter or several small ones - the limit on the total size of attachments will always be 20 MB.
When trying to send an email larger than 20 MB in Outlook, an error window appears - The attachment size exceeds the allowable(attachment size exceeds the allowed limit):
In the event that your mail server and the recipient's server supports larger mail sizes, the attachment size limit in Outlook can be increased.
You can change the maximum attachment size limit in Outlook only through the registry; there is no such setting in the Outlook GUI.
Procedure
After the changes have been made to the letter in Outlook, you can attach an attachment larger than 20 MB (in our example, we attached a pst file of 58 MB to the letter).
In the event that your mail server or the sender's server does not support large letters, when you send a large letter, you will receive an NDR-Non delivery report, which will indicate that the maximum message size has been exceeded. Below are the popular options for the text of such a bumper:
- Attachment size exceeds the allowable limit
- 552: Message size exceeds maximum permitted
- System Undeliverable, message size exceeds outgoing message size limit
- The message was not sent; reduce the message size and try again
MS Exchange
In Exchange, you can change allowable size letters at three different levels:
- In the transport settings of the Exchange organization
- In the parameters of the sending / receiving connectors
- In the settings of a specific user's mailbox
The current limits can be viewed through the Exchange Management Console (EMC), but it's much easier and faster to use PowerShell. In the Exchange Management Shell console, or after connecting to Office 365 via a remote PowerShell session, run the commands:
Get-transportconfig | ft maxsendsize, maxreceivesize get-receiveconnector | ft name, maxmessagesize get-sendconnector | ft name, maxmessagesize get-mailbox administrator | ft Name, Maxsendsize, maxreceivesize
The commands should return something like the following, containing the current limit settings:
- In the transport parameters of the entire organization, the size indicates that the received / sent message should not be more than 25 MB
- All connectors have a 10 mb limit
- For the administrator mailbox, the limit on the size of letters is not set (unlimited)
Naturally, the last command checks the limits for only one mailbox. You can deduce the limits on the size of letters for all users of the organization as follows:
Get-mailbox | ft Name, Maxsendsize, maxreceivesize
To increase the maximum message size (both received and sent) accepted by the Exchange Transport service from 25 MB to 100 MB, run the command:
Set-TransportConfig -MaxSendSize 100MB -MaxReceiveSize 100MB
The syntax of the command to change the limit on the size of letters for connectors is the same, but the change command will have to be executed for each connector.
Set-SendConnector "Connector1" - MaxMessageSize 100Mb Set-ReceiveConnector "DefaultConnector1" -MaxmessageSize 100MB
Or for all connectors:
Get-SendConnector | Set-SendConnector -MaxmessageSize 100MB Get-ReceiveConnector | Set-ReceiveConnector -MaxmessageSize 100MB
Similarly, you can change the limit for all mailboxes in the organization:
Get-Mailbox | Set-Mailbox -MaxSendSize 100MB -MaxReceiveSize 100MB
Limits set in this way limit the maximum message size, regardless of whether it contains an attachment or not.
Using the web interface
There is another option - through the web interface. Open the Exchange admin center and go to the section mail flow -> send connectors -> organization transport options:
and set the required maximum investment. Please note that when sending to an external server, the attachment is encoded in the MIME64 format, which increases the total volume of the letter by about 30%.
In the mail client Outlook (including the latest 2010/2013 versions) there is limit on the maximum size of an attachment to the letter - 20 MB. Moreover, it does not matter whether one large file is attached to the letter or several small ones - the limit on the total size of attachments will always be 20 MB.
When trying to send an email larger than 20 MB in Outlook, a window appears with an error:
The attachment size exceeds the allowable
Attachment size exceeds the allowed limit
In the event that your mail server and the recipient's server support a larger size of mail messages, you can increase the attachment size limit in Outlook.
You can change the maximum attachment size limit in Outlook only through the registry; there is no such setting in the Outlook GUI.
After the changes have been made to the letter in Outlook, you can attach an attachment larger than 20 MB (in our example, we attached a pst file of 58 MB to the letter).
In the event that your mail server or the sender's server does not support large letters, when you send a large letter, you will receive bump stop(NDR-Non delivery report), which will indicate that the maximum message size has been exceeded. Below are the popular options for the text of such a bump stop:
- Attachment size exceeds the allowable limit
- 552: Message size exceeds maximum permitted
- System Undeliverable, message size exceeds outgoing message size limit
- The message was not sent; reduce the message size and try again
Exchange 2010 sets the maximum message size. The following table lists the maximum email size limits for popular email services.
You’ll receive an error message if you attempt to attach files larger than the maximum size limit. There are a few ways to work around this size limit, including using a file sharing service or compressing the file.
Outlook limits the size of files you can send. This limit prevents your computer from continually trying to upload very large attachments that exceed the limits of most Internet service providers. For Internet email account. such as Outlook.com or Gmail, the combined file size limit is 20 megabytes (MB) and for Exchange accounts (business email), the default combined file size limit is 10 MB.
Save your file to a cloud service and share a link
There are many cloud storage services to which you can upload and then share large files. Some popular cloud storage services include OneDrive, Dropbox, iCloud, and Google drive... Once your file is stored in the cloud, you can include a link to the document in your email message.
Upload your file to a cloud service, such as OneDrive or Dropbox.
Note: The service you use generates a link to access your file. Your recipient can open the link to download your file.
After you upload the file, copy the link, and paste it into your email message.
Compress the file
When you compress, or zip, your file, it decreases its size, and it might decrease it enough to fit within the Outlook size limits for attachments. The following articles describe how to compress and extract files for different Windows operating systems.
Reduce the size of an image
If you're sending large image files you can automatically resize them to reduce their file size.
Save the file to a SharePoint server library
If you're using Outlook in a business environment and use SharePoint, you can save a file to a SharePoint library and share a link to the file. See Share a document using SharePoint or OneDrive for instructions.
For Outlook 2010 and Outlook 2007, if you try to send a message with attachments that are too large, the message “ The attachment size exceeds the allowable limit”Appears.
Issues with large attachments
Even if your message doesn’t exceed the Outlook or Exchange Server attachment size limits, there is a chance your recipient’s email provider might block messages that include large attachments. To help reduce the size of attachments that you send in Outlook, see.
In addition to mail provider limits on total message size, sending large attachments through email is not always the best solution.
Your message might cause your recipients' mailbox to exceed the storage quota If the recipients ’mailboxes exceed the storage quota, the recipients could be prevented from receiving other messages.
Your message might cause your mailbox to exceed the storage quota Each message that you send is saved in the Sent Items folder. Sending large attachments to other people counts against your mailbox size quota as well. When you exceed the storage quota, you could be blocked from receiving additional messages.
Attachment bloat When a file is attached to message, it has to be encoded. The encoding process causes attached files to become 1.37 times larger than they are on your computer. For example, if you send a 5 MB file attachment, the attachment is sent as 6.85 MB of data.
Efficiently share large files
There are several ways to share large files and collaborate with other people without sending attachments.
Microsoft SharePoint Server libraries If you have access to a SharePoint Server library, files can be saved to the library. For more information, see Save a file to a SharePoint library. SharePoint libraries can be accessed directly in Outlook.
If your organization uses SharePoint Server and provides you with a My Site, you can upload your files to your My Site Shared Documents library, and then include a link to the file in your message.
When you open the SharePoint document library to which you have uploaded your file, right-click the link to the document, click Copy Shortcut, and then paste (CTRL + V) the shortcut into your message.
OneDrive OneDrive is a free Microsoft service that provides password-protected online file storage making it possible to save, access, and share files online with friends or co-workers, from nearly anywhere. You can save Microsoft Office documents directly to OneDrive. For more information see, Introduction to OneDrive.
Shared network locations Save files in a folder that your recipients can also access. You can then send recipients a message containing a link to the shared location. On the Insert tab, in the Links group, click Hyperlink... If the shared location path or file name contains spaces, see Add links containing spaces to an e-mail message.
Photo sharing sites If you are sending pictures to someone, consider resizing those pictures before you send them. See Reduce the size of pictures and attachments. With modern digital cameras, each picture can be 3 MB or more when you transfer them from your camera. If you don’t want to resize your pictures, there are many photo sharing websites where you can upload your pictures, and then send a link to the pictures in a message.
Video sharing sites Even a short video file can be very large. Consider sharing video clips using one of the methods described in this article or to a video sharing website.
Security Note: When you attach a file to a message, you determine the intended recipient. If you upload a file to a shared location or service, make sure that you understand the privacy and security settings of that site, including who has access to your file.

You can edit the Web.config file on the Client Access server to enable the large email sending feature using Outlook Web App. Outlook Web App is an application that uses the ASP.NET service and depends on the ASP.NET settings configuration.
The ASP.NET service setting that determines the maximum amount of data that a browser can send to a Client Access server is maxRequestLength... Parameter maxRequestLength is located in the Web.config file. If the parameter value for the maximum message sent to the mailbox exceeds the parameter value maxRequestLength messages sent from Outlook Web App that are larger than maxRequestLength, may result in an error. To avoid this, you need to configure the parameter maxRequestLength so that it has at least the same value as the maximum message send size for mailboxes in the organization.
Conditions and related warnings
When a user tries to create or send a message that exceeds the maximum message size or value maxRequestLength, Outlook Web App displays a warning. The text of the warning depends on the conditions for its creation.
- When a user tries to download an attachment that exceeds the maximum message size, the download dialog displays the following error message: "Attachment exceeds the maximum allowed attachment size."
- When a user tries to download one or more attachments that exceed the parameter value MaxRequestLength ASP.NET Service, the Information Bar displays the following error message: "Files<filenames> not invested, since they exceed the investment limit equal to<limit_size> (MB) ".
- If the user is attaching multiple files, each of which is less than the maximum message size or parameter value maxRequestLength, but their total volume exceeds the maximum message size, then when the button is pressed send Outlook Web App displays the following message as a header on the message form: "This message could not be sent because it exceeds the maximum size allowed."
- By default, the size limit for a single attachment is 10 MB.

Using Notepad to Change the MaxRequestLength Value
The entry " Text editor»In the Client Access Permissions section.
- On the Client Access server, locate the Outlook Web App Web.config file. By default, this file is located in the folder<disk> \ Program Files \ Microsoft \ Exchange Server \ V14 \ ClientAccess \ Owa.
- Make backup of this file.
- Open the source file with an editor such as Notepad. Don't use a manager Internet Information Services to modify the Web.config file.
- Find the parameter maxRequestLength and change its value. The value is stored in kilobytes (KB). The default is 35000. The following example shows the value of the parameter maxRequestLength in the Web.config file.

Good afternoon, dear readers and blog subscribers, not so long ago we were considering changing the id teamviewer 11, today we will analyze another outlook 2007 and higher error and it sounds like this "The maximum allowable message store size has been reached." The symptoms of the problem are, you try to get new mail, the process begins. It detects that there are fresh letters and starts receiving them, but after a couple of seconds, it reports that there are problems and you need to perform a series of actions. Let's figure out what's the matter.
This is how error 0x5004060C looks like. You are immediately hinted that you need to reduce the amount of data in the message store by highlighting and deleting unnecessary messages using the Shift + Del combination. But you must admit that for an ordinary user, the question arises what kind of storage it is.
If you close this window, then you may be offered to clean up your mailbox, and then everything starts to take shape in its own way, the storage means your outlook profile, this is either a pst and ost file.
The mailbox size limit has been exceeded. Specify messages to delete and move, empty the Deleted Items folder, or move messages to archive.
You have two options here:
- Perform cleaning deleted messages, this is done with one button, but sometimes this may not be enough, since there may be no letters.
- Archive the mailbox, here you select either by size or by the date of receipt of the letter and start creating an archive. Archiving will create a separate pst file in which all letters will be placed according to a certain criterion, this process is not fast and depends on your hard disk and the number of letters.
The maximum size of the ost and pst file in 2007 is 20 GB, outlook simply will not be able to work normally with large volumes
If deleting does not give a special effect, then I advise you to compress in outlook,
Default mail storage size
Let me now show in parrots what sizes are the default for ost and pst files. There are two types of records:
- Unicode files - MaxLargeFileSize and WarnLargeFileSize
- ANSI files (old format) - MaxFileSize and WarnFileSize
For Outlook 2003 - 2007
For Outlook 2010 - 2016
You can see the paths to the registry keys just below:
- Outlook 2003 HKEY_CURRENT_USER \ Software \ Policies \ Microsoft \ Office \ 11.0 \ Outlook \ PST HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 11.0 \ Outlook \ PST
- Outlook 2007 HKEY_CURRENT_USER \ Software \ Policies \ Microsoft \ Office \ 12.0 \ Outlook \ PST HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 12.0 \ Outlook \ PST
- Outlook 2010 HKEY_CURRENT_USER \ Software \ Policies \ Microsoft \ Office \ 14.0 \ Outlook \ PST HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 14.0 \ Outlook \ PST
- Outlook 2013 HKEY_CURRENT_USER \ Software \ Policies \ Microsoft \ Office \ 15.0 \ Outlook \ PST HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 15.0 \ Outlook \ PST
- Outlook 2016 HKEY_CURRENT_USER \ Software \ Policies \ Microsoft \ Office \ 16.0 \ Outlook \ PST HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 16.0 \ Outlook \ PST
Now, by editing the necessary registry keys, you will eliminate the error "The maximum allowed size of the message store has been reached." I honestly do not imagine profiles that will be over 50 GB in size, this is how many letters and what they should be there is not comprehensible to my mind. If you know other methods for solving this problem, then write about them in the comments under the video or article.
