Application Event 27 MAPISendMail error and sending attachment outside of Outlook fails

Applies to: Outlook 2013Microsoft Outlook 2010


You attempt to send a file as an attachment from a program other than Microsoft Outlook (for example, Microsoft Word), and nothing happens.

In reviewing the Application Event log, you find an error for Outlook with Event ID 27 containing the following error text:

MAPISendMail: Failed to submit message. Attachments to the message exceeded the size limit set by your Administrator

This event log entry is shown in the following figure:


This error will appear in the Application Event log if you have attempted to send an email attachment which is over the size limit established in your Microsoft Exchange environment, and the attempt was made outside of Outlook. An example of this would be when you right click a file and select Send To and select Mail Recipient.

If the selected file is over the attachment size limit and Outlook is not running, you may be prompted for an Outlook profile if Prompt for a profile to be used is selected in the Mail Control Panel; however, a new message in which to send the attachment will not appear.


There may be several options to prevent the Event ID 27, and successfully deliver the attachment.
  • Reduce the size of the attachment if possible; for example, lower the attachment size by adding it to a compressed (ZIP) folder.
  • Place the file on a share or web host accessible by the intended recipient, and send a link to the file via email instead.
  • Request that your Exchange administrator increase the allowable limit for email attachments.
