Word 2010 and Outlook 2010 (Windows 7) - Error Message : "Word couldn't send mail because of MAPI failure unspecified error"
Posted on 2014-09-17
In my environment we have Office 2010 on Windows 7. Since moving to Office 2010 (we did fresh OS installs when we upgraded) I'm seeing the following error on a lot of my user's systems when they try to use the "Send As Attachment" QAT button from within Word 2010.
"Word couldn't send mail because of MAPI failure unspecified error"
Here is the strange part. The FIRST time you use the "Send As Attachment" button, it works flawlessly, creating a new email in Outlook 2010 and putting your Word document in as an attachment. You can send the mail off and not think about it again. However, if you attempt to use the "send as attachment" button a second time, either for the same document OR a different document, that is when Word kicks out the MAPI failure error listed above. This happens each and every time from within Word that a user tries to send a document as an attachment a SECOND time in the same session. If you close Word and Outlook, and reopen both, the session resets and you can send ONE attachment again.
This is killing productivity. I have been all over the web and seen everything tried to fix this, and came up short. Most people seem to have the problem right away and all the time, unlike my people who can get one email off before the problem forces them to close down. I've tried updating Office, I've tried completely uninstalling Office and reinstalling, I've tried removing my third-party add-ins (we have a metadata scrubber in Outlook), nothing works. What could be causing Word and Outlook to lose their MAPI connection to one another just by creating/sending an email?
Any advice would be appreciated. I've pretty much exhausted all my ideas thus far.
