We’ve seen some strange ‘attach file’ behaviour in Outlook 2016 installed via Office 365 ProPlus.
Specifically, when you click on the Attach File icon, the dropdown menu of Recent Items and other locations disappears, rolling back up. You can’t actually attach a file.
This behaviour appears when Outlook updates the Recent Items list.
It does not happen for all users. Love those random problems.
The workaround is:
- Click on File, Office Account
- Click Sign out under your User Information.
- Restart Outlook.
- Sign In again
Sadly, the Microsoft Community forums are full of posts and replies form people saying ‘me too’. http://answers.microsoft.com/en-us/office/forum/office_2016-outlook/outlook-2016-disappearing-attach-file-menu/717b604f-3c31-4c4f-990e-50501e0e8b50
I saw one Microsoft response saying they were aware of the problem, but can’t find anything official to say it’s been recorded as a bug or if they are working on a fix.
