Last week, a colleague that's been using Outlook for Mac 2011 for the past three years began having major issues. When she started Outlook, it would indicate in the Dock that it was open, but there would be no window. Using the menu at the top of the screen, she could eventually open the window, but it wasn't responsive and it didn't have any content. The whole time, she could access Preferences and even open the New Message and other windows just fine. But she could not see any messages or navigate the Main Window.

We tried several reported solutions including deleting all preference files and even the Identities folder. We rebuilt the database several times, added a fresh identity and made it default, tried rebooting the computer, and even uninstalled Office and reinstalled it from the disc. Nothing worked, so eventually she decided to use Parallels and run the Windows version of Outlook.

Now, another colleague has the EXACT same problem. He's a new employee, so his was a very recent install of Office. Both are completely up-to-date at 14.4.4. They each run a different version of Mac OS X, though:  one is 10.9.5 and the other is 10.7.5. I run OS X 10.9.5 and Office 14.4.4 -- mine is, so far, running just fine (fingers crossed, knocking on wood, etc.!).

Any help would be greatly appreciated as the problem seems to be spreading toward my part of the office!    =)
