Outlook 2011 for Mac Misbehavior

Recently I upgraded my work computer from Mac OS X Lion to Mountain Lion. I also updated all the MS Office apps. Everything seemed to go off without a hitch as I experienced no issues during the upgrade and all the apps I use on a daily basis haven't seemed to experience any issues... until this week.

As much as I really, really dislike the Microsoft Office products and especially Outlook, I have to use them for my work on a daily basis. Suddenly just this week Outlook began misbehaving by no longer allowing me to search for messages. Any attempt to search my inbox resulted in nothing. This quickly became a pretty big problem because the inability to search made me realize how often I rely upon this feature every day.

Upon doing some research, I found many others with this same issue, but I couldn't find a definitive solution. Digging deeper, I discovered that Outlook relies upon Spotlight to perform searches. So the solution was to reindex the messages in my inbox, right? I tried forcing this by dragging and dropping the MS Office Identities directory into the Spotlight preferences' Privacy tab and then removing it. No dice. Then I tried to simply reindex everything using mdutil:

$ sudo mdutil -i on /
Spotlight server is disabled.

Hmm, I guess I need to enable the Spotlight server:

$ sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

Then I was able to run:

$ sudo mdutil -i on /
/:
 Indexing enabled. 
$ sudo mdutil -E /
/:
 Indexing enabled. 

This seemed to trigger some indexing, but nothing notable appeared in the Spotlight menu (cmd-space) like I've seen before when the drive is being reindexed. So the last thing I tried was to determine if there is a plist file for Spotlight. My guess was that the plist file had to become corrupted. In similar cases (I had to do this recently for the screensaver) when a plist file becomes corrupted you have to remove it and let it be recreated. So I found a plist file for Spotlight and removed it:

$ rm ~/Library/Preferences/com.apple.spotlight.plist

After rebooting the computer, I could see the reindexing immediately kick off via the Spotlight menu. After waiting three or four hours for the drive to be indexed, I can again search the inbox in Outlook. Yay!
