I am using an iMac with Outlook 2011 installed. Until last week, there was no issue. Now, when I open Outlook, it initializes but does not open.
I tried rebuilding the database, twice. After Googling, I found instructions to delete com.Microsoft.outlook.plist file, restart the system and test if it works.
I did so, and now every time I want to use outlook. I need to delete the same file to open outlook.
I tried to re-install office 2011, without success.

This is a known issue with the latest 14.5.0 update:

I suggest you update to 14.5.1 which contains a fix for this problem:
