Microsoft Outlook 2011 constantly crashing I just purchased Microsoft Office 2011 for Mac last week. Outlook CONSTANTLY crashes. I have tried everything… uninstall and re install twice, rebuilding main identity. Please help! I am so frustrated since I just purchased this. I am running Mountain Lion as well. 

Here is the error when it crashes:

From the crashlog it looks like Merp is causing the crash.  I googled merp crashing outlook and came across an article on answers.microsoft.com.  From what it said, you need to update Microsoft Error Reporting Program (Merp) from Here:   http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&amp;id=28734.

Before you do that, check and see if you have any rules that may be corrupt and remove them.

Here's the link about Merp crashing outlook:
