I've been experiencing a very frustrating crash issue with Outlook 2011 over the past few weeks. Essentially, whenever I'm creating or replying to an e-mail and I hover over a contact in the To: or cc: fields, Outlook will crash. 

I've tried to re-build my database but the problem does not go away. Through some trial and error, I think I've narrowed the problem down to the contacts as I created a new identity with just my contacts and I get the same crash problem. 

However, what I'm now stuck on is how to remove this issue from my main identity. I have attempted to simply delete my contacts but this has no impact. 

Has anybody else experienced a similar issue and if so, did you manage to resolve the issue?

Thanks
