I have recently upgraded to mountain lion on my macbook pro. The install went fine but ever since i have upgraded MS oulook does not work properly. I am able to receive emails but am unable to compose new or reply (the window does not open). I am up to date, have tried reinstalling safari and microsoft office and updated and enabled fonts (stuff suggested elsewhere). I can also not open any links in a MS word document. After doing a bit of troubleshooting it seems the error doesnt occur after booting in safe mode. I went to User accounts under system preferences to check for login items that might be affecting but to my surprise there are none so it seems i am back to squre one. It is puzzling me why it isnt happening in safe mode. Anyone have any ideas? would posting a list of all background tasks running normally and then again in safe mode be of any help to see if anything is interfering or is it something else? Will be very grateful for any help provided. I use outlook heavily for work and am lost without it.
