I had an email account set up in Outlook for mac 2011. I had all my emails in the account, plus around 500 contacts, all my calendar dates in outlook and all of a sudden it is all deleted. I go to my outlook and it's like I never set up an account or added contacts. It has gone back to before I added an account, contacts or calendar. Am I really going to have to enter my account, contacts, and calendar all over again? What a hassle!
