Outlook 2011 mac does not remember passwords
There could be diferent causesand solutions to this problem but this solution worked for me:
1. Shut down all applications.
2. Open Applications/utilities Keychain access.
3. In the keychain menu choose keychain repair and execute it.
4. Restart your computer.
5. Start outlook. It will probably still need the missing password, remember to cross the "save" .
If not the problem is solved and you can stop here.
6. Restart you computer.
7. Start Outlook. Now it should be fixed!
