I am running Outlook 2011 on Yosemite/10.10.3 with all the latest updates installed.
When I try to add an Exchange account to Outlook, it initially runs the sync just fine. However, for any subsequent requests, I keep getting an error saying that my username or password is incorrect. If I re-enter the password, the sync works again... till the very next sync. So, the credentials I'm entering are correct
The Mail.app is able to connect to this Exchange account with my credentials. I can verify that my account is not locked out since my other devices are able to sync.
So far, I've removed the Keychain entries for my Exchange and Mail.app for the same account and deleted/added the same account multiple times to the system. I've verified and repaired Keychain as well.
I'm stumped and can't figure out why this is happening.
Any help would be appreciated. Thanks!
