After installing Outlook 2016 (on both Mac El Capitan and Windows 7/8/10), I was able to use Outlook ok... until I wanted to change my password. In previous versions, Outlook failed the authentication, asked me to re-enter my credentials, and from that point on, it used the new credentials. This is no longer the case. For the last 2 or 3 updates to Outlook (including 15.36, the most current) , it consistently fails to authenticate, supplying old or incorrect information and not correctly updating whatever local password cache it uses.
I've already tried removing the credential manager/keychain manager entries, deleting and readding the account, reinstalling the software, and modifying the credential format specified, all to no avail. Every time I start Outlook, I get prompted for password. This is local Exchange 2016 server; no federated id, office 365, no cloudy stuff.
I'm about at the end of my rope here - all the bogus authentication attempts cause our breakin detection sw to trigger, resulting in having to re-enable my mailbox multiple times a day.
Is there a tool that reliably fully eliminates all stored password information for Outlook so I can enter the correct info, or how do I get this to work beyond a single session? The password change appears to have precipitated the problem -- and now I can't seem to shake it. I know the password is correct.
It's reached the point of users refusing to use Outlook in favor of Apple Mail or Windows Mail. Help?
