Some Mac users have updated from Outlook 2011 to 2016 and now are having troubles connecting to an on premise Exchange server with their credentials. The error is "Authentication failed. Check your information". Users get prompted twice to "Allow the autodiscover", but allowing it doesn't make Outlook work anyway.
Seems a majority says Outlook 2016 supports Exchange 2010 and up. Which one, the v14.0? There was only one blog that said minimum requirement is 2010 SP2. Does anyone know the specific minimum version supported?
