My problem is with Outlook 2011 for Mac being unable to maintain a persistent connection with Office 365 Exchange.
I have two separate Macs and both experience the same problem.
When I launch Outlook it automatically connects to the Office 365 servers, syncs and remains connected for a few minutes.
Then an interrupt appears and requests a password.
When I type in the password it is rejected. I have tried countless times and always with the same result.
I can use the Office 365 portal and OWA just fine.
I can use my Windows 7 machine, my iPad, and my iPhone --- all with no problem.
The Outlook 2011 DOES actually connect for a few minutes.
The connect time varies from a minute or so to about 10 minutes.
The behavior is not connection dependent. I get the same result wired or wireless and from multiple locations.
I did NOT have this problem for the years I used the same Outlook setup with Apptix — but they were running Exchange 2007.
I use the same Outlook 2011 connect another email account to Apptix's 2007 Exchange server and I experience no connectivity problems.
I have searched MSFT HELP and scoured the Internet. It seems there are many connectivity issues around Office 365.
The system DOES connect so we know the credentials ARE correct.
Note that I use another Outlook email account that successfully maintains a persistent connection to Apptix's Exchange 2007 server.
Note that Windows 7 machines, iPads, iPhones, and OWA all successfully connect and remain connected.
Note that the other email account using Apptix hosted Exchange DOES maintain its connectivity.
