Windows 10: Outlook 2016 with Exchange/Domains

I'm not sure if a recent update to Outlook 2016 (I subscribe to Office 365) introduced this or not...

Recently, I'm frequently prompted for my password for an email where I'm an independent contractor.

If I set the account up as new, it goes through fine. Periodically while the laptop (Windows 10) and Outlook are on, all of my devices will start requesting me to enter a password and they go offline. The Exchange server, which uses a domain ("ps") will lock me out for a few hours.

If my laptop is shut down or Outlook is not running, this does not occur. Another Exchange account does not have the same problem.

Has anyone else had problems with this? Is there a special setting I need to enable two Exchange accounts?

Outlook 2016, the Mail App, and Windows Server 2003

Outlook 2016 is not compatible with Exchange Server 2003 if thats what you are using. But you should still be able to join a Windows Server 2003 Domain.

 

Microsoft Exchange Shared Calender no showing up.

I have a Microsoft Lumia 950XL and I am attempting to view a Microsoft Exchange calendar that has been shared with me from a Rackspace Hosted Microsoft Exchange server. My email account is also an exchange email account on the same domain. The shared calendar
shows up no problem on the desktop versions of outlook 2013 and 2016 and also in Outlook web access. I can't see an option on my mobile to view the shared calendar. Please could someone point me in the right direction or is it not possible to view a shared
calendar without entering the owners credentials and setting up the owners account on the phone?

 

I think I may have figured it out. The Windows Mail client was configured for the Exchange account and likely had an outdated password. I deleted the account from Mail and hope this will resolve the issue.

 

I experienced a similar issue with Office/Outlook 2016,
Now I use T-Bird, does the job, however I still prefer Outlook, especially in a work/production environment.
So problem resolved?
I'm getting that I want office back feeling, .......
