I installed Windows 10 Pro with Office 2016 Home & Business.
Everything works fine with Outlook 2016 connecting to our Exchange 2010 Enterprise. The connection is quick, the sync is fast and the data is always up-to-date.
Then after doing all my tests, I was ready to join my PC to our Windows 2008 R2 domain.
When I join the domain, it creates a new profile (this is normal), where I have to configure most of the programs again.
When I get to Outlook 2016, it does validate the email account fine.
Now everytime I start Outlook 2016 (after being already configured with my email account), the initial connection to the server takes between 2-3 minutes (as opposed to 5 seconds when it was a standalone) and syncing takes very long.
Is there a way to determine what is happening?
As I said, as soon as I join our domain, the behavior of Outlook 2016 goes to pieces.
I need a solution before I start upgrading our 30+ remaining users to Outlook 2016.
Thanks for your help,
