Exchange 2016 CU9 DAG 2 Nodes
Windows 2016 Data Center
Today I woke up and all my Outlook clients are disconnected from my Exchange 2016 Servers.
Restarting the clients did not help
starting outlook in safe mode did not help either
I can access the accounts via OWA
Hope I can resolve this before everyone gets in today
What can I look for?
Thank you in advance
