All Outlook clients failing to connect to Exchange 2016

Exchange 2016 CU9 DAG 2 Nodes
Windows 2016 Data Center
Outlook 2013/2016

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?

Any commands?

Thank you in advance

I guess you already checked database mount status.
Have checked whether you have any DNS issue?
Also outlook connectivity?
