Hello, I am trying to configure content in O365 Exchange App.
A soon as I click on Content tab this error pops up:

I can browse my mailboxes, even select them, and click on Save button in the configuration window. But then it throws up an error and nothing happens.
There is a SQL error in AdMailboxMonitor.log:

I tried with two CommCells and using different O365 accounts. Same problems every time.
Since it worked before I suspect it has to be something wrong with 11.26.17.
Anyone here able to confirm this?
Configuration of SHP, Teams, and OneDrive goes smoothly.
Thank you!
