Hello,
after migrating our over 19.000 mailboxes to Exchange 2019 we get tons of the following error in the Application log of the Exchange server, which is hosting the mailbox databases:
"DateTime values that are greater than DateTime.MaxValue or smaller than DateTime.MinValue when converted to UTC cannot be serialized to JSON."
Is there a way to suppress this error?
Thanks
Jörg

Which CU are you using? Update your server to CU6 and make sure Windows server has installed all patches.
It seems a bug with migrated Exchange servers, try recycling OWA app pool and rebooting your server, see if OWA gets working.

Exchange 2019 CU6.
On a test system Exchange 2019 CU7.
On both systems we see the error.
Reboot doesn't help. Recycle app pool doesn't help.
Someone suggests it's the time zone configuration. We use UTC+1 as time zone, as you can see here

Greetings

Jörg,
Which Windows Server 2019 edition is in use? Windows Server 2019 Standard or Windows Server 2019 Core?
Are there any other software components installed besides Exchange Server 2019?
-Thomas
We use Windows Server 2019 Standard.
Only Exchange 2019 is installed besides a Microsoft SCOM agent.
Greetings
Jörg
For all who interested: The bug stays in Exchange 2019 CU7.
Greetings
Jörgs
I would open a support ticket with Microsoft.
I would like to, but we have no support contract.
Greetings
Jörg
