Exchange Server 2019 mailbox error
On Exchange 2019 when I login to my mailbox. When I try to open any email I get this error:
Then after i get this error:
I have tried a new throttling policy with the OwaMaxConcurrently. I have just uploaded a new SSL a couple of days ago so don't know if this is the issue?
Any help would be much appreciated.
- You can try to add more users session inside the MS Exchange IS registry key.

By default Microsoft Exchange limits the number of sessions a user can have open to 32.Thierry Chapuisat I cannot find MsExchangeIS in Windows server 2019 I don't know if this is different because the article is for Exchange 2016 where as I'm using 19?
- The MsExchangeIS is in this key : Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS
