Exchange 2016 ECP Mailbox details error 500

Hello,

We upgraded recently our Exchange 2016 servers from CU19 to CU20.
When we are trying to allow a mobile device via ECP 'Recipient' 'View Details', we are having an error 500, and sometime a 'HttpException (0x80004005): Request timed out'.
But it does not occur for all users, I tested around 10 users, and I'm facing the issue for only 1. I thought that mayb this user is having too many devices allowed (15), so the request is taking time, and end failing.
When I try via Exchange management shell (get-MobileDeviceStatistic), it is responding, but it's very slow.

Any idea why please?

Thank you in advance.

Regards,

    Hi @Chriskw29

    Please try increasing timeout for ECP to resolve your issue above.

    PLease Launch Command Prompt using Elevated Mode and ran the following commands:

    C:\windows\system32\Inetsrv\
    Appcmd add backup "BackupTimeOut"
    Appcmd set config "Default Web Site/ecp" -section:httpRuntime -executionTimeout:2400
    Appcmd set config "Exchange Back End/ecp" -section:httpRuntime -executionTimeout:2400

    If that does not work your server is most likely overloaded and needs to have more resources allocated to the VM.
