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,
