Answer 1

Hi @GCE ,

I would suggest you try to disable MRS proxy and enable it again:

Get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -MRSProxyEnabled $false
Get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -MRSProxyEnabled $true

If could, I also suggest you try to disable firewall temporarily for check whether this issue caused by firewall configuraton.

If the above methods do not work, you could also refer to this case: Error : Migrating on-prem mailbox to exchange online
