Hi,
I have an new classic full hybrid Deployment with Exchange2016.
Test-migrationserveravailability shows no errors. HCW configuration works with no errors.
But when I try to migrate a mailbox from Onpremises to O365 through GUI I get the error:
Error: TimeoutErrorTransientException: The call to 'https://<servername>/EWS/mrsproxy.svc' timed out. Error details: The request channel timed out attempting to send after 00:00:00. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.
This error came on different mailbox migrations.
Any ideas?
Thank you
