Move Request is failing with “Microsoft.Exchange.MailboxReplicationService.ProxyService’ failed. Error details: A call to SSPI”

I got a situation where the move request from 2013 to 2016 Exchange server for all mailboxes all databases is failing with following error:

The callĀ“to ‘net.tcp://<Exchange 2013 FQDN>/Microsoft.Exchange.MailboxReplicationService.ProxyService’ failed. Error details: A call to SSPI failed, see inner exception. –> A call to SSPI failed, see inner exception. –> The target principal name is incorrect.

After some troubleshooting i found that the MSExchangeMailboxReplication Service on 2013 is running with Administrator account and not as Local System which the default.

After changing the logon to Local System and restarting the service the issue got resolved.

Hope this will help other people with the same issue!
