I have tried the above twice and still unable to send from Outlook 13 (Office 365)(Win 10). I have deleted 2 read receipts which were stuck in the outbox. Still cannot send.
I have several Gmail accounts running fine from same Outlook.
The error message says
"Sending reported error 0x800CCC0FServer responded: 550 isn't on our network to be able to send mail"
Have checked this error code with MS and it comes up with information from 2003! XP!
Have run the scan twice and rebooted. No Faults found.
Any help gratefully received.
