We are unable to send or receive mail through Zoho using our Office365 server this morning. The error message is "
| The Server could not be connected. Check whether the Server is available to connect in the given name and port number. |
|
The account is disabled now, and when I try and enable it, it says that outlook.office365.com is an unknown host.
It has been working fine for months, until this morning.
Ideas on how to fix it?
