Using server-side synchronisation and Email Router on CRM Online never seems to work correctly, and it is rather unstable.
Customers keep getting an error message such as 'An error occurred while creating the incoming email "xxx" in Microsoft Dynamics CRM for the mailbox ', and there has been no fix available to overcome the issue.
A customer has emails settings as below;
-Server Profile is Microsoft Exchange Online
-Imcoming emails setting set to Server-side Sync or E-mail Router
-Outgoing emails setting set to CRM for Outlook
-Appointments, Contacts, Tasks are using Server-side Sync
We have looked into Workflows and Permissions, but it does not seem to casuse the error.
Even looking at Traces for CRM, it did not help us.
It would be very important for CRM Online users to know that both imcoming emails and outgoing emails are working responsively wtihout any unexpecting errors.
