I’ve came across a few random cases of the SQL Server error while using Microsoft Dynamics CRM Online the past few weeks. I’d seen this type of error in the past. It seems to occur more often during major updates such as the December 2012 Service Update “Polaris” Release – which is being applied to Microsoft CRM Online organizations in the past two weeks.
SQL Server error – SQL timeout expired.
In most cases – this SQL Server error doesn’t cause any serious issues and can be ignored. A quick refresh of the existing Dynamics CRM record and continue your CRM operation as normal should suffice.
Now if you find that this error repeats over and over again consistently – I’d recommend opening a Dynamics CRM support ticket to further trouble-shoot the issue with a Microsoft CRM Support Engineer.
