Service Update 34 for Microsoft Dynamics 365 9.1.0


Service Update 34 for Microsoft Dynamics CRM Online 9.1.0 is now available. This article describes the hotfixes and updates that are included in Service Update 34.

Please note that our naming conventions have changed to clarify the link between the version number and service update.  For example, Service Update 34 will correspond to version number 34XX.  Occasionally a Service Update will be canceled and all the associated fixes will be rolled into the next Service Update, thus Service Update numbers will not always increase incrementally.

As this release is deployed globally, we will continue to add fixes and the version number may change.  Check this article regularly as we continue to document fixes added to this release.
