Microsoft Dynamics 365 - Service Update 225 Release Notes

Service Update 225 for Microsoft Dynamics 365 9.1.0 is now available. This article describes the hotfixes and updates that are included in Service Update 225.


Note: Service Update naming convention has been revised to clarify the link between the version number and Service Update number.

For this reason, Service Update numbers may not always increase incrementally.
