For those who have installed Exchange 2016, you might come across some errors or warnings not seen in previous versions of Exchange. To give you an example, MSExchange UnifiedPolicyFileSync warning that keeps getting logged in the application log:
![Exchange 2016 - msexchange unifiedpolicyfilesync Exchange 2016 - msexchange unifiedpolicyfilesync](https://www.collaborationpro.com/wp-content/uploads/2017/06/unified.png)
Is there a solution? No, not at this point, this is apparently a known issue that they say will be fixed in future release.
Hope it helps.
