Just in time for the end of the month May 2020, Microsoft has again provided a new version of the synchronization client OneDrive.exe (Next generation Sync Client) in the Insiders Ring.
While the Insiders Ring has already reached version 20.084.0426.0006, the Prdouctions Ring will be rolled out with version 20.064.0329.0008.
By the way, the user will only get the Insiders version if you check the box at the bottom of the first tab in the properties. In some companies, however, this is prevented by a group policy.
If you think you have problems with the sync engine, you should have a look at the version first. And if you think you don’t get any updates, you should talk to the administration: The addresses "oneclient.sfx.ms" and "g.live.com" must be reachable and not blocked.
