I had almost forgotten, that on the Microsoft Patchday also a new Version of Azure FileSyncAgent was available.
When i look at the Azure Storage Sync Service i see that the Registered Server runs FileSyncAgent 14.1
Azure File Sync Agent v15.0
I've downloaded the MSI but was not able to install, without uninstalling the Software first
Instead i used the Windows Update Package
After a Reboot i can see the new Azure File Sync Agent Version in Azure Portal
