When browsing a fileserver direclty from Office applications as Excel/Word, it takes a long time to connect to the shared-disk, so opening/saving files are a problem (see screenshot).

error loading "We are connecting to \server\share, please wait."

I have trouble to resolve this. This does not happens if we browse the server apart from Office applications (Windows Explorer, notepad,...). Office is updated(2206). It happens to all computers on the network.

Fileserver is Windows Server 2016 and everything is on LAN.
