Databases on network share can’t be accessed by multiple users in Office 2016 (KB4484211)
This update fixes an issue in which Microsoft Access databases that are stored on a network share can’t be accessed by multiple users simultaneously in Microsoft Office 2016 after Security Update KB5002099 is installed.
HCL release fixlet for the new update KB4484211 to rollout the patch on all affected computers asap.
I’ll ask around internally to see if there are any plans for this one, but since this KB is not in the MS update catalog there will probably not be a fixlet. Unless of course this thread gets popular and PM decides to release one anyway - which is certainly possible.
It is very critical to us as well. This has already caused two separate Sev1s each of which had to require KB5002099 to be uninstalled manually on several hundred machines.
