File ownership and NTFS permissions removed from Office documents
Have a good one here. We have some non-domain computers accessing a share on a domain file server. There is a firewall that is allowing 445/SMB for drive mappings via AD authentication. Users are abl...
We continue to see this happen to individual users. We resolved it by closing down all office products and then reinstall Office 365 from the portal. The permission are only missing from Word & Excel files. I re-apply permissions on the impacted files and the installation of office fixes all future issues. We are a large organization and see this happen a few times. Almost like a Windows/Office update breaks the NTFS permissions for Office files.
- We are also seeing this issue in a NTFS / Samba share environment, we had this occur on our old 2008 R2 servers and then at the same time it started to also occur on our newly built 2016 servers. We have had these shares/clusters for years and from my gut feeling it seems to have only occured since moving away from another AV product and over to defender.
We have an open case and also tried this command as suggested further up "Set-MpPreference -DisableScanningNetworkFiles $true" and unfortunately it didn't make any / much difference. For us this does not only affect office (word/excel/powerpoint) files it also affects pdf's.
Anyone else have any info on this?
