MVISION Endpoint DLP does not block uploading files with Microsoft Teams


I want to protect some XLSX files with MVISION Endpoint DLP restricting upload for those files in MS Teams Desktop, but It does work.

I have a DLP Policy assigned to rule sets one for Application File Access Protection and other one for Clipboard Protection, both applying to classification (files already registered and creating package) and blocking action, teams.exe is the application file.

any ideas how to achive this?

Re: MVISION Endpoint DLP does not block uploading files with Microsoft Teams

Hi guys for those who have been experiencing this MFE Endpoing DLP behavior I have some addiontal information.

We detect that DLP only block upload files to MS Teams, if that file was not previously uploaded before applying policy. If that file is inside Teams DLP will allow to upload it. but if you rename  the file will be blocked.

Another problem I am facing is after applying dlp policy, although new files are blocked if you exit teams or restart computer MS Teams will not start displaying the following dlp message "Sensitive content was found in file icudtl.dat the clipboard was blocked"

If you have any ideas I appreciate your help.
