Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi AM199308,
According to my tests, the behavior you have described is "by design". Teams is using SharePoint infrastructure and files libraries for Channel sharing. Also, the source of file and folder modification time is SharePoint information.
I searched for a workaround, however Microsoft Teams doesn't have this kind of settings. To share your suggestion with our Product Group Engineering Team, please post it onhttps://microsoftteams.uservoice.com/.
Your time and understanding will be highly appreciated.
Best regards,
Nemanja
