Hi,
we need to reset (delete) all manual setup sharing links of files inside MS Teams and OneDrive. I am able to list alle teams and all including channels via PowerShell but I don't know how to list the files and then to get the sharing info of these files.
Can someone help me how to list the files and their sharing links - to later remove them.
Thanks
Wolfgang
I published a PowerShell script to do just that a while ago, check it out: https://www.michev.info/blog/post/3018/remove-sharing-permissions-on-all-files-in-users-onedrive-for-business
If you just want to report on shared items, here's a more recent script: https://www.michev.info/blog/post/6154/report-on-externally-shared-files-via-the-graph-api
Because my goal is to delete the second script to only report is not what I am looking for.
Am I right your first script checks the OneDrive but not the Files in MS Teams channels?
I know to register an EnterPrise App but what do I have to do to fulfill the needs for $appID and $client_secret ?
I'd still recommend running the "report" script, as it can give you a very detailed breakdown of which items are shared, and how. If nothing else, you can use it as comparison after running the removal script.
Here's an updated version of the "removal" script, which works for both SPO and ODFB sites (Teams sites included): https://www.michev.info/blog/post/6308/remove-all-sharing-links-and-permissions-for-items-in-sharepoint-online-or-onedrive-for-business
As for configuring the application, the important part is to make sure you grant the correct permissions (Sites.ReadWrite.All in this case) and admin consent as well. The $appId and $client_secret variables are used for obtaining an access token for said app. I would strongly recommend that you do not save such values in your script files in plain text, or at all. Instead, replace the connectivity bits with your preferred method, or just use a token you obtained by any other means.
Just in case, here's how to add a client secret: https://learn.microsoft.com/en-us/entra/identity-platform/quickstart-register-app?tabs=client-secret#add-credentials
