Hi everyone,

I'm kinda stuck on this one.

I'm trying to revoke the permission of a specific EXTERNAL user on a sharepoint folder thanks to his mail adress.

I tried with http request but i guess it work only with internal user or do i miss something ?

Thanks in advance,

TS.

Hi @tsBlank,

Have you tried using the GetSharingInformation endpoint for the item? This might be a way to retrieve the correct user:

https://sharepoint.stackexchange.com/questions/249791/remove-a-specific-direct-share-link-from-sharepoint-online-or-onedrive

Try an URI like below

_api/web/Lists(@a1)/GetItemById(@2)/GetSharingInformation?@a1='listguid'&@a2='itemID'&$Expand=permissionsInformation,pickerSettings

Paul Matthews has a great blog about this:
