I think removing a user from a shared mailbox would be possible to build using MS Graph APIs… what do you think? Has someone tried this? Thanks!

@nivasan Not fully. Removed shared mailbox access means revoking a mailbox-level FullAccess / SendAs grant and those are only possible to change through Exchange Online. Graph doesn’t expose that today. 

MS Graph has mail-folder permissions which is not the same since that’s for folder sharing, not shared mailbox access

A possible solution would be this flow
