I do have a little problem inviting external users to a folder in O365 SP.
It works flawlessly with an account from another company, but if I use it to invite users from, say, a “normal” microsoft or a gmail address I get a bad request. Funny thing is, manually it’s working.
“message”: “The user has insufficient permissions to create an invitation.”,
External sharing for authenticated users is activated.
Has anyone else experienced this or maybe even a solution?
Any help is greatly appreciated.
