Hi Qualle

It turns out our problem was a bit of a strange one, Microsoft noticed that we had the azureb2b feature enabled on our tenant, which is still in preview. After a colleague of mine disabled this the external sharing seems to work without any issues.

This was the feature causing issues:

Not sure if it would be the same for you but worth checking this out.

Toby McDaid Has Microsoft provided any information if they will be fixing this and when this feature will be in GA?
I am testing scenario -
Disable "Members can invite guests" in Azure AD (External Collaboration Settings)
Enable one time passcode
In Sharepoint Online Set External Sharing to "New and Existing Guests"
With all this preview setup sites that i share with guests are not receiving any emails.
