SharePoint external sharing - external users not receiving email invite?

I've been experiencing a huge amount of difficulty in trying to enable external users access to one of our SharePoint sites. We have a site collection, called 'Projects', and I am attempting to share...

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.

Hi Toby McDaid ,

Last thing I can think of - did you get an email cc'ed to you with that successful gmail account? If not your end may be blocking no-reply@sharepoint.com

There might be something that stands out if I was troubleshooting in person but seeing as that screen is fairly standard for SharePoint Online I would raise a ticket with Microsoft as they will be able to view your desktop and see what's happening in the back end.

Kind regards

Andy

Originally when I first configured external sharing months ago I did receive a CC email, so it seems as though something has broken since then.

I have logged the incident with Microsoft and scheduled a call with them, so hopefully they can resolve the issue. Will post the solution here if we reach one as I'm sure it could be of interest to others.

Appreciate the help you've provided!

Thanks,

Toby

Hi Toby McDaid ,

I have the same issue, did you get anything useful out of that call with Microsoft?

    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.
