Sending email to someone at contoso.com

[TBone1985]

A user reported they got a NDR for an email sent to someone at contoso.com. Of course, this user did not send such an email and the email was not in their sent items. I first thought it was some system we had in place that may have been sending to this address.

After a few hours of digging around, I found that emails had been sent to this address randomly for at least the past 30 days, but not until 4/10 did we start getting NDRs. I finally found the issue:

If I go to my public Bookings with Me page in incognito mode and try to book a meeting with myself, but close the window at this screen, an email will fire off to email address removed for privacy reasons, sending me an NDR.

Same here ...

The same behavior just started to happen to me today too, while I visited my own Booking page, I didn't even bok any appointment!!!

I'm having this issue as well.

Same here.

I'm also getting the NDR referencing email address removed for privacy reasons

@TBone1985 

Me too.

Seeing this as well. Putting in a ticket with Microsoft.

We too are getting this @TBone1985

Any solutions? I just started setting up my Bookings Page a few hours ago and have had a dozen or so of these emails streaming into my inbox!

So far in other MS Q&A forum I found a temporary solution which could work if you are Exchange administrator:
Create a Mail Flow rule in the Exchange Admin Center that checks to see if the recipient is the person 'someone at contoso.com' and then drop/remove email.

I'm not an Exchange Admin. I just created my own Rule to filter to the delete folder.

@TBone1985 TMK, Microsoft has this in their bug fix roadmap.  Guess it takes several weeks to get the right developer on it.
