A user created a new Appointment in his Outlook 2010 calendar and sent an invitation to several other users. After getting a confirmation from the attendees, he received multiple Read Receipts from them as well.
The Read Receipts state, that the invitation message was deleted while it was unread.
The user had no configuration for Delivery or Read Receipts in Outlook.
Where do those receipts come from?

Does the user have an additional device that syncs with Outlook? Such as a smartphone? (Iphone, Android, Windows Mobile, Blackberry, etc) I recently encountered a situation where a user was receiving the same Read Receipts over and over but it turned out that the cause was her Iphone.

I'm not proficient in blackberries, but you may want to ensure there are no Read Receipt settings enabled on said device.

The strange thing is, only the invitations were affected, no other mails.

Hmm... I'll look through my outlook 2010 settings and see if there's something in there we could change. Is he continuously receiving the receipts?

No, not in the last few days.
It first occured after the Update Rollup 1 installation for Exchange.

I was informed that this is a known bug in Exchange 2010.
I hope it will be fixed in the next update rollup.
