Without testing, that sounds like as reasonable explanation as any. Turning off read receipts for User B should clinch it.

I'm having a similar problem to this, but a bit more confusing:
User A has delegate access to the calendars for users B and C.
When user A sends meeting requests from user B's calendar, user B gets the
read receipts. OK, makes sense based on the below scenario.
When user A sends meeting requests from user C's calendar, user C does not
get the read receipts.
I checked both users' settings and they look the same. Why would B get the
receipts when C doesn't? And how do I stop B from getting them? Is there a
way to do it without turning off the requests for read receipts from A?
Thanks,
Craig

Sounds like User B has read receipts set for all emails sent whereas User C
does not. Check User C. (Tools menu, Email options, tracking options, input
check receive read receipts for all) or are you just talking about the
meeting request receipts???

User B has nothing checked. I made sure of that. User B does not send read
receipt requests, only user A. Your example covered that. User B receives a
read receipt when anyone opens the meeting request email. User C gets
nothing, which is what we want. Is there a setting somewhere I'm missing?
