Exchange 2010 Distribution Lists
Posted on 2012-09-13
I have a quick question. We had one email come in with a BCC to two different distribution lists. These two lists have exactly the same users in them. I would expect the email to show up twice in the users mailbox, but it only showed up once. Putting aside the reason why we would have two distribution lists with the same people in it, why would the users only get the message once? Did Exchange see the same message ID going to the same people twice and cancel the second instance of that message?
