Forwarding rules in affect after rules are deleted

[Anne]

Hi I have an unusual situation.

We have a mailbox setup for a conference room. We have
two people who monitor and respond to messages to this
mailbox.

The mailbox was setup with these two people as delegates
who would receive copies of the meeting requests and
messages in their own inbox.

We have removed the rule to forward messages from the
conference room mailbox to the delegates, and we have
removed them as delegates, opting instead to give them
permissions to the mailbox and add that as an additional
mailbox in their folder list.

The problem: they are still receiving all the meeting
requests into their own inbox's.

Any suggestions?

Thanks
