I will try to make this explanation as simple as possible. We have a client who has 3 room mailboxes set up on their premise based 2007 Exchange. The user accounts for the room boxes are also enabled. The receptionist has each of these mailboxes added under the same profile in her Outlook 2010 client. Users from her domain and a completely external domain send mtg. requests to these rooms and she manaully approves or denies the requests in order to schedule mtg. time for their 3 conference rooms. Everything is working just fine, except that when she would receive requests from one particular user in the outside organization to ONE of the particular rooms, she is not able to edit her response to the meeting requests. However, this same user can send to either of the other 2 rooms and she can edit her response to the requests just fine.
The thought was that maybe this was profile related. So, I attached the room box in question to my outlook 2013 client and got the same results. I also found that it is behaving the same way when I send requests to the room. To answer the next line of questioning, are my settings correct? Yes. Both my settings and the gentleman trying to request her mentioned above. So, now, when I send requests and this other gentleman sends requests to this one room box, the response it not able to be edited and the email with the request actually shows that the sender has not requested a response, when we both actually have.
The next thought then is that maybe the room box is corrupted somehow. So, let's create a new room box and check it out. It is having the same issue as well.
So, does anyone have any insight into why this one room mailbox allows most people to request meetings and allow the manager of the mailbox to edit their response to the requests, while for a select few it will not allow the manager to edit their response to the requests? On other point of information...she is logging directly into the mailbox itself and not just including it as an addiditonal mailbox through the advanced tab of the account settings.
