outllook calendar acceptance emails being sent twice

Hi

One of my users sends an invitation for an appointment to three other people in the company, by adding each person's email address into the From field.  Each person receives one calendar request from the originator.  When each of the three recipients opens the invitation and sends an acceptance email, the originator receives two acceptance emails from each person.

Any help with this would be very welcome!

OK, finally got back on site and resolved the issue.  It turned out that the user had delegated access to the global group for the company instead of individual users.  Once I deleted this and added the appropriate users individually, problem disappeared.

Hello Waleeda

The only rule defined redirects some specific incoming emails to a specific folder.

I have done some further testing and can confirm the following:

1. User A invites users B,C,D.  Users B,C,D each receive a single request.   If user B accepts, user A receives two emails, one to user A, the other to a security group of the company domain.  Users C and D each receive an email confirming B has accepted.  The same pattern occurs if C or D accept.

2. User B invites A,C,D.  User B receives the request (even though he originated it) and A, C, D each receive two requests.  One request has users A,C,D in the To field, the other email has the name of the security group in the To field, which I believe is the global address book.

So it seems that whenever an invite is raised, the system is generating a second message to the global address book.

3 computers are running Outlook 2003, one is running Outlook 2010.

Thanks

Glen

becuase most of these issue will be because of the rules conflicting

Hello Waleeda

I have checked all four computers and only two computers have any rules defiined within Outlook, and each of these only have a single rule.  One rule moves emails with certain addresses to a folder, and the other rule just remove categories from incoming messages.  No other rules exist.

Thanks

I have removed both rules and sent another test, which is still misbehaving.  There certainly seems to be a setting somewhere that is copying the originators email (plus any acceptances) to the global address list but it is certainly not from a client-side Outlook rule.

Try deleting the profiles of the users, and recreating them.

Ok, I'm not at the customer at the moment but will arrange to do this.  I may in fact create 4 new test users, create a profile for each on the PCs and run the same tests.

I'll update you once this has been done.
