Calendar invites sent to another user

Okay, this is a strange one.

On a small domain. Win server is 2003/Exchange is 2007. Though I don't think that's where the issue is as we've recently migrated over from Exchange 03.

Person 'A' is using Outlook XP 2002. Person 'B' is using Outlook 2003.

Person 'C' sent a calendar "meeting" request & invited 7 other people withing the domain including person 'A' but NOT person 'B'. This was 2 days ago.

Today, person 'C' canceled the meeting & immediately got an out of office message from person 'B'.

If I send email to person 'A' it goes right to him. Nothing more comes of it.

HOWEVER, if I send a calendar invite to person 'A' I will get the out of office reply from person 'B' (note, I'm doing this from a different account as the "OoO" message is only sent once per person.

My question is, why is this happening. It's consistent. Even if a person outside the domain sends an invite to person 'A' person 'B' will also get the invite.

Person 'A' is NOT sharing his calendar or anything else that I can see to person 'B' There is nothing in either of their exchange accounts that I can see that would account for this behavior. To 'A's knowledge, he has never forwarded anything or given permission to 'B' for anything. I'm at a loss on this one.

Any ideas anyone?

Anyone at all? I've been unable to locate a reason for this. Please help.

How hard would it be to cancel A and B's accounts and then restore their data but not their settings?

Perhaps what ever has them inextricably linked will go away.

You could try one at a time and see what happens.

Logistically that would be very difficult. One person is in a different part of the country. The other is a recent addition & it's unclear as to how this even started.

Set up remote access. Our company does all of our installs and OS/application fixes via remote computing. Many of these fixes are done from our first level help desk in India back to the US.

I have the same problem.

In my case it's an Exchange 2003 server.

All the clients have Outlook 2003.

Person A intives B and C, and he get's an out of office from person D and E.

None of the mailboxes have any links between them.

It seems to be located in one office only, none of the other linked Exchange servers exhibit this problem.
