Outlook by design is not supposed to change the meeting organizer AT
ALL. I recently had a user who had a similar issue, but not exactly
the same.
When she received updated or forwarded meeting requests from 3
specific individuals she could not accept them. She would get an error
that she did not need to accept the meeting request because she was
the organizer! When I checked the calendar of the one she received it
from it did not show this user as the organizer however, it showed the
sender as the organizer.
I finally was able to get a solution working with Microsoft and this
is what the solution was:
Error message for Meeting updates and Forwards "As the meeting
organizer, you do not need to respond to the meeting."
RESOLUTION
===========
1) Took backup of the Calendar in a PST.
2) Opened MFCMapi (which I downloaded for free from micrsoft.com/
downloads) and opened affected user's mailbox.
3). Closed Outlook
4). Run MFCmapi.exe
5). At the top of the screen, choose "session" and then "log on and
display table".
6). Select the desired user when prompted.
7). Right click the "mailbox-username" and select "open store"
8). Expand the "root-mailbox" and then expand "IPM-SUBTREE"
9). You should then see the user's calendar.
10). Right click the calendar and select delete.
11). GO to Start/run and in the "run" box type "outlook /
resetfolders"
12). Then we imported the contents of the PST to the Calendar in the
mailbox.
13). After testing the Meeting update we were able to Accept or
Decline it.
