Updating/Altering recurring meeting invites
 

Hi,

We have recently migrated from UNIX based email system to Exchange server
2003. There is a strange problem in updating a meeting invite created before
moving to exchange server.
Everytime i update an earlier meeting request, i get the following error:-

"You do not have permission to send to this recipient. For assistance,
contact your system administrator.
ex1.domain.com #5.7.1".

However, when i create a new request and update it afterwards there are no
problems in sending the updates.
Any help is appriciated.

Thanks
Ashish
