[ActiveDir] MailBox permissioning

[Mayuresh Kshirsagar]

Hi Gurus,   I have a scenario where I have users and mail boxes created on exchange server on one domain. Now I have another set of users in a different domain, who should be able to use these mail boxes, and should have permissions over it.   Eg. User A is in retail domain. Correspondingly user A is created in exchange domain with a mailbox. I want to now have the permissions set so as to make the user A in the retail domain use this mailbox. What attributes should I set on the user side or the mailbox side to do this?   I’ll be doing this permissioning using a meta directory server.   Thanks, Mayuresh.
