Email notification of delegates

[opaled]

We have resource mailboxes set up (for conference room scheduling), whereas each resource has one or more delegates. The delegates are supposed to receive an email notification when a request is made to schedule the conference room. This all worked well under Exchange 4.0. Since we upgraded to Exchange 5.5, the delegates for existing resources no longer receive an email notification for conf. room scheduling. I created a new resource and made myself a delegate (for troubleshooting purposes). My &quot;new&quot; resource works as it's supposed to. So the problem seems to only exist for resources that were created before the upgrade from Exchange 4.0 to 5.5. I've compared the delegate settings for the new resource against the old resources. All settings appear to be identical. Anyone else have similar experiences? Solutions?<br>
