Seeing Exchange Admin Permissions
by DevX Pro
We use a GG in the NT domain to assign permissions to Exchange Admin. I have added a backup person to this group, thinking that they would then have the same admin permissions as I do, the Exchange admin. Problem is, they seem to be able to see everything in Exchange Admin except for the Permissions tab on the properties page, which I do see. We run Exchange in its own domain with a trust to a master domain with all the users in the master. Any clue why these other individuals don't see all of the tabs?

Monitoring Mailbox Contents
by DevX Pro
I have the need to monitor a mailbox. The mailbox is located on a local server, but the person accessing it is in another country. The person who needs to monitor the mailbox is also in the other country. Adding rules to Outlook is out of the question and setting an alternative recipient will not work either, because this fails to send the message to the original recipient. I need to make sure that all intended e-mail reaches the original addressee, but also goes to his manager. This also rules out setting his box up as a group. If the employee has his mail client set to delete messages from the server, then the manager will not see them.
Preventing Users from Deleting E-mail
by DevX Pro
I would like to prevent users from deleting e-mail in Outlook 97 on a Windows 95 or Windows NT workstation in combination with Exchange Server on an NT server. We use Exchange to retrieve and send e-mails and the clients use Outlook 97 on their PCs. Is there any possibility to prevent users from deleting received and sent e-mails so that this can be done only by the administrator?
