Is it too late to make a feature request?
I know it probably is, but I figured I would throw it out there anyway since I routinely am asked this question by customers as an Exchange consultant.
Is there any way to configure individual DLs to not deliver email to users when they have their Out Of Office set?
In theory it would be just another true/false attribute of an email enabled group, and something the message catagorizer would look at when it was expanding messages.
Nested DLs would not be a problem, because the expansion process could decide that if any DL along the path of expansion was set to require delivery (the default setting) when a person is Out Of Office, then the message would be delivered.
So many customers have many DLs that they would like to give their users the option of not receiving email when they go on vacation or whatever. Today removing ones self from email groups either requires some custom third party solution (with user intervention requesting that they be temproarily removed), or an admin making the changes manually.
In theory this option could be set per DL (with the default being set to always deliver) and give list owners the ability to make their lists mandatory or not.
Just a feature I have had asked of me over and over again.
