NDR message from user no longer in AD


The users keep getting a NDR 5.1.1 message from a user who has been deleted from AD over 6 months ago & is no longer a member of the particular group. The username does not show up in AD when you do a search. The NDR activates only when a meeting request is sent for this particular group.

The delegate can become hidden if deleted from AD. You can try this if your group only has a few members:

1. Go to their machines, export Inbox rules to a file on desktop.
2. Start Outlook from the command line with the switch "cleanrules"
3. Send an email to the group, see if that solves it. If needed, re-add the rules by importing from the desktop file.

Then make sure that the user is not listed in that group
Open the group you may find an SID, simply remove it
This is a delegate problem - check each of the users in that group (check their outlook settings) and make sure the old user is no longer listed as a delegate.
Easily manage email signatures in Office 365

Managing email signatures in Office 365 can be a challenging task if you don't have the right tool. CodeTwo Email Signatures for Office 365 will help you implement a unified email signature look, no matter what email client is used by users. Test it for free!

If you have sufficient rights, you can run this script on your domain to list all delegates on the domain:

ldifde -f C:\delegates.txt -d "ou=users,dc=domain,dc=com" -l name,publicDelegates,publicDelegatesBL -r "(|(publicDelegates=*)(publicDelegatesBL=*))"

Change the section for your domain information, and also add the right file name (delegates.txt in the example).

This code will dump all AD objects in the "Users" ou to a file, where those users have either publicdelegates or publicdelegatesbl set. A description of the two attributes:

publicDelegates - This attribute stores the user that was configured as a delegate (the secretary).
publicDelegatesBL - This attribute stores the user his mailbox that was configured with a delegate (the manager).
That command would be fine - except that Users is a container and not an organizational unit
