I am running exchange 2007 SP2.  On Windows server 2003 SP2 64 bit, DS is win 2k3 server.
When any user creates a meeting invite with the VP, they get an email back that says "#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##"
And it's referring to a person that has already been deleted from the system, the VP's old Secretary.
I looked at every option and setting on the VP's account in exchange and I don't see that old secratery's name anywhere there, where do I need to look at it fix this issues, any help?
Here's the diagnostic information.

Get the VP to open outlook and go to Tools | Options | Delegates and see if the Secretaries account is still in there.
Also check his new secretaries account as there may have been delegate permissions set up while in a handover period.

He doesn't have outlook, as he uses enterouge, he has a mac.  Do you know how I would check it on a mac?

So with the new secretary, do I check her outlook, or her account in exchange?

I would check on both the Outlook Delegates and Exchange mailbox for the new Secretary.

Can't help you with Enterouge though sorry, never used a mac.

ok, I just checked the delegates section for both the VP's outlook and the secretary's, and they are both empty.  The VP said he deleted everything in enterouge that deleted any old references, so she's gone from there as well he said.

I'm stumped, Im not sure where else to look to remove her reference from his account?  Any other suggestions?

hmmmm... Can you set up Rules in Entourage (simular to outlook rules)?
Maybe check there are not rules for forwarding appointments linked to his profile.

I'll send him an email and ask him to check that.

I went to his MAC and we looked at everything and there's nothing listed with her name.

Well, what I did is I used Adrestore, and I restored her account, since it was less than 30 days when I deleted it, and now her account is disabled, with no mailbox and when I send a meeting invite to the VP, it works, I don't get the undeliverable for her, so go figure....
So somewhere in AD, there's a reference in his account that points back to hers, but question is, how do I find it? By restoring the account, that proves that I am right, the hard part now is finding the reference in AD.
I have no idea how to do that.  I did use adsiedit.msc and looked at his account, but I ddin't see anything pointing back to hers.  I'm stumped, if ANYONE can help me find out,  I would greatly appreciate it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

you can just leave the account disabled as a work around.

Also, try these commands in powershell to see if there are any permissions on the mailbox

Get-MailboxCalendarSettings "username" |select resourcedelegates

Get-MailboxPermission "username" |select user, accessrights

Thanks, I'll try those commands on Monday.

My backup plan is to just keep her account disabled and alive in AD, but that's not preferred, because same thing happened last year with my Accounting VP mailbox and since I wasn't able to figure it out and I couldn't restore the box I deleted, I had no choice, but to delete his account and recreate it, it was terrible.  I can't do that now, as it's the VP's account.  So I really would like to find a solution for this.

I"ll let you know on MOnday what I find, I'll post it here.

Thanks, Dan.

I've attached the txt document with the permissions, but that doesn't really show me anything.

I know for sure that somehwere in AD, there's a reference to the other users's account, somewhere in AD, but finding it is like a needle in a haystack.  Is there a certain place that I should look at?
