Ghost users after migration

[oneindelijk]

Hi,

After installing a new exchange server one user experiences the following problem:
When entering a new event in the calendar with attendees (from the same domain) the user immediately gets an error mail returned saying that the message couldn't be forwarded to two users who were deleted before the migration.
The exact error message in the mail says:
"The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.

<domainname.be #5.1.1>"
(domainname is of course the domain from the company)

I've checked all exchange settings for the inviting as the invited user, but both have only the default settings applied.

Any idea where I should look or what a solution might be ?

The invitees have nominated delegates who have since left the business?

Yup, agree. That's the usual cause.

Yes, but I believe these users have left the business before migrating to a Windows 2008 SBS.
Probably the user had a setting in his exchange profile to forward all mails to these two users, so now it seems as if the new exchange is still forwarding these mails without an appropriate setting in the profile.

So have you checked for any "Ghost" delegates or not?

Not a setting, no. A delegate.
