Emailing migrated Calendar events

[Jack]

I recently migrated a number of users from one Exchange server to another
(2003 to 2007). Basically we brought them in-house by exporting from the old
system and running "Import" on the new one. The migration went smooth with no
problems. Soon after however, the users started reporting that when they try
to send a exisiting Calendar invitation (one that was imported) they get
errors. In one case the error read that "UserA is not allowed to send on
behalf of UserA" which is really hard to explain to the usuers (basically a
user is not allowed to send on his own behalf). I messed around with
permissions but that did not help. Has anyone come accross this and found a
workaround? The easy one is to recreate the message but I have users with a
lot of appointments.
Thank you in advance,

did they get new exchange accounts? How are they trying to send the invites?

Hi Diane,

They had accounts on the hosted server and I had to create their accounts on
our server (where the information was imported). The names remained the same
and I imported while logged in under their credentials.

From what I understand, the event in question are recurring meetings and
they are just trying to advise all attendees of schedule change or last
minutes additions.

I will try to get more information.

Basically there is a schedule change and there is a popup to notify other
people. It seems that an attempt is made to email through the non-existing
server (the old machine).
