My situation is this:
I had a distribution-group, let's call it
But, since the member-base had grown and they wanted to be able to send mail (from that adress), I thought "Hey, let's turn it into a Mailbox".
So, I deleted the distrubition-group and added a new mailbox (with the same adress), let's call that
My problem is the following:
Since Outlook caches all the address's it encounter by default, I'm now stuck with a large group of users which, whenever they try to send a mail to New Leaders, their mail end up being reported as "Undelivereable".
Now, to my question:
Is there any way to clear the cache of Outlook for a large amount of users without actually doing it by hand?
(Also, I had somewhat of a brainfreeze when I wrote the
subject, so if you think of something more appropriate, please do change it!)
