Exchange & Outlook AutoComplete Entries

[ITGURU]

Hi

Looking for a solution to the following if possible.

We are changing email domain, and I will have emails set up on our exchange server so that users can continue to receive mail on both the old and new email domains, but the new domain will be set as primary for sending and reply to.

 

However, despite the number of times you tell users to use the GAL for emailing users internally, they will start typing the name into the to... field and selecting from the list there.

 

When we change, users will continue to do this, which means it will still be going to their old email address, which doesn't matter in a way as they'll still come through on the same mailbox, but is there a way to clear the autocomplete entries for all users, so it can start from scratch rather than each end user having to do this through the outlook options.

 

Thanks.
