Outlook 2007 User Connected To Wrong Exchange Server

We have 2 separate Exchange servers for two separate companies. Apparently, a user's computer was setup with their Outlook 2007 pointing to the Exchange server of Company A when it should have been setup pointing to the Exchange server of Company B. How do I change their profile to use Company B's Exchange server while maintaining their folders, contacts, messages, etc? Thank you!

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You would have to export the PST data for the user from Company B and restore it into Company A. Once done (and verified), delete the Outlook profile on the User's computer and set up a new profile pointing to Company B. ... Thinkpads_User

You cannot maintain everything when changing profiles here is what you have to do.

Open Outlook
Click File....Import and Export
In the list chose "Export to a file" click next
Then choose Personal File Folder (PST) click next
In the next selection chose the root folder, e.g. Mailbox - User Name click next
Choose to save somewhere on the c: drive or desktop click next
A window will appear to “Create Personal File Folder” Click ok

From the Mail Settings in Control Panel,  Create the new profile on the other exchange server
Click File....Import and Export
And choose from another program or file click next
Then choose Personal File Folder (PST) click next.
Choose the file you exported.
Now all items will import to the other profile.
You can't have 2 exchange mailboxes under the same profile.  Create a new profile, setup for Exchange server B.  Before that, export all the data you need to a .pst file and import that back in later.  If you want to keep the same folder structure, look into using a program called Exmerge, this will merge pst files into your live mailbox.

Thanks for the info. Did the export and all went well.

JohnLo, the beta sounds intriguing. I have it, but did not install yet. Maybe this weekend
