Unless something has changed, after a mailbox is moved, Outlook
automagically figures this out and connects to the right server, no
additional effort required. The existing .OST should sync without issue
unless the Outlook profile is deleted/re-created which will orphan it. No
client attention was necessary when we moved from Exchange 5.5 to Exchange
2003.

Hi there,

I will be moving users from Exchange 2003 to Exchange 2007. On the back
end, this simply involves moving the mailbox. However, what is the right
approach to use on the user's Outlook client? Does this require deleting
the
OST file, or creating a new profile altogether, or simply changing the
Exchange Server name in the existing Outlook profile? Are the combination
of
Outlook and Exchange smart enough to re-sync using the pre-existing OST,
or
will that cause problems?

Thanks,

- Earl
