Hi All,

When you set up Outlook 2003 to interface with an Exchange Server in the
Cached Exchanged Mode, I understand that your mailbox files on the Exchange
Server are duplicated on your local PC.

But what happens if the files on the Exchange Server are lost?. Is it
possible for the files that are your local PC to be copied back onto the
Exchange Server?

I am asking this question in advance of an Exchange Server
consolidation/upgrade and want to back up what is being stored in my
“mailbox†on the Exchange Server without replicating/moving everything onto
(local on my PC) *.pst files.

Regards,

Scott
 
You should be able to startup offline and get at whatever the OST has and
export to PST.

As for the Exchange consolidation/migration, the site admins should have a
firm grasp of disaster recovery if the consolidation/upgrade goes south.
Users should never have to worry about this if they are doing their job. :)

Neo,

OK, Thank you for your response.

Here is a follow on question.

If you have the Cached Exchange Mode enabled, and e-mails are subsequently
lost on the Exchange Server, will e-mail that is locally cached on your local
PC be “sucked back†to the Exchange Server or deleted by Outlooks or the
Exchange Server’s attempt to synchronize the local cached files with the
files on the Exchange Server?

Regards,

Scott
 
Keeping focuses on the original question about migration and/or disaster
recovery situations, I guess this all depends on what is going on with the
server at the time and/or how the migration of mailbox is done from one
server to the next. For example, lets say the site brings a new exchange
server on that is part of the same site. If staff move the mailbox from
server a to b, then Outlook is just as happy as a clam.

Now lets say that the migration required exporting the mailbox from server
a, mailbox deleted, mailbox created on b. In this case, Outlook will not be
happy and you are going to have to access the OST while offline to deal with
whatever items transpired while disconnected from server. (e.g. export to
pst and then later import.)

Last but not least, lets say a database gets corrupt and the staff decide to
start with a "clean" (read new) exchange database (discussed in
http://support.microsoft.com/default.aspx?scid=kb;EN-US;282496). Outlook
2003 in cached mode will detect this and actually come up in what is known
as recovery mode. This is feature is very new where it gives the user the
opportunity to pick online vs. offline. This ensures that what transpired
in the OST while disconnected is not lost as the user can select work
offline and export the data to a PST for importing to the server later.
(Earlier versions didn't detect this state and what happened automatically
is that outlook would create a new OST and the old would become disconnected
w/ no easy/cheap way of getting the data back.

ps - in previous versions of Outlook (e.g. 97/2002) did not detect server
mishaps. generally what happens is that the ost file becomes disconnected
and there is no way "easy" or "inexpensive" way to get the data back.
