Where does Outlook store info for "leave a copy of messages on the server"?

[Alexban]

Hi, I have a dual boot Win Xp / Win 7 setup and I want to be able to use the same .pst without having to download same messages twice and I'm trying to figure out where does Outlook store information of the messages it has already downloaded. I've used Regmon and Filemon but I wasn't able to figure it out. Does any one knows?

That information would be to the mail server at the time of message
retrieval. It wouldn't be stored stored locally. Why do you think you need
it to be?

I am wondering a similar thing though with a different situation. Instead of
a dual boot setup, I am copying my pst file between two PCs. So whenever I
run Outlook on the PC I've just copied the pst file to, it downloads all of
the email received on the server since the last time I collected email on
that PC. If I configured Outlook to delete mail from the server after
downloading it to the PC, then that wouldn't happen. But I've had too many
instances where I wanted to access email while away from home, so that's why
I have Outlook setup to leave the messages on the server after downloading
them so I can manage email from any PC.

Because of this I am hoping that the indicator that the mail was downloaded
is on the PC and not the server. I've never really looked for it to try and
determine if this is in a file on the PC or in the registry. But it would be
nice to know if controlling this is indeed possible so I wouldn't have to
keep deleting the same messages every time I run Outlook after copying the
pst file from the other PC.

Any help on this one way or another would be appreciated.

It has to be on the client because if I use the SAME pst in another Outlook installation all messages from the server are downloaded again although they are already in that pst. I found this: http://superuser.com/questions/4553...mark-of-emails-downloaded-using-pop3-protocol where it says that Outlook Express keep this info in Pop3uidl.dbx

It's a hidden message stored in the pst (under the inbox's associated
contents) and is tied to the computer and account that uses it. You can
view it using MFCMAPI but you can edit it or use it to control the download
in other profiles except the one that created it.

Each account has their own mailbox manager file and its stored in the
default account's Inbox.

If you're going to use a brain-dead posting interface like msgroups.net, at
least press Enter at the end of each line, because your posting interface does
not wrap text and it comes out as one big long line, makeing it very difficult
to read. You'd do better using a real newsreader.

I use a triple-boot system (XP, Vista, 7) and use the same PST across all.
The secret to achieving what you want is to not keep messages on the server.
If you allow each Outlook account that feeds that PST to delete messages that
are downloaded, you won't get duplicates. There's no way to prevent them if
you leave copies on the server, since the informaiton about what has been
downloaded so far cannot be shared between the two operating systems.

That's "...can't edit it or use it...".

 

[Russ Valentine]

In Outlook, client side information is usually stored in a hidden message.
That information is unique to the profile, not the PST file. So when you
change profiles, any messages you left on the server will be downloaded
again. So if you're leaving messages on the server you won't be able to
achieve what you want.

Brian thank you. I was afraid that would be the answer.
