how to tell if a outlook file was pop or imap

I have an Outlook 2010 folder that was taken off a failed hard drive.  In it there are pst files modified yesterday before the crash.  I need to set up these three different e-mail accounts (and data files I'm referring to above) on a new computer in Outlook and need to be sure if they were configured as pop or imap.

Thank you.

If there are no OST files, and only PST files, the the accounts will be POP3
The pst file won't give you any info on whether the account was setup for IMAP or POP. Only if you were using MAPI (exchange server) would you have had an OST file. But IMAP and MAPI are two different things.

Why do you need to know how they were setup anyway? That shouldn't matter. Just setup the accounts again, and if the mail server supports IMAP use that, as it is the better protocol than POP.

rindi, you cannot say IMAP is better than POP3. IMAP needs to keep all mails on the server, and keeps the folders in sync, while POP3 creates a local copy of each mail no longer having a relation to the server copy, which usually is removed immediately.
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

That's just one of the reasons why IMAP is better than POP, the messages stay on the server where they belong and can get backed up. You can then connect to your email with several clients and see the same thing, and you don't have to download the complete mailbox to your device wasting local space and network bandwidth. Besides that, IMAP supports sub folders so you can organize your mail on the server, with POP you only have the "Inbox".

I just got back from vacation, out of the country.  Sorry for the delay.
So there is no way of telling by looking at the data file if it was imap or pop3?  I already set it up as pop3 based on Johns comment, whoops. Well at least I have a 50/50 chance of having gotten it correct.  

I needed to know because it needed to be set up the same way as before, simply put.  If I saw the second post I would have dug a little deeper to find out but I was in a hurry.  Oh well!

So no way to tell by the data file?  Good to know.  For some reason I thought there was something obvious about the imap data files I've worked with in the past but maybe it was just how they were named.  Ok, so once again... .pst can be either imap or pop3 and there is no way of telling by looking at the data file, correct?

Ok, thank you.
I personal don't like imap.  It's to slow!  Pop3 doesn't sync but at least it's fast.  Hosted exchange seems the best option these days for a few extra bucks more than a POP account.  That's my 2 cents. ;-)
I don't agree, imap isn't slow, and you are far more flexible with it than with pop.
