I have several mail accounts, with yahoo and such (pop). I have two computers, one at home, and a laptop. I use Outlook that gathers the new mails from these different account, and then I put them into several Outlook folders / subfolders, by drag and drop. (I also could buy some add-in that would help me here, and will probably do so: There is QuickFile (70$), SimplyFile (50$), SpeedFiler (40$), and also ClearContext (90$) - SimplyFile seems to be best to me, but I would have to try them first.)
Now I don't want those mails, in yahoo, etc., to be deleted after downloading, but want them to be preserved there, too. This means I cannot download mails from both of my computers, as I would like to do, since Outlook in computer 1 does not know that I did download all these mails by Outlook in computer 2, and I would quickly create total chaos - this goes without saying, and I never tried to do such an idiotic thing.
What I do, I use computer 1 for accessing my mails, then copy my Outlook pst file to computer 2, then access my yahoo accounts again. This is a lot of fuss, but should work.
I also had a look at alternatives: I read all available reviews on Outlook synch tools, but I see there they all seem to be rather buggy. SynchPST from Wisco (90$), for example, will be available from bitsdujour soon, but reading the user reviews on cnet.com will probably make you refrain from your purchase (and its competitors don't seem to function better).
Then, there is "Exchange Hosting", for example from Rackspace.com, but one "mailbox", as they call it, is 10$ per month, and I don't know how many of these "mailboxes" I will need - in the end, such a solution seems to be the very best one here, for people like me who don't want to switch from Outlook to google.mail and similar, and who want to use several computers to access their mail. (But I don't know anything about Exchange, and Rackspace won't explain their system in a way I am able to understand.)
Now for my immediate problem, though.
As said, I use computer 1 with Outlook 1 for accessing my mails, then I copy the pst file to computer 2 and want to use Outlook 2 there, then again I want to transfer that same pst file back to computer 1 and access my mail account by Outlook 1, and so on.
Now, the second computer, with the refreshed pst file coming from computer 1, will NOT "know" that all these mails are downloaded and stored and categorized within my pst file, but it will begin to download thousands of "new" mails.
This means, the second computer, the second Outlook installation, with the same pst file that functions well in computer 1, behaves as if I had a second pst file here, and not the pst file from computer 1.
So, even with the fuss I'm going into in order to make my system work (I know it's crazy, and I should work with google.mail or something like that instead), nothing works, and I can't access my mail but with one computer, not both.
Does anybody know if I must reset some option within that second (identical) Outlook installation on my second computer, in order to stop that second installation from downloading all these mails that are already within its file system? (It's that unique pst file, WITH all these mails within its hierarchy - I see them, I can open them, and notwithstanding that, that second installation downloads all these files again, when the same pst file in computer one behaves normally: Here, only new files are downloaded.)
I should add that my system is exactly what they say you should do on numerous web sites, and nowhere there is a hint at the problems I encounter here.
