Thunderbird Portable

Is there a way to synchronize the profiles, such as the porfile on my main PC as well as on my USB. I've noticed that when I go to get new mail on my USB, if I've already got it on my home PC then it won't show on my USB. I'd hate to have to copy the pc profile to the USB everytime I want to update my inbox. Plus if I receive something on PTB then my regular Thunderbird won't get it. These portable apps have been a lifesaver. Thanks for the effort and time.

If I receive an email I can reply to it. I can not however send a new email. I get an alert telling me to check my settings. I've quadruple checked and everything is the same as my desktop app.

Any ideas?

What's the best way to export mail and settings to either upgrade or to get ready for disaster recovery?

I'm only assuming that just saving a copy of portable thunderbird with settings on another medium, isn't the only way.

I modified the autorun.inf file provided to include "Launch Portable Thunderbird" in the list of programs that XP displays in the autorun window. It's one less click you have to make to run PTB!

[autorun]
open=PortableThunderbird\PortableThunderbird.exe
icon=PortableThunderbird\PortableThunderbird.exe
action=Launch Portable Thunderbird

I just started using Portable Thunderbird 1.5 and I love it. There are, obviously, a few quirks, but that's to be expected.

One, for instance, is that it doesn't seem to read RSS. It wont download the any new articles headers for some reason.

It this a known issue with all the portable Thunderbirds?

Am I the first person to have a problem with Portable TB? Is it that good?

On the support page, you say that you have made modifications so that Tb doesn't check if it is the default mail client. I am using Portable Tb1.5 RC1, and everytime I run it in this library, I get asked if I want to set TB to be the default client....

Anyone else have this problem?
