Eudora OSE is Thunderbird 3 with the add-on Penelope. The result is you are upgrading Thunderbird 3 to Thunderbird Current. Given that OSE installed in it's own program files location I would assume it will run along with Thunderbird, but not both at the same time. File contention would make that very unstable.

If I uninstall Eudora OSE, will that uninstall delete its files? I would like to first uninstall Eudora OSE, then install current TB. Is there any risk to data from that sequence?

Also .... with my current Eudora OSE, I have a lot of messages with attachments. If I install to current TB, will those attachments still exist, or will they be deleted?

Also .... if the change to TB fails, would it be possible to uninstall the current TB and re-install Eudora OSE?

Thanks for your help.

why not just leave Eudora where it is. Then there are no what ifs.

Here is what I tried in an XP virtual machine under Win 7 Ultimate.

First, I set up Eudora OSE within the XP VM. I make settings etc.

Then, I uninstall the Eudora OSE from the XP VM.

Finally, I install the latest TB. The new TB has all the settings / attachments from the previous Eudora OSE installation.

Hence, it works.

This is obviously the solution to the problem.

Comments? Criticisms? Advice? Thank you.

Sorry to repeat the question ..... but..... has anyone tried the Eudora OSE to current TB route?

If not, would you expect it to work properly?

I need some reassurance that this method is likely to work, before I try it.

Thank you.

I have no idea what assurance you think you are going to get.

Eudora OSE is Thunderbird version 3 so you are upgrading Thunderbird 3 to the current version, of course everyone will expect it to work. Has anyone done it, probably not. The Thunderbird 3 line was superseded by the release of Version 5 in July 2011. Most folk that were going to upgrade would have done it more that 5 yeas ago to version 5 not version 45.

You have just done it yourself with the virtual machine. That says it all.
