I am available.

Which version of Thunderbird are you running now? At the top right of the Thunderbird window, click the menu button ≡, then select Help > About Thunderbird

128.5.2 esr (64bit)

Good. What is your current profile? Please state the full path and the name of the profile folder. Instructions in the link below. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_how-do-i-find-my-profile

C:\Users\Alan Macleay\AppData\Roaming\Thunderbird\Profiles\exm3wxnn.default-esr-2

C:\Users\Alan Macleay\AppData\Roaming\Thunderbird\Profiles\exm3wxnn.default-esr-2

That's the wrong profile. You want the nn70px6e.default-esr profile.

At the top right of the Thunderbird window, click the menu button ≡, then select Help > Troubleshooting Information. Locate the line 'Profiles', and click the link 'about:profiles'. This will open a new tab listing all profiles known to Thunderbird.

Please post a screenshot showing all profiles in that tab.

Thought you might like to see my new Profile is alongside the previous two.

This isn't what I asked you to do. Please follow the instructions given above.

Sorry. It is taking a long time to upload. Sending this hopefully to close the upload and will try again

Here it is

For the default-esr profile (the top one in the screenshot) click the 'Set as default profile' button.

Restart Thunderbird.

Verify that you're now running the default-esr profile: Please state the full path and the name of the profile folder. Instructions in the link below. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_how-do-i-find-my-profile

If so, verify that email messages and address book contacts are up to date.

Great. I am now running my default profile. I have all my messages and address book, and Contacts up to date. What does this now mean?

D:\Thunderbird is an empty folder. Not sure if the Mail folder on D: is being used. It seems the Profiles and abook is running on C:

What does this now mean?

Basically you're done now. There is just some clean-up work left to do. Try not to mess it up again, and make sure to create backups of your profile on the C: drive, as well as the mail store on the D: drive on a regular basis.

D:\Thunderbird is an empty folder.

Wrt clean-up:

• you can remove the other profiles which are now all non-default ones via about:profiles. Create a backup before removing them if you think there is something in those profiles you want to keep.
• You can also remove the folders underneath

C:\Users\Alan Macleay\AppData\Local\Thunderbird\Profiles, except the one being used by your default profile - that's the one starting with nn70px... There is nothing to backup here, as this is just cache data.

Good luck.

Thanks. Messages are going to D: wrongly named D:Thunderbird Profiles. Shall I change this name to Thunderbird Mail? If so how do I change the pointer? Please note abook is still only on Drive C:! I wanted originally to move that to Drive D:. Whilst Thunderbird is restored, it is restored to exactly how it was when we started. With Profiles renamed Is it possible to move the actual Profiles, including the Address Book to D:\Thunderbird?

Messages are going to D: wrongly named D:Thunderbird Profiles.

This is the setup you created. It's not the most elegant way to do it, but it works. I've suggested before to leave it like this, and that still stands.

Whilst Thunderbird is restored, it is restored to exactly how it was when we started.

Not exactly. We've cleaned up a lot of the mess you created, including duplicate Thunderbird installations, various remnants of failed attempts to move the profile, and various old profiles. And you should have gained some more free disk space on the C: drive as well. So once again, this setup works, just leave it alone now.

With Profiles renamed Is it possible to move the actual Profiles, including the Address Book to D:\Thunderbird?

While this is possible, it is a non-trivial process. If you attempt this, I'm certain you'll mess it up (again). Feel free start a new support topic, may be someone will step in to help. But that will not be me.

I have tidied up most of the debris from what we have done, but need, eventually, to clear up the back up files. I had previously earlier backed up to a remote hard disk. Please can you help with my previous questions, indeed with what I had originally asked for help with?

I have now tidied up the debris, and have been looking at doing a fresh install of Thunderbird, as advised, using the custom installation on Drive D:. I am presuming now we have cleared away that misleading stuff, I suspect I will now be able to have all of Thunderbird on the same drive, having them split across two drives did concern me, I think I do need some help, or guidance before I start. Notably dragging Profiles and Messages together. I note there are two versions, 115 and 128. What is the difference, aside from different frequencies of updates, that I need to be aware of? Once installed can I then presume anything else of Thunderbird on C: can just be deleted?

Regards,

Alan
