Not migration, Thunderbird. The application checks for updates and auto updates itself if a later version is found.

Thanks for reply, well ok, but I had not yet setup an email account prior to copying the only Mail folder to the Profile. The updating msg did not occur during initial first open of fresh installed TBird. I then chose option to setup account Later and closed TBird. Then copied in the backed up profile. The copied profile had update UNchecked (as it still is in Acct Settings).

So then are you saying that no matter what, every time one installs TBird from whatever version installer, it updates to a newer version? If so then it did so even though the profile settings said otherwise since they were in place prior to 2nd start of TBird which is when the Updating msg occurred?

When Thunderbird was installed it's likely to have created a default profile and that profile would auto have the update selected.

After exiting Thunderbird, you then copied over the old profile, but how did you do this as there are various methods.

• Did you access the 'Roaming' folder and delete the 'Thunderbird' folder and then past the copied 'Thunderbird' folder into the 'Roaming' folder ?

• Did you access the /Roaming/Thunderbird/'Profiles' folder and paste the copied old profile name folder into the 'Profiles' folder ?

• Did you access the /Roaming/Thunderbird/Profiles/<'profile name' >folder - delete all the contents and then paste all the contents - all files and folders - that were contained in the old profile name folder thus keeping the default profile name folder but replacing all it's contents ?

After copying over the old profile, you started Thunderbird, but which of the following methods did you use?

• Did you start Thunderbird using the 'Profile Manager' so you could choose the default profile on which to use upon start ?

• Did you start Thunderbird, then create a new profile to point to the copied profile and then set it up as default profile ?

• Did you start Thunderbird, then add mail accounts, then accessed the Account Settings > Server Settings and set the 'Local directory:' to point to the relevant folders in the copied profile ?

• Did you start Thunderbird as normal and all your old profile folders showed immediately?

Thanks for the reply, sorry to be late getting back. I will try to answer your excellent questions with the below summation. I installed an old saved version Ver 52.8.0 of Thunderbird on new Laptop and started Thunderbird, choosing to later create Email account data. Stayed in long enough to set few things including Auto Update to OFF and then exited (didn't want any surprises right now). In a file manager I looked at the newly created folders and files in the TBird install. It did have a Profile with some files in the Profile root folder. But did not yet have a Mail folder.

I then (in file manager) copied the all the contents of my Postbox 3.x Profile (the Profile root folder files and Mail Folder, did not include minidumps) to the new created Thunderbird Profile overwriting everything with same name. (Postbox has similar mbox, msf file formats)

Then restarted Thunderbird and Popup came up saying migration updating or something like that. When it was done all my old Postbox email folders and email where there and all my account settings also came up good. I did not have to setup any new account or even give a login password. Everything came over as it was in my old Postbox profile. I looked in TBird Options, Advanced, Update it had a selection dot by Never check for updates (not recommended). And in reference to this last sentence above, I need to make a correction to my original question wherein I said looking at new Acct settings that came with copied Postbox Profile it still had the box by Check for new messages at startup UNCHECKED. All my Mail and settings were there and functioning. That was my confused error of presentation, when I meant to type the Options->Never check for Updates. I apologize for my sloppiness therein. [ This is in fact the case since my old Postbox profile still has the [ ] Check for new messages at startup UNCHECKED, but that's not the same setting premise as software updates. I also leave this one unchecked since I like to choose when I download from server (not on startup). I'm still using my old Postbox to download from the Server until I decide on a new Email app. ]

But in any case everything came up the same in Thunderbird just fine. Because I wanted to check Thunderbird out a bit before I started taking stuff off the server with it. So I must commend TBird on it's ability to absorb a moved Profile since that is important to be able to copy one's past Emails to a New app.

The only thing I'm curious of here is why it updated to ver 60.9.1 (32bit). Again I realize updates are sometimes inevitable but I like to be able to decide on my own when that it is with any app or Windows itself.

I believe the following occurred

Installed Thunderbird, ran once and set up Auto Update to OFF Exit Thunderbird.

Then you accessed profile and performed an import overwriting various files. Maybe the Auto Update was temp disabled until the newly updated file was opened, but the updater was working before the profile was launched.

When you Started Thunderbird... It's possible at this point there was another updater program on computer which detected an update being available and it overrode any settings you had chosen because at that point it had not fully launched Thunderbird. This is well known to be a problem.

Windows OS does have this ability - check out the settings:

By the way, should you want to perform updates to use a product that is not so old and less secure, I would strongly advise you do this: 1. make a backup of the C:Users/username/Appdata/Roaming/Thunderbird folder before any updating because from 68 onwards it's not as simple to just download a previous version. https://support.mozilla.org/en-US/kb/dedicated-profile-thunderbird-installation 2. download and update to each major release - see info here on what occurred in those releases: https://www.thunderbird.net/en-US/thunderbird/releases/ So you would update to 68 then 78 then 91 and finally 102 do not try to go straight to a recent release because in the various versions there has been much in the way of updating to use different file formats in particular the address book and calendar.

Lots of things have changed since version 60* and there is likely to be a complete major rewrite of code and design in a few months time for the next major release.

RB2124, Good point, possible, since TBird did have the Option setting of Use a background service for updates. However I checked just now and the MS Store setting is OFF. I've never done anything with MS Store nor do I login into an MS account on startup.

RB2124, Those are some excellent links that I'm going to read up on. At this point I will keep using Postbox and maybe even install the newer version of it. I own a lifetime Update license to Postbox but just preferred the older version interface better. But in spare time I will uninstall TBird completely and then check each item carefully on reinstall just to solve some curiosities. I've always liked TBird except for a few interface items have kept me from using it for my main POP3 client.

There is one more question at this point if you would be so kind as to comment on it. I've read that in the future TBird is thinking of leaving the mbox format and going to SQL (or possibly SQLite) for it's Mail db files. If that happens what issues might be on the horizon for moving previous TB mbox profiles to the new Profile? Also wondering whatever version/type of the SQL db files if they might have viewable access with an app like SQLite in a case of them not importing into whatever email app the future might hold?

Thunderbird has moved all it's address books from MORK (.mab) over to SQLite.

But I'm not aware of any intention to leave mbox format for mail files. Personally it would be a pain in the proverbial as mbox text files are so easy to salvage emails providing you do not allow them to get too large. I never allow mine to get larger than 200MB. There is the alternative Maildir setup where each email gets stored as a separate file, but there has always been a certain amount of caution with this method. Probably because it has not had as much testing/ work etc.
