Do I need to provide more information in the hope of getting a resolution to this?

This is the install.ini from the Macbook:

[6617B486D39D834F] Default=Profiles/xt1da1lu.default-esr-1 Locked=1

[712DAF5A23ABECDC] Default=Profiles/rn45ociq.default-esr Locked=1

This is the install.ini after its been copied to the Windows 11 Laptop and Thunderbird has been run for the first time:

[D78BF5DD33499EC2] Default=Profiles/fghoeb36.default-esr-2 Locked=1

[6617B486D39D834F] Default=Profiles/xt1da1lu.default-esr-1 Locked=1

[712DAF5A23ABECDC] Default=Profiles/rn45ociq.default-esr Locked=1

This is the profiles.ini from the Macbook:

[Profile2] Name=default-esr-1 IsRelative=1 Path=Profiles/xt1da1lu.default-esr-1

[Profile1] Name=default IsRelative=1 Path=Profiles/brkxhsos.default Default=1

[Install6617B486D39D834F] Default=Profiles/xt1da1lu.default-esr-1 Locked=1

[Profile0] Name=default-esr IsRelative=1 Path=Profiles/rn45ociq.default-esr

[General] StartWithLastProfile=1 Version=2

[Install712DAF5A23ABECDC] Default=Profiles/rn45ociq.default-esr Locked=1

This is the profiles.ini after its been copied to the Windows 11 Laptop and Thunderbird has been run for the first time:

[Profile2] Name=default-esr-1 IsRelative=1 Path=Profiles/xt1da1lu.default-esr-1

[Profile1] Name=default IsRelative=1 Path=Profiles/brkxhsos.default Default=1

[Install6617B486D39D834F] Default=Profiles/xt1da1lu.default-esr-1 Locked=1

[Profile0] Name=default-esr IsRelative=1 Path=Profiles/rn45ociq.default-esr

[General] StartWithLastProfile=1 Version=2

[Install712DAF5A23ABECDC] Default=Profiles/rn45ociq.default-esr Locked=1

These are the profile folders from the Macbook:

brkxhsos.default rn45ociq.default-esr xt1da1lu.default-esr-1

This is the profiles folder after its been copied to the Windows 11 Laptop and Thunderbird has been run for the first time:

brkxhsos.default fghoeb36.default-esr-2 rn45ociq.default-esr xt1da1lu.default-esr-1

It seems to me that, when run for the first time on the Windows 11 Laptop, Thunderbird is ignoring the files brought over from the Macbook and creating new files of it's own.

I will be very grateful if someone could tell me how to fix this problem.

Thank you

Mike

It's quite sad when you have a problem but nobody comes to your aid.

> I have made several attempts to move all the files and folders over but it doesn't matter whether I move them before I install Thunderbird or after I've installed Thunderbird and before I launch the program but every time I get invited to open a new account; I've even tried opening a new account and then moving the files.

You've provided us with raw information, but not told us about which data that needs to be moved, whether accounts are imap or pop, what exact step by steop process you used (one example would be enough) in attempting the move.
