Hello,

"Your Thunderbird profile cannot be loaded. It may be missing or inaccessible".

New installation of Windows 11. Installed Thunderbird 102 and did some setting up. I must have made a bad choice as I now get the above error message and cannot open Thunderbird. I have uninstalled TB and reinstalled but to no effect.

Help and advice very gratefully received.

Regards

The simplest solution here is this: - uninstall thunderbird - in windows file explorer, locate c:\users\<yourid>\appdata\roaming\thunderbird and delete the folder. then reinstall thunderbird.

What you apparently did was rename the profile folder or moved it. Thunderbird looks at the profiles.ini file in the above-mentioned folder for the name and location of profile. If the file isn't found, you get that error message.

Thanks David,

I was too clever by half and copied the Profiles folder only. Now in much better position than I anticipated. Inbox and all sub-folders restored.

Best wishes
