    Thunderbird Profile problems

    Windows v 1903

    I have been running Windows 10 for about 3 months now. And in that time I have used Thunderbird for Email. Now, suddenly, it demands that I set up a Profile. But it won't let me set one up. There is no way I can produce a new profile or get one to "stick" in the Profile's folder.

    I can't access Thunderbird in any way, I can't even tell you what version of the app I'm using as it won't let me in.
    Can anyone help?

    Thunderbird problems

    Right, so my gf's dad tried to back up his mail from Thunderbird to a network HDD by changing the location of the local folder for all his accounts, which is like 3 or 4. Now, none of his mail or accounts show up in Thunderbird and they aren't listed on the network drive. I was able to locate all the mail in its original location in AppData, but I don't know how to get it back to the way it was. Any ideas would help, thanks in advance.

    Windows Live Issue & Thunderbird folders

    Hi Allan

    Windows Live Mail

    Could be a corrupt WLM database. I suggest you try the following (assuming you use the default location of the WLM data).

    Warning - this process will remove your email accounts and all emails in the mail boxes and Storage Folders

    • Close Windows Live Mail
    • In File Explorer, navigate to C:\Users\<yourusername>\AppData\Local\Microsoft, locate the Windows Live Mail folder
    • Make a backup of the Windows Live Mail folder on a flash drive or somewhere else. (With this backup you will at least be able to view individual mail messages)
    • Delete the Windows Live Mail Folder
    • Restart Windows Live Mail - it should behave like when it first installed, requesting your account details etc.


    Which INI files did you rename? If you didn't rename any ini files in the folder C:\Users\<yourusername>\AppData\Local\Thunderbird\Profiles, do the following:

    • Close Thunderbird
    • Make a backup copy of C:\Users\<yourusername>\AppData\Local\Thunderbird\Profiles
    • Delete the folder
    • Uninstall Thunderbird
    • Reinstall Thunderbird but don't start it
    • Restore the above folder fro the backup
    • Start Thunderbird.

    If that doesn't work try playing around with the Thunderbird Profile Manager

    • Hold Windows key and tap R, enter the following exactly with quotes etc. in the "Open" box, OK
    • "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe" -P
    • If you see "Default User", select it and tick "Use the selected profile without asking at startup"
    • Click Start Thunderbird and see if your profile (messages, accounts, contacts) appears
    • If not, close Thunderbird, Start the Thunderbird Profile Manager again
    • This time click "Create profile" to start a wizard, click Next
    • Enter a profile name, click Choose folder
    • See if you can locate your profile folder, select it. Start Thunderbird
