It is important that the upgrade be done in stages and in sequence. Then go up three levels (Roaming folder) and copy the entire Thunderbird folder and paste it somewhere else. In Thunderbird, open Help > Troubleshooting Information and clickĪpplication Basic Information > Profile Folder: “Open Folder” will open the profile folder in use. However, if you install and start Thunderbird 91 out of the blue, trouble is expected to occur because the version is too open. In older versions, the authentication method is “Normal Password Authentication” and the application password must be issued on the Google Account side. Google’s 2-step authentication, “OAuth2” supported by older versions of Thunderbird, is not compatible with the current Google. In view of the latest security measures, I strongly recommend that you migrate to the latest version of Thunderbird 91. In short, I believe that Gmail will no longer be available in versions older than Thunderbird 68. Less secure apps & your Google Account – Google Account Help Google will end support for insecure apps (e.g., older versions of Thunderbird) on May 30 of this year. Is that correct? Or will all Thunderbird users have to upgrade to version 91 in order to make Gmail work? I don't know how long a OAuth2 token is supposed to last (supposedly depends upon the email provider) but they normally get transparently renewed.Just as a point of clarification, older thunderbird versions eg from 36 to 78, already have OAuth 2.0 so they won’t need to do anything. What is the authentication method set to in each account? I'm wondering if you're using OAuth2 authentication and having problems with the token being renewed, perhaps due to cookies. What Linux distro are you using? Are you using a Thunderbird package provided by the distro or a generic Linux build downloaded from the web site? You can get help for either in this forum, I'm just wondering if there is some tie-in to distro updates etc.Īre you using any other email clients, such as one on a smartphone? If so, do they have the same problem? Your user agent string mentions Linux x86_64. Has your webmail (log into a web page using a browser to read mail) password stayed the same and not had any problems when this occurs?ĭoes this occur about the same time as you using a cleanup tool such as CCleaner?


Do they just disappear and you get a normal prompt for a password or do you get a error message about your passwords expiring?
