I use Thunderbird 115.6.1 on Windows 10 with multiple email accounts. One account closed several years ago, so I disabled syncing with the server but I kept my messages local so I could continue to read them (and reply from other accounts). This is an IMAP account but I was basically using it in offline mode. A few weeks ago, Thunderbird started trying to reconnect to the account automatically. I had turned off "check for new messages at startup", "check for new messages every X minutes" and "allow immediate server notifications" so I don't know why it keeps trying to connect to the server. Now I can't read the emails in that account. The headers are visible in my inbox but when I try to open a message, it's blank; it tries to connect to the server. I contacted the server host (a university) and they say they no longer have a copy of my emails. Is there any way to retrieve my messages from my local profile? ThanksS!
