This is basically the change visible by git status if I drag and push a folder "Debconf Announce" from my T-Online account to my GMail account. > $ LANG= git status --short > Refresh index: 100% (622/622), done. > M "ImapMail/imap.t-online.de/INBOX.sbd/Mailings.sbd/Debconf Announce.msf" > M ImapMail/imap.t-online.de/INBOX.sbd/Mailings.sbd/Debian-Mails.msf > M global-messages-db.sqlite > M session.json > M xulstore.json > ??

I don't have any more POP3 based account for a long time so I can't readjust your specific case. But this shouldn't matter, the storage engine is the same, the mbox file format. I've played around with the behavior of .sdb folder together with .msf files also long ago. Basically you can copy the .sdb folder anywhere, you also need to create an equally named empty file .msf too then, the folder will already then be visible so far I remember, once you tell TB to compress the folder TB will recreate the index data for the folder and all emails are readable again. > Thunderbird apparently only accepts folders that it creates within an > IMAP mailbox.

The created folders/files doesn't know anything about the email server over them. > Perhaps at one point Thunderbird behaved better, but it's not doing > things all that well right now. I don't think so, the engine inside Thunderbird is quite old regarding to copy or move emails between folders and or accounts. There hasn't happen invasive changes in the near past. And your report about problems is the first to this topic since I've taken over the main maintenance for Icedove/Thunderbird. If this all isn't helpful for I'm sorry I can't help you more. To my experience issues like this are in 90% grounded on bad behavior of AddOns. Similar reported issues aren't reproducible by removed or deactivated AddOns and on fresh clean profiles. As I don't know about your potential AddOns I'm also not able to help on debug your issues. But also Yahoo did change their API often in a non RFC compliant way. But the last modification on this is long ago. The Debian wiki has some more hints about issue reporting, in case you haven't noted this already. https://wiki.debian.org/Thunderbird#Bug_Reporting_.2F_Issues There are also some hint on debugging activity, you will need to replace references to icedove with thunderbird mostly. https://wiki.debian.org/Icedove#Debugging -- Regards Carsten
