I'm using Thunderbird 149.02 to make a local copy of all folders, messages and attachments on my yahoo mail account. I don't yet see an obvious way to issue a command to Thunderbird to accomplish this.
I'm using export.imap.mail.yahoo.com as the IMAP server as some of the folders have >10000 messages (none have >100000 messages, and there is no significant real-time email arriving to the account while I do this procedure.)
In settings/offline settings I have "automatically follow detected online state" and "download messages for offline use when going offline [yes].
In account settings/synchronization & storage I have Disk space: Synchronize all messages locally regardless of age"; "to recover disk space, old messages can be permanently deleted..." I have "Don't delete any messages" and "Always keep starred messages"
With these settings, I've tried (from the main menu) File -> Offline > Download/Sync now, then "Download and/or sync..." I have selected Mail Messages, and the Select button takes me to a table where I have selected the main account folder and all sub-folders.
With these settings, Thunderbird appears to go through some of the folders and downloads messages from, them, and after a while says there are no new messages (I don't have the specific text, but it ceases interacting with the server". If I repeat the Download/Sync now procedure, it appears to download more messages, will continue for a while, then stop in the same way.
When I compare the size of Thunderbird's local account folder, it appears to grow after each of these iterations, but is (after half dozen cycles through this) has only reached about 2/3 of the total stoage size reported by Yahoo. While I understand the storage mechanisms would differ significantly between yahoo and Thunderbird, I don't believe I've found a single sure-fire way to accomplish what I set out to do in the first place (which is get a complete copy, through IMAP, of all emails, folders and attachments.
What am I missing?
Thanks,
