I want Thunderbird to download all emails automatically, as soon as as it opens. I use to to back up a Gmail account, by scheduling it to open, download everything, and close, periodically.
As mentioned, I use Gmail, using the standard set-up in Thunderbird. It defaults to using OAuth and it works fine. The only sub-folders are the ones from Gmail, including a few tags I set up via the web interface.
The mails appear in the folder when I click on it, but their content is not downloaded to offline storage. It seems to refresh headers when I click on the folder. The not downloaded ones seem to be more recent, but perhaps not the very most recent ones.
For some reason when I open Thunderbird it doesn't download all emails, despite my settings. I have tried:
mail.check_all_imap_folders_for_newset to truemail.server.default.check_all_folders_for_newset to true- "Keep all messages for this account on this computer" ticked
- "Synchronize all messages regardless of age" selected
- In the Advanced menu for synchronizing, all folders are ticked
- "Check for new messages at startup" ticked
- In Folder Properties -> "When getting new messages for this account, always check this folder" ticked
- In Folder Properties -> "Select this folder for offline use" ticked
If I manually click "Get Messages" it does download the messages.
I have Thunderbird 102.14.0 (64-bit). It is the portable version on Windows 10.
I have checked the following questions, but none of them offer any ideas I have not already tried:
- How can I force Thunderbird to reload an IMAP folder structure from Outlook.com
- Thunderbird fails to download all new emails
- How do I synchronize all folders and emails of an IMAP account locally with evolution?
- Thunderbird won't download some emails
- Sync or export only Thunderbird account settings
- How can I force Thunderbird to download all emails by IMAP?
