K-9 Mail does not auto-sync in the background?

Hi, I’m using K-9 mail v.14, and I can’t seem to get K9 to auto-sync my email accounts in the background. Plus (2nd issue) when I manually refresh my “unified account”, the “non-primary” folders of my accounts do not update. I need to manually go into each folder and update them one at a time…

When I go to Settings > [One account] > Fetching mails, I have the following settings:

  • Local folder: 2 500 mails
  • Sync emails: latest week
  • Fetch mails until: every size
  • Sync frequency: 15 min.

The K-9 app on my phone has the “running in the background” setting enabled.

Do you know how I can solve my two issues?

if you go into the particular account, choose the menu, then select Manage Folders, you should be able to set each folder to sync, or enable push, or notify, or unify. Do you have that sync option set for your non-primary folders?

I think if you create a new folder on the server, the default behavior in K9 is to not sync. You’ll have to enable it.

Indeed it seems to work!

And you correctly assumed that I created these folders on the servers, not in my K9 app.

If you have a solution to enable sync for a lot of folders that would be great for future users! I had to enable sync for every folder.

Good, glad that worked.

Actually, you can only create folders on the server side. It likely prevents a collision and potential resolution case if one on each side with the same name is created.

If you want the devs to make a multi-folder select functionality, drop a github issue in the project (or thunderbird mobile project). I can’t think of a clean way to do it, as any of the folder options could cross-apply. And hopefully setting the options is not a frequent or even repeat event.
