The Eternal Sync Bug

The sync bug is unrelated to anti-virus, I am on Linux, and don’t use anti-virus software, yet the eternal sync bug is there.

scanning message…

forever green spinning circle…

ubuntu 20.04

kill the process and re-start mailspring would help.

why this bug is unfixed until now…

I have the same issue.

I have a lot of gmail or hotmail accounts in Mailsprings, some with 10 000+ emails, and they all sync fine except one. That one account get stuck while attempting to get my Archive folder, which holds ~975 emails. It’s a Mailo.com account, using IMAP.

I tried Mailspring on Linux and Windows 10 and the issue occurs in both platform.

When using Evolution on Linux, I can sync that account without issues, including the problematic Archive folder and its ~975 emails.

Same issue here on macOS (see client and server logs below). Tried from two different computers and one account (the same on both computers) does not sync . It keeps saying “encountered an error while syncing”… I have to manually hit try again every time. I’m attaching some logs. Another account on the same server syncs fine although that one has fewer emails.

I’ve got the same issue. Scanning is stuck at 3% on my outlook.com account. The other accounts (gmail, yahoo…) work fine. Recreated cache multiple times, deleted appdata, disabled virus scanning.
On first glance mailspring seems to be much faster than thunderbird in every aspect! Thank you for the great work so far.

Windows 11
Mailspring 1.10.3-a476c230

Thank you!
