[IMAP] Failed to LIST any folders - Error after last update

matula · November 16, 2024, 3:34pm

How to fix this error? Nothing was changed in the configuration, it appeared after the last update with one specific email account.

Same here.
I used the parameter --imap-list-ignore-path-starts-with “Virtual/” before to exclude some Virtual inboxes. After the upgrade I removed that parameter and instead started the new “Ignore Path”-feature in the UI.
However that also did not help. I only see my INBOX-folder. All other IMAP fodlers disappeared.
When trying to create a new folder it fails, saying that it is not allowed to create new folders in the “Virtual”-namespace.
This issue started right after the upgrade.

Same problem here with slightly different logs. This happened immediately after the latest update and none of my other email clients are affected. Outlook and android email clients are working fine.

I gave up and reverted back to version 10.0.3530 and it fixed the broken IMAP account.

kkwok · November 20, 2024, 8:10am

this happened to me too after last update. I tried deleting and re-adding that account but it didn’t help. And that email account has no problem with other mail clients on my other devices. This is exceptionally annoying as I can’t delete any of the emails (it will just stay there and give me an error that virtual mailboxes can’t be created), I can’t even send mails using that email because it can’t create a send folder. And I can’t send any emails to junk. When will this be fixed?

Gary · November 22, 2024, 4:09pm

This issue has been resolved, and a fix will be in the next release.

You can watch the Release History for when it is available. It will be the version after 10.1.4588
