Unable to get quota information, server responded with an error

Hello there. I am getting this error:
[IMAP]Unable to get quota information, server responded with an error: Client tried to access nonexistent namespace. (Mailbox name should probably be prefixed with: INBOX.) (0.001 + 0.000 secs)…

Also I am getting emails with links that I have to confirm my email address and password to get my incoming messages on hold. Anybody could help?

This could meen that the server doesn’t follow specification.

Without seeing IMAP logs, there is something you can try. Go to Menu > Accounts and click on the Diagnostics tab for this account. Enter the following in the Advanced Options Parameters

–imap-inbox-with-namespace

Then click on Save & Close.

Thank you. But I cannot see any difference. There is still an error

Then that is not the cause.

Can you please contact me directly on [email protected] and I will give you some instructions on how to generate specific logs so we can see what is happening.

I have the same error message and the advanced parameter does not help either.

Good news is: This does not happen when viewing the quota for a specific folder. For me the error only occurs when attempting to view the account quota by right clicking the root account node and not a folder.

here is a stack trace:
