How to stop thunderbird from syncing a specific mailserver (imap)

emailimapthunderbird

Thunderbird 24.5.0

I have two mail accounts that I have deprecated, one I do not have login information for anymore, the other I would like thunderbird to stop downloading emails from (as they are forwarded to a current email address).

I have not been able to find a way to perform this.

I have tried going to Synchronisation & Storage > Message Synchronizing > Advanced and unselecting every mailbox tickbox under download as I thought this would stop them downloading (this has not happened).

I cannot find any other settings that can do this.

The only approach I can think of is changing the account information on the mailbox so that it cannot connect but I think this will lead to thunderbird prompting for a password every time. The only other approach is deleting the account and moving the mail somewhere else for storage, but I prefer having it in one place for a universal interface should I need to search old emails.

Does anyone know of a way to stop thunderbird synchronizing an account, without unintended consequences such as prompting for passwords?

As pointed out by Psychogeek the only solution I found was copying to a local folder and deleting the mailbox.

I had an unusual issue with a mailbox that I no longer had access to (a pop-up opened every time I clicked on one of the folders within it asking me to check my password/say it couldn't connect), as I could not copy the messages from within the mailbox (not sure why). This was circumvented with the copy-folder add-on which worked fine.

P.S. I have no idea what was causing the problem.
