I only have a flat folder for my IMAP account Reproducible: Always Steps to Reproduce: 1. start to archive messages from an IMAP account Actual Results: Messages are moved under "Archives/<my account name>" folder. Expected Results: Messages are moved under "Archives/<my account name>/<year>" folders (supposed granularity is set to 1). Otherwise, messages may be moved unser "Archives", but Thunderbird uses "smart folders" to show messages grouped into years. I can create subfolders in my IMAP account, but not folders that can contain both messages and subfolders. I unchecked that option in the advanced settings of my account

Is your imap account gmail ?

Please note: if I create a folder "NewArchive/" that contains only subfolders and then I try to change my account options in order to map the archive folder to this new folder, I can't: the UI only lets me choose a folder that can contain messages, not one that can contain just subfolders.

Anything in Tools -> Error console ? Does it happens also in -safe-mode ?

Can you provide an imap log when you are trying to create the archive so we can see what your imap server is saying to thunderbird ? see https://wiki.mozilla.org/MailNews:Logging for instructions on creating the log.

What do you mean exactly with "when you are trying to create the archive"? This is what I actually did now: - I started Thunderbird - I already had a plain archive with many messages of different years, not grouped by year - archive granularity was set to 1 - I archived one message of 2010 from the inbox folder by pressing "A" over it - the message was moved to the Archive folder but no "2010" folder was created within the archive folder - I closed Thunderbird I suspect this may not be very interesting to you, since my server does not support folders with both messages and subfolders and my archive folder already contained other messages. Anyway, if so, please let me know exactly which steps do I have to do to provide you with a useful log.

That might be the rott cuase of the issue indeed.

(In reply to comment #7) > I suspect this may not be very interesting to you, since my server does not > support folders with both messages and subfolders and my archive folder already > contained other messages. Have you tried to delete the Archives folder, and re-create it as a folder that can contain other folders?

(In reply to comment #10) > Have you tried to delete the Archives folder, and re-create it as a folder that > can contain other folders? Please see my comment #2 and comment #7: my server does not support the creation of folders with both folders and messages, however I tried to create a new folder which accepts only folders (and so should be suitable to Thunderbird archive feature) but Thunderbird doesn't allow me to use it as an archive folder.

Basically, you change the folder type from "can have messages" to "can have subfolders"; this allows Thunderbird to create the year folders underneath the archive folder. I did not know that you can not choose a "folder-only" folder, but that's because when I tested it, I changed the folder type directly on the server, not from within Thunderbird, but Thunderbird still kept the folder selection. That might be a GUI-enforced limitation, rather than an intrinsic limitation, since for me Thunderbird still created '2011' and filed the emails there.

Hi Msquared, I did what you suggested: - I renamed my Archives folder to Archives_true - I created a new folder-only Archives folder - I opened Thunderbird - I tried to archive a message => when archiving, Thunderbird successfully created the year subfolder with the message in it! So the problem here seems that Thunderbird simply does not let you select a folder-only IMAP folder for archiving messages. I hope this is of any help to Thunderbird developers.

Do you still see tihs problem?

It's hardly impossible to say after more than five years, I don't have that server by hand to test any more.

(In reply to Wayne Mery (:wsmwk) from comment #14) > Do you still see tihs problem? With latest Thunderbird, I am still having that problem with imap-based archives. I have not yet tried the work-around mentioned afore.
