I have a Gmail account in TB2 that I set up with POP. I'd like to change
it to IMAP.

That's easy to do with Gmail but is there any (hidden) configuration
file that tells TB which protocol to use and that can be changed?

I'm aware of the fact that Imap and Mail (POP) are different Windows
folders in the Profile hierarchy. Is there something I can do there?

Thanks.

I would say and think that differently. I would say and act to 'create
a new email account which is - turns out to be - an IMAP' specifically a
gmail one.

Tbird 2 gives you options to create an email account or to create a
gmail account (in the new account wizard). My approach would be to
create an email account, not a gmail one. In tbird2, creating a gmail
account assumes pop; whereas creating an email account provides an
option to create an imap or a pop account.

It is considerably easier to control the account creation process in
tbird2 than tbird3.

If you start with email, it will be easy.

If you don't think of changing, but instead of creating a new account, I
think it will all be straightforward.

Well, that shows how different we think, Michael!

The email account I have is many years old and "well-developed" in that
it has dozens and dozens of folders and subfolders in Thunderbird, and a
like number of labels in the Gmail counterpart.

Since it's easy to change the Gmail part, I'm looking for an easy way to
change the TB part.

But I appreciate your input. :-)

Well, if you were to change the account to IMAP, it wouldn't matter what
folders you had originally within TB, for TB would automatically take on
the folder (label) structure of the underlying Gmail account.

The folders and subfolders in tbird consist of databases which carry
foldernames which you have created and database characteristics which
stem from the name of the account which they came into. Those are not
the same as imap folders.

The folders in gmail *will* correspond to the new imap account.

Perhaps you misunderstand me and think I'm saying that the gmail address
is going to change. That is not so.

But the tbird pop inbox folder will not be the same inbox as you will
have with your new imap account - and/but your new imap account will be
able to 'adopt' all of those gmail folders.

You will 'change' the tbird part by creating a new imap account in
tbird. And IMO you would do it most easily in tbird 2 by creating a new
email account, not a new gmail account.

You can't switch the existing account from POP to IMAP, you have to
create a new account configured for IMAP after which you can transfer
messages from one account to the other by drag-n-drop. I've done this a
lot on my own server to test it and it works here.

I was afraid of that, but let me ask this: When I go to Account Settings
> Server Settings, it reports that the server is either IMAP or POP3.
TB obviously gets this information when one creates an account, but
where does it store it?

I see that prefs.js has the information about whether an account is
POP3, IMAP or NNTP. Maybe I'll play with that a bit.

You can't get proper IMAP folders by creating them yourself except as
you relate to - cooperate with - the configuration which is going on
between the IMAP client and the IMAP server, which client created a
(new) imap account.

A non-imap folder is not an imap folder. I can't even imagine
handcrafting the result you should obtain by properly creating a new
IMAP account.

Perhaps you should read some about what IMAP is.

http://en.wikipedia.org/wiki/IMAP Through the use of flags defined in
the IMAP4 protocol, clients can keep track of message state; for
example, whether or not the message has been read, replied to, or
deleted. These flags are stored on the server, so different clients
accessing the same mailbox at different times can detect state changes
made by other clients. POP provides no mechanism for clients to store
such state information on the server

The info is stored in prefs.js .. Haven't tried it but you may be able
to change the configuration there .. BUT .. make a B/U of prefs.js first!!!!

I haven't tried it but if the account can be changed in the prefs.js
file then when restarting TB, the IMAP folders may be there and then
subscribed to. The positive indication that it worked is you will see
"subscribe" in the list of folders where it's not there in a POP account
setting. I may fiddle with it, I have enough throw-away accounts to
spare and I run my own server as well.

Solution:

Close TB, locate prefs.js and make a backup. Edit the file, look for
your account and the line "type,pop3" .. change pop3 to imap. Save,
restart TB. Your account is now IMAP .. I tested this on a POP3 account
and it worked flawlessly.

Since IMAP is configured on the "server", yes you can change from POP3
to IMAP by editing the prefs.js file. See my latest reply to Pete about
this. I tested it and it worked 100%.

I did .. but I tried it and worked AFTER I posted that. Did you see my
reply where I said I tried it?

aren't we safe assuming he is using the /same/ client to access both

Jay, your info looks good to know.
Looks like Pete is trying to find his (sic) subfolders, other folders,
which aren't listed in prefs.js (I have several myself). I think what
he wants is listed within his profile in the pop server folder, 2 files
each for me - linux calls them mailbox file and a related .msf file.

Super! Did any of the accounts you did this with have multiple
user-created folders and subfolders? Any of them have names starting
with one or more spaces?
