Dear community,

I have been using Thunderbird for many years and simply love it. (Now running v. 91.9.0, 64-bit for Mac-OS monterey v. 12.3.1).

After having used G-suite gmail with my own domain name for years as well, I am now forced to upgrade to a google business offering or take my domain name email somewhere else :-(

So I signed up for an alternative provider, and have copied a couple of folders to the new email-account using Thunderbird. This works like a charm, but what happens when I copy over the AllMail folder? I believe I will then duplicate all the emails copied from the folders?

Is there a smart way of migrating from gmail to another imap-provider using Thunderbird which will take into account google obscure way of labelling emails? Or is there another way of migrating away from gmail?

Any help will be much appreciated.

Thanks, Fred Gjoertz.

I suggest you keep doing what you're doing: copying the folders you need. You then don't need the Allmail folder.

Hi David,

thanks for replying. As not all the emails are in folders and I want to have access to allmail as an archive, your suggestion would not be an ideal solution for my challenge.

br, Fred.

I have experimented with Google takeout in order to see if this could be a solution to my challenge. However, google takeout creates an inbox which includes all the replies sent - and contains almost twice the amount of emails as my original inbox.

On another note, I will try to copy all the folders (using Thunderbird) and thereafter run the extension "remove duplicate messages" (https://addons.thunderbird.net/en-US/thunderbird/addon/removedupes/). This may very well be the solution.

Who is your new provider? most of them offer some form of IMAP transfer or import. Google certainly offer a takeout service that provides the contents of the account as a series of mbox files. Perhaps you new provider offer a way to import those to the server if the do not offer something more robust.

While there is a cottage industry of migrating mail from account to account with a mail client, it is slow, buggy and prone to error. Data loss is not uncommon.
