Instructions

Thunderbird doesn’t come with a built-in backup capability by default. The backup/restore options are significantly different from those of other mail clients.

.eml files are one way to backup your email messages:

Select the appropriate emails while still in Thunderbird. CTRL+A may also be used to select every message.

Your messages will be highlighted when you choose File >> Save As >> File.

Messages are saved.

I’m done now! An.eml file will be created to store your messages.

Drag and drop the.eml file(s) into an existing or new mailbox to restore the messages.

PROFILE

Additionally, Thunderbird stores data in «profiles.» These might serve as «backups.»

Select Go while still on the home screen of your Mac. the Option key down. Next, choose Library.

Open Thunderbird and go to Profiles. You ought to see a list of the active profiles on your device.

Copy the required profile(s), then paste or save them where you’d like.

Drag and drop your backup profile(s) to Thunderbird >> Profiles to restore them.

This information should be useful, we hope! Don’t forget that Media Temple didn’t create Thunderbird. If you need further help, we warn looking at the Resources link below, getting in touch with Apple Support, or speaking to a local IT expert.
