Where Is Mailbird Data Stored?
Mailbird stores local mail, indexes, and account data under the user Local AppData folder on Windows. The Store subfolder holds the message database files.
Last updated
Mailbird is a local client, so a copy of synced mail and settings stays on disk. That data is tied to the Windows user profile.
Close Mailbird before backup. Open database files can copy in an inconsistent state if the app is running.
