Common Errors During Thunderbird to G Suite Migration
On Windows look in %APPDATA%\Thunderbird\Profiles. On macOS use ~/Library/Thunderbird/Profiles. Pick the folder ending in .default.
2. “Authentication failed” on Gmail
Gmail rejects regular passwords for third-party clients. Generate a 16-character App Password from your Google Account security settings.
3. Labels appear nested differently in Gmail
Thunderbird uses true folder hierarchy. Gmail simulates folders with labels. Pre-create the target label tree in Gmail, then map manually in the migrator.
4. Upload pauses at the Gmail import threshold
Gmail throttles inbound IMAP at roughly 2,500 messages per hour. The migrator retries automatically once the rolling window clears.
