Trident lets you import PST and EML files stored on your Mac so you can read and manage their contents directly inside the app. Imported emails are stored locally on your Mac and are never synced to Zoho's servers.
This is useful if you're migrating from Outlook, accessing archived emails, or retaining emails for legal or compliance reasons without adding them to your mailbox.
Note: This article explores importing emails to the Trident desktop app. Click here for the Zoho Mail web help documentation.To import an email file:
Click your profile image in the top-right corner of the app.
Select Settings from the drop-down menu.
Navigate to Mail > Import Email Files.
Click Import.
Browse for the file on your Mac and click Open.
If you imported a ZIP/TGZ archive, you need to select a folder location to extract the archive to and click Save. The file then will be imported to Trident.
If the import file is password-protected, you will be prompted to enter the password before the import begins.

Notes:
Click your profile image in the top-right corner.
Select Settings from the drop-down menu.
Go to Mail > Import Email Files.
Hover over the file you want to remove.
Click the More Options icon.
Select Remove.
Confirm the action by clicking Remove in the alert.

Notes:
Removing an imported PST file from Trident only disconnects it from the app. The original file on your Mac is not affected.
Removing an imported EML file from Trident deletes the extracted folder that was created on importing while the original ZIP/TGZ archive containing the EML files on your Mac is not affected.
Upon signing out of Trident, the imported email files will be removed and must be re-imported again on sign-in.
Right-clicking an imported file in the On my Mac section gives you options to rename and remove the file.

Tip: Explore all the available actions for managing your imported emails.
However, if Trident cannot locate an imported EML file, an error message will appear in that email’s detail view. It needs to be re-imported from the system.
