Prerequisites Before Moving MBOX to Zoho Mail Account
Zoho Mail is extremely particular about its security, so here are the steps you need to follow before you start adding a Zoho account to Thunderbird. Here are the things to remember:
Enable IMAP Setting
IMAP is the server on which Zoho and many other mail clients store their email. IMAP is very secure and syncs emails to other devices and emails rapidly.
- Reach “settings” in the top right section >> “mail accounts” under the mail section
- Once there, click on IMAP and enable “IMAP Access”. Generate an app password
profile>>> my account - Once there, go to Security >> App password >> generate new password.
- Enter any name and copy the password.
Generate an App Password
App passwords are one of the security measures used by Zoho to provide different passwords to log in to different clients, all operable from the Zoho mail client.
- Go to your profile>>> my account.
- Once there, reach Security tab >> App password >> generate new password.
- Enter any name and copy the password.
Thunderbird is Not Able to Fetch Details
IMAP has various IMAP port numbers and IMAP host IDs. If Thunderbird is not automatically able to receive details, then use the method to validate your details from the Zoho email client.
- Open Zoho >> settings >>mail accounts under mail section >> click on IMAP.
- From the table, copy the IMAP configuration setting.
- Add those details in Thunderbird accordingly.
- Finally, enter the password generated using the App-password setting of Zoho (refer to the “Generate an app password” section of the blog)
