Mozilla Thunderbird is a desktop-based email program that comes with various useful and advanced features, such as tabbed interface, automatic spam detection, and advanced filtering tools. If you’re facing issues when downloading or viewing email messages in Thunderbird, check the account settings and the options twice. If the problem remains, either reinstall the Thunderbird program or get in touch with professional by dialing the Mozilla Thunderbird support phone number. Otherwise, follow this troubleshooting procedure:

Account Settings

Select the ‘Account Settings’ option via the ‘Tools’ menu to open the settings of your email account. On the next window, you will find all of the options associated with each of the accounts like the username and password to sign in, the remote server settings, and where email files are retained. Sometimes, the default settings should work correctly. If you have any doubts, then see the details with your web mail service provider or try to delete the account and add it again to check if the issue is resolved.

Email Locations

Ensure that you haven’t configured filters that are removing the messages from the mailbox before having any chance to read them. To check the filters used in the account, choose the ‘Message Filters’ option via the ‘Tools’ sub menu. Additionally, ensure that your messages aren’t being downloaded by another email program on a different computer or from a webmail client if you’re using the same account from somewhere else and selecting to remove the messages when downloaded they won’t display in Thunderbird. If you’re trying to open an Internet-based service like Gmail, access its Web interface and check that you have correctly enabled access to the specific folders.

Error Messages

If Mozilla Thunderbird is encountering an issue opening the email account instead of just not locating something to download, you might see an error on the screen displaying further details to help you fix the issue. Choose the ‘Help’ tab, and then ‘Help Contents’ option from the program menus to access the Thunderbird Support portal in the default Internet browser. Continue with the troubleshooting links or use the Search box at the upper of the window to locate resources associated with the problem.

Email Provider

It is likely that the issue might be caused by the webmail service provider instead of Mozilla Thunderbird. You can check that or prevent it from downloading the emails to an alternative email client like Windows Live Mail or any other Internet-based email service. Inspect using the email service provider through the phone or go to the official support web pages of the site to check if the webmail service has listed any issues. Some webmail services provide help pages offering troubleshooting guide and even detailed setup directions for setting up the email account with various clients, such as Mozilla Thunderbird.

However, if you are continuing to face issues and you’re unable to download emails to Mozilla Thunderbird, it’s highly recommended to call on the Thunderbird email customer service number to get all your knotty glitches resolved without any hassles.
