**Troubleshoot Mozilla thunderbird Not Receiving Email Issue**

By now, you must have a considerable understanding of this issue. Here are some proven fixes to employ when you are facing issues with sending and receiving emails.

**1: Check If the Server is Down**

One of the highly prevalent causes for this email issue is the server being down. So, you should first check the status of the email account server and verify whether it is really down or not. It’s wise to examine the Yahoo Mail server status. It’s because it hosts the Mozilla thunderbird email domain. You can easily check whether the server is down or not by going to sites such as Sitdownforme and DownDetector. If you find that ‘Server is down for everyone’ on these websites, you have no choice other than to wait till it starts functioning again. However, if you see ‘Server is working fine’ displayed on the site, it implies that the problem is at your end. Proceed to the other fixes mentioned below if this is the case.

**2: Delete the Wrong Email Filter**

Email filters filter the messages your email receives. They then direct them towards the desired folder. These filters automate this process and help you keep your account organized. However, the situation turns the opposite if you mistakenly create the wrong filters. Incorrect email filters will make the emails for a specific filter be received under another filter. So while you are creating them, be very cautious about this fact. If you are having problems receiving emails, it’s likely that they are in another folder. In case you have created the wrong filters but are unsure of how to correct them, go ahead and simply delete all filters. Now check if you can receive emails on your Mozilla thunderbird email account.

**3: Check If You Have Blocked the Sender or Are Being Blocked**

Another common reason for Mozilla thunderbird email not sending or receiving messages is blocked addresses. If you have blocked the person who has sent you the message, you won’t get their emails in your inbox. So, examine the blocked list and unblock the person from whom you need to receive the message. Similarly, ask your recipient if they have blocked your email address. If they have, tell them to unblock it so they can receive your emails.

**4: Check the Network Connection and Clear Cookies**

A simple fix for when you find your Mozilla thunderbird not sending emails or receiving them is to examine the network connection and clear cookies. Your internet speed must be stable so that your email loads speedily. Excessive cache and cookies in the browser need to be deleted so that your email account can function efficiently. Just head to the ‘Settings’ of your browser and delete all history. You will see an improvement in the performance of your Mozilla thunderbird email.

**5: Fix the Forwarding Problem**

Many people find that they can’t receive Mozilla thunderbird emails or send them because they have enabled the forwarding settings. You must examine these settings in your Mozilla thunderbird email account. It is likely that you have switched on the forwarding settings and don’t remember about it. So, it is better that you log in to your account and turn it off.

**6: Check How Much Storage Space You Have**

If you have been using your email for a considerably long time, you may have run out of adequate storage space. If this is the issue, it’ll be difficult for you to receive new emails. Not only from blocked addresses, but you will also not receive emails from those you haven’t blocked. There’s a specific storage space that every Mozilla thunderbird email account has. When you use it fully, you won’t be able to receive any new emails. To fix this problem, delete a bunch of older emails. Then, send an email to yourself from another email account. If you can receive it, it means you have freed up space. But if you still cannot receive the email, you need to free up some more space.

**7: Check Whether You Are Using the Old Server Address**

Sometimes, you’ll find Mozilla thunderbird.net not receiving emails or sending them if their server address is changed. It’s common for email services to change their addresses without notifying their users. Suppose the Mozilla thunderbird email account has changed its server address and you are still typing the old address. In that case, you’ll find it difficult to carry out email communication. The best method to fix this email issue is to connect with your network administrator. Ask them to give you the new address so you can sign into your account.

**8: Update Your Email Client or App**

If you are using an email client like Outlook or Thunderbird, ensure that it is updated to the latest version. Outdated email applications may not function properly with new security protocols, leading to issues in sending and receiving emails.

**9: Disable Antivirus and Firewall Temporarily**

Sometimes, security software like antivirus programs and firewalls may block Mozilla thunderbird email from functioning correctly. Try disabling them temporarily to check if the issue is resolved. If so, adjust the security settings to allow email communication.

**Additional Preventive Measures for a Better Email Experience**

•	Regularly update your account credentials and ensure their security.
•	Use a strong, stable internet connection for sending and receiving emails.
•	Periodically update your email application or browser to the latest version.
•	Avoid downloading suspicious attachments or clicking on unknown links.
