Can’t Send Attachments in Yahoo Mail? 10 Methods to Resolve the ‘Yahoo Mail Can’t Attach Files’ Issue

It’s been 25 years since Yahoo Mail launched. It’s been around forever and is everyone’s favorite email service to send and receive emails. However, while it has always been at the forefront of providing cutting-edge technology and enhancing the user experience for its users, it is not without its flaws. Time and time again, people face problems with their Yahoo Mail and this time ‘Yahoo doesn’t send emails with attachments.’

Despite features like automatic mail forwarding, some users are unable to send attachments from their Yahoo mail. This problem has recently become more common and more and more people are encountering it.

The reason why you can’t add attachments in Yahoo Mail can be due to any number of reasons. This could be a Yahoo technical issue or simply a case of the filename not being in the correct format.

Regardless of the cause of the problem, the solutions are simple. So, if you are unable to attach files in Yahoo Mail, immediately see the article below which lists 10 simple methods that can solve this problem immediately.

Check file name

If you’ve added special characters like slashes, dollar signs, hashtags, asterisks, etc., this is why you can’t send attachments in Yahoo Mail. This is because Yahoo doesn’t accept files with special characters in the name.

So if your attachment’s name has such a character, rename it and then retry uploading it to your email. If you don’t see the Yahoo Mail attachment’s exclamation mark next to the filename, you’re ready and able to send an email with an attachment.

Additionally, you cannot submit files with an unknown file type/extension or an extension not recognized by Yahoo. It will mark them as malicious to prevent any virus transmission. To prevent this, you can try sending files in commonly used formats like .pdf, .png, .txt, etc.

Pay attention to the file size

As is the case with any other email service provider, Yahoo Mail also has a limit on the size of files you can attach to emails. In Yahoo, you can attach files up to 25 MB in total. So, if you attack the file with an email that exceeds the specified limit, then Yahoo Mail will not attach the file and will not allow you to compose or send Yahoo email.

To work around this issue, you will need to reduce the file size. You can do this by using any of the free online tools to compress the file size or convert the document to a ZIP file.

Once you’ve compressed the file size and it’s under 25MB, you can try attaching it to an email. If your Yahoo Mail can’t attach files, move on to other solutions.

Use a compatible browser

If you’re still wondering why you can’t attach files to Yahoo Mail, it could be because you’re using a browser that doesn’t work well with it. Yahoo has listed several browsers that are compatible with it and the best when accessing Yahoo Mail through a browser are Google Chrome, Mozilla Firefox, Microsoft Edge and Safari.

So, if you see a red Yahoo Mail exclamation mark on an attachment, it’s a sign that you can’t add an attachment. To work around this, switch to one of the browsers listed above and sign in to your Yahoo email account to send the email with the files.

Also, make sure you’re using the latest version of the compatible browser that you use to access your Yahoo email account.

Enable JavaScript in your browser

JavaScript is the computer language that powers the web. All the actions you can perform through Yahoo Mail are made possible by JavaScript.

There is an option in your browser to enable or disable it. So if you accidentally turn it off, you can’t attach files to Yahoo Mail.

By following your browser’s instructions to access the JavaScript option on it, you can enable it and then try adding attachments to your email.

Disable unnecessary/malicious extensions

Malicious extensions, downloaded to your browser from untrusted sources, can prevent you from attaching files to your Yahoo Mail. This could be due to the malware contained in them.

Furthermore, ad-blocking browser add-ons are also sometimes the cause of the “Yahoo Mail not allowing attachments” problem.

The only way to overcome this difficulty is to disable the extensions one by one and then try to add the files to the email to find the culprit. And when you find a fake extension, permanently remove it from your browser.

Clear your browser cache and cookies

Old and corrupted browsing data stored in your browser can also be the reason why your Yahoo Mail is not attaching files.

The problem seems complicated, but the solution is relatively simple. You just need to go to your browser settings and clear your browser’s cookies and cache along with your browser history.

This way you will load all the data stored in your browser including the corrupted ones and thus solve all browser related problems. After doing this, you can attach the file to your email.

Turn off your anti-virus program

Another reason why you may not be able to attach files to Yahoo Mail could be your anti-virus program. You read it right! Anti-virus programs may mark files as malicious, despite the fact that they are not, and prevent you from adding them to your email.

So, try disabling your anti-virus for a moment and then re-upload the files to your email. If that’s the case, then your anti-virus program is to blame. For the same thing to happen again in the future, you can either grant special permission to bypass verification or contact the program support for further assistance.

However, even after disabling your antivirus, if you still can’t attach files in Yahoo Mail, your antivirus isn’t causing the problem; turn it back on and move on to the next solution.

Server problems or Yahoo is down

Even if you can read, compose, or edit emails, Yahoo may have technical problems that prevent you from adding files. Yahoo Update may also temporarily disable some functionality. So if you can’t attach files to Yahoo Mail, it’s probably their fault.

To check if this is the case, what you can do is visit sites like or and check for Yahoo outages. You can also search all tweets from Yahoo to see if they’re temporarily down. And, if there’s a problem on their end, wait until the problem is resolved and then try adding an attachment to your email.

Fix your system error

It’s natural to have multiple tabs open while working. However, all open programs run in the background and consume system resources. This results in a processing load on the system and slows down the task being performed, such as adding attachments to an email.

In this case, what you can do is close all open programs and restart the system. This will help free up any busy system resources. Then try adding the attachment to your Yahoo Mail again.
