I can't receive any e-mail attachments
There are many reasons why your e-mail program may not be able to receive attachments. This page covers some of the more common reasons for attachments to not be received.
Not enough storage space
If the e-mail box is full of other e-mail messages and your storage space is limited to only a few megabytes, it's possible that the attachment being sent cannot be received. E-mail programs and e-mail service providers will automatically reject incoming e-mails if there is not enough space available to store the e-mails.
If you do not have enough storage, the person sending the e-mail should get an automatic response indicating that your mailbox is full or exceeded its allocated size.
Attachment is too big
Not all e-mail providers allow their users to send and receive e-mails with large attachments. If the file you want to send or receive is larger than 20 MB, we recommend using an online service to store the file in a location that you or your intended recipient can retrieve the file.
Attachment extension is not allowed
Because computer viruses and other malware spread easily through e-mail, restrictions are often placed on certain types of e-mail attachments. For example, Microsoft Outlook protects its users by automatically disabling the below file extension types from being received in an e-mail.
.ad, .adp, .crt, .ins, .mdb, .mde, .msc, .msp, .sct, .shb, .vb, .wsc, .wsf, .cpl, .shs, .vsd, .vst, .vss, .vsw, .asp, .bas, .bat, .chm, .cmd, .com, .exe, .hlp, .hta, .inf, .isp, .js, .jse, .lnk, .msi, .mst, .pcd, .pif, .reg, .scr, .url, .vbe, .vbs, .ws, and .wsh.
If the file being sent to you is one with any of the above extensions, the best method around this is to ask the sender to compress the file into a .zip or another compressed file format. They may also need to password protect the file to prevent the e-mail program from removing the file in the zip file.
If you are attempting to send a file that has any one of the above extensions, we suggest you do the same.
Attachment contains a virus
Make sure to scan the attachment you're attempting to receive or send for viruses. If the file is infected with a virus, trojan, or other malware, many e-mail servers will automatically reject it to prevent their users from becoming infected.
Problems with you installed antivirus
If you have an antivirus protection program installed on your computer, make sure it is not causing the problem by temporarily disabling your antivirus.
E-mail provider does not allow attachments
Some companies and e-mail providers will not allow e-mail with file attachments to be sent or received by their users as a security precaution. Today, most e-mail providers allow attachments in e-mails, but you may want to verify with your e-mail provider that attachments are allowed with their e-mail service.
Attachment is not being added or sent correctly
There is a possibility that the attachment is not being added properly to the e-mail.
Problems with Microsoft Outlook
If you are using Microsoft Outlook as your e-mail client, and you are having problems with attachments, see our attachments in Microsoft Outlook troubleshooting guide.
Problem with e-mail client or web service
The e-mail client software or e-mail web service may not be functioning properly, causing attachments not to be received.
If using an e-mail client on your computer, try closing the e-mail program and restarting your computer to see if that solves the problem. If the problem persists, it's possible the e-mail client has become corrupted and needs to be re-installed to correct the issue.
If using a web-based e-mail service, check with the service provider to see if there are any server issues that could be preventing attachments from being received. Sometimes, the service provider will post a note on the account homepage for each user, alerting them of system issues that could impact their ability to send or receive e-mail.
