I can't receive any e-mail attachments

EmailThere are many different 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.

If this is occurring, you may want to consider using an alternate e-mail service such as Gmail that allows several gigabytes of storage space.

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 2MB, 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 within 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.

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 sent properly

There is a possibility that the attachment is not being added properly to the e-mail.

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 to not 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 home page for each user, alerting them of system issues that could impact their ability to send or receive e-mail.
