AOL Email Limitations

E-mail File Attachments Size Limit

The largest piece of e-mail that you can send or accept from the Internet is 16 megabytes (MB). This includes the message text, headers and the attachment combined.

If the file you are trying to transfer exceeds 16 MB, you will need to either compress the file or split it into smaller parts.

If you attach multiple files, they will be zipped (compressed) into a single file by the AOL® software before they are sent out.

The recipient of your e-mail will need to unzip the files after downloading them. If the recipient is signed on to the AOL® or CompuServe® service, the files will be unzipped automatically after sign-off or upon download.

If the recipient of your mail uses a different Internet Service Provider, they may need special software to unzip or decompress the files before viewing or using them.

To find and download third-party software for compressing files, please go to AOL® Keyword: AOL Download Center, then search for ZIP. You'll find a selection of different programs you can download and can follow instructions for using these programs in the documentation that accompanies them.

Of course, if you are having problems with the AOL software then is a good place to send large files.


Email Recipients Limit

The maximum recipients that can be included per messages is 100. Although this has been known to be nearer 16. There is also a limit on the number of email recipients per connection.
