Problems Sending Large Email Messages or Attachments
Time to Complete (in minutes): 15
- I am having problems sending large email messages or attachments. What is wrong and how can I fix it?
Note: The VT Google Apps Mail servers will only allow email messages of less than 25 MB in size. If you receive a message from the server stating that your file exceeds the allowable limit each time you try to send a large email message or attachment, then your message is larger than 25 MB.
When you send a message, the total message size is determined by:
To eliminate the problem, reduce the size of the message you are sending, perhaps by breaking it into several messages. If you have to send a large file attachment, you can try the following solutions:
- The amount of text in the message
- The size of any file attachments
- The amount of header information added by the SMTP server
- The size of the encoding information for each attachment
- If the file you are sending is a graphic and does not need to be high resolution, save it as a JPEG or GIF file at a lower image quality to reduce the file size to about 24.5 MB. In general, use the JPEG format for photographic images and graphics with lots of color depth. Use the GIF format for images or line art with large areas of single, flat colors.
- Split large files into smaller files. Use WinZip for Windows or StuffIt Expander for Mac OS to compress the files. You can then mail each split and compressed file separately.
- There is no pre-set email size limit if you are sending an email message internally to Exchange (from your Virginia Tech Exchange account to another Virginia Tech user on the same Exchange system). However, the email size is effectively limited by the available free space for your Exchange account. Likewise, the receiver also has an allocated amount of free space on the Exchange server.
- There is a 25 MB size limit on messages sent to and from your Virginia Tech Exchange account and any non-Virginia Tech Exchange address. This includes messages sent to the VT Google Apps Mail servers. Once again, this could be further limited by the amount of free space for your Exchange account.
- To check the amount of free space you have on your Exchange account if you use Outlook 2003/2007/2010 as your email client, refer to Viewing Mailbox Size of Exchange Account with Outlook 2003/2007/2010 (http://answers.vt.edu/kb/entry/2236/).
