Why can I not send an email to 40 names in a contacts group

I can't send an email to group contact that contains 40 email addresses. I receive an error message saying that my mail box has reached it's maximum size limit at which you cannot send or receive any more content. Empty your deleted items folder from Outlook or delete messages from your mailbox to create more space. These boxes are empty because I have only just started using Outlook.
If you click on the "Details" box it shows - 

File: outlook\pstprx\storeas\utils\airsyncstatuscodes.h
Line: 104
HTTP/1.1 200 OK
MailStatus: 115
To re-try press F9...
Error Code: 0x80004005

Please can you help because I need to send mail like this regularly to a Contacts Group with a large number of recipients.
