I have an a regular problem of being unable to forward e-mail messages to my group contacts using Windows Live Mail 2012 , Windows 8.1 and Internet Explorer.

I have 6 groups of contacts with each group varying from 6 to 14 people. The message I get is "message could not be sent". The interesting thing is that if I enter the e-mail addresses of all the group one at a time into the "To" box  the message will forward without problem.

I would appreciate any help or suggestions.
