The reason I asked Noel was this:
In Outlook Express, groups did not import nor export so I created my "groups" this way.
In a new message window, enter all the recipients it the To, CC or BCC field. (Your choice). Put your own address in the To field if using CC or BCC. An alias "group" address could be created. Eg: In the Contacts list, create a new address using your address
with a display name of your choice such as "My Group".
Put "My Group" in the To field and all the recipients in the CC or BCC field. X out without sending. Then click the Menu Button at the top left and Save As File and save it to the desktop. You can also drag it to the Taskbar if you wish.
Now when you want to send a message to this "group", just click on the icon that was created when you saved it and a new message window will open with the recipients already inserted. WLMail does not even have to be open.
If you have any text that you always use in the body of the message, that can be created when you make the template. Subject as well if you wish.
Since this has been an issue since WLMail 2012 was introduced, for me it would be a good workaround until it is fixed. After two years, I wouldn't hold my breath for a fix though.
