Mail will not send Groups from my Contacts
I have a MacBook Pro, Retina 15inch. Mid 2014.Operating on Mavericks OSX10.95.
I have recently added a new Google email address to my list. I now have 4 email accounts which I access from my laptop Mail client account and these are connected to my iPhone 5c.
The iCloud account is connected to Mail.Contacts, Messages, Notes + 7 others, the Google account is connected to Mail, Contacts,Messages and Notes only.
My other two accounts, another Google account and a Virgin account, are connected to Mail only.
Now I find that I cannot select any Group in Contacts, when I select a Group and insert it into either BCC or CC many of the addresses are omitted and some are shown several times over in either box.
I have tried to create new Groups from All My Contacts but the same thing happens each time and I usually have to Force Quit in order to delete the faulty email
I have no problems with with one to one emails on any of my accounts .
I have never previously had this problem.
Stas.
MacBook Pro with Retina display, OS X Mavericks (10.9.5)
