Please check those contacts that refuse to go into the Mailing List group. If there is not a vaild email address for the contact then they will not move because as a Mailing List (used to send one email to a group) they must have a valid email address.

All the recalcitrant contacts have valid email addresses - for 2 of them they share the same email address as their spouses, although they are, obviously, different people! Thank you for the advice.

an email address is a single entity.. A husband and wife that share an email address are a single entity. So you will be unable to drag an entry for the same email address into the list as one that is already in the list. Even if you have artificially attempted to create two entries for the same address in the address book with different contact details.

Many thanks Matt - this answers the question!

Matt is correct, but there is a Workaround:

As an example: in your address book you have two people with same email address. Bob Smith has email address: thesmiths @ domain Jan Smith has emails address: thesmiths @ domain.

These two people are perfectly ok in an address book, but to get them into a Mailing List will not work by conventional method. So do the following to get them into the Mailing List.

In the Address Book Select one of the people and edit the email address. In the example I put a letter A in the front. Jan Smith has emails address: Athesmiths @ domain.

Now move both people to the Mailing List. As the email addresses are not the same they will both move to Mailing List. Once in Mailing List, select the Mailing List double click on Jan Smith to edit the email address by removing the 'A'. click on OK

Now you should have two people sharing same email address in the Mailing List and ifyou go back and check the address Book entries you will find them correct.

Many thanks Toad Hall. This has worked perfectly.
