The MS email program is great, but we had to stop using. Not having any contacts in the program hindered us too much.
Suggestions-
One is to have something similar to Outlook when the user manually adds an email address, save that somewhere so it can be used for future emails.

Another option is to make any email address on the personnel table available on any emails in MoversSuite.
Or something to that affect. Some kind of address book people can use within MS.
