Hi Popowich, Thank you for your reply.
It will support only one domain that is hosted off site. I dont really care what mail server I use. Features: secure, calendar, contacts, search.
I currently have less than 20 clients, not looking like we will get more in the future. They currently use microsoft outlook, I want to move away from microsoft as much as possible, so eliminating outlook is preferable. I have 2 clients without any email, that I can use for testing.
Thank you
Maurice
