We have a small office of less than 15 employees. We are looking to migrate our on-premises Outlook Exchange to a cloud based Exchange. We are running various versions of Office including XP and 7. Our email is Exchange 2003, 2007 and 2010. I understand this causes some issues on its own and may require some type of upgrading. Suggestions? We are also looking at migrating one email at a time. Is this possible? Will we still be able to share calendars, etc.? Any other suggestions/comments you have would be appreciated.
Thank you.
