I am currently in the process of migrating from Exchange 2007 to Exchange 2013 SP1. &nbsp;I installed Exchange 2013 and got to the point where I added a new user to Active Directory and then gave it a new mailbox on the new server. &nbsp;I was able to send mail back and forth, as well as send and receive from the outside. &nbsp;After performing that series of tests, I moved my mailbox from the existing 2007 server to the new 2013 server.<br />
<br />
Once I did that my Outlook prompted me with a message stating a change was made by the Exchange Admin. Close Outlook and reopen. &nbsp;When I did that my Outlook will NOT launch at all.<br />
<br />
What am I missing?<br />
<br />
PLEASE HELP!

Exchange 2007 to 2013 Migration Issue

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
