We are about ready to start co-existence and migration from Exchange Server 2007 (Update Rollup 12) to Exchange Server 2013 SP1. I have set up a test mailbox on the new server. I am able to send email both internally and externally from that account, but I cannot receive mail in that account. I have been following closely the steps outlined on the Exchange Server Deployment Assistant as well as here - http://www.msexchange.org/articles-tutorials/exchange-server-2013/migration-deployment/planning-and-migrating-small-organization-exchange-2007-2013-part11.html
. The only special things to be aware of are:
- our 2007 server does not use SSL at all. We have added the name of this server, plus a legacy namespace to the SSL cert for the 2013 server. The cert has been exported from the 2013 server and added as an exchange certificate, but not yet enabled.
- we have not yet enabled Outlook Anywhere on the 2007 server.
- we using a new service name (mail) for the new server and discontinuing the name used on the old server, so that is not an issue to transfer
- We are using ORF as our spam filter. It is not going to be installed on the 2013 server until tomorrow.
We are hoping to complete all of the service-disrupting changes in the early morning hours in just a few days, following the steps outlined by Simon here: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_28350139.html
We are well aware that this is going to cause an issue with our Android and Windows Phone users, and they all understand upfront that their email will be disrupted on their phones until we can re-configure their devices (our MDM solution will allow us to edit iPhone ActiveSync settings, but not Android/WP).
Sorry for the long question, and I probably didn't give all the relevant information. I appreciate any help that you can give, or even to point me in the direction of how to troubleshoot this issue.
