Hi,
I am running Exchange 2013 in Coexist and Frankly hate it, nothing but problems I have been having. I haven't been able to migrate any mailboxes over to the 2013 environment because I cant get it working.
Here is my setup:
ExchangeFE1 - Exchange 2010 CAS
ExchangeMail - Exchange 2010 Mailbox Server
ExchangeUM - 2010 UM Role
Mail 13 - 2013 Mailbox, UM
MailExchange2 - SEcondary 2013 Mailbox Server
Exchangecas13 - 2013 CAS Server
Using OWA on the 2013 CAS server I can send/receive email perfectly fine both internal and external. I am unable to get Outlook to work at all. Even when I manually try typing in the server it doesn't work. What does work for no apparent reason is if I type exchangefe1 as the server and type the user on the 2013 mailbox and click checkname it then, fills in Mail13 as the server. However, if I manually type Mail13 it doesnt work. Even when I get done with that it wont let me open the mailbox says I have to already open it.
Alright so I Figure its a certificate issue. I add the local Exchange2013 cert to my PC's trusted root certificate, doesnt work. So then I create an SSL cert with Godaddy. It complains because the command name is company.domain.com.
The other issue is that Webmail Redirection doesnt work I looked at the logs it tries but never gets there. Right now I am running two seperate SSL certs one for production through Godaddy and 1 for our 2013 environment with Godaddy. There still might be a cert issue but this coexist is confusing me because I dont want to impact anything running.
I run autodiscover on the 2010 environment but its not configured on the 2013 environment. I can only have 1 SRV record so I dont want to take down the 2010 environment which is were all the mailboxes are.
Any assistance is greatly appreciated.
