I have Successfully installed the Exchange 2013 in environment that already have 2007 Exchange. Both Exchange Servers are on Domain Controller as we have less resources.

After Installation I saw in IIS "Default WebSite" with 80 and 443 Ports, and "Exchange Back End" Web with 81 & 444 Ports.

I migrated 2 test Mailboxes from 2007 to 2013 Successfully,

But When i open OWA with Default 443 port OWA Opens but the Mailbox not login successfully and through and
Exception type: Microsoft.Exchange.Clients.Owa2.Server.Core.OwaADObjectNotFoundException

When I Open OWA with Port 444, it logins Successfully.

All the Clients use Default Port 443 to access OWA and Other Exchange Services.

 How to Solve this Issue?

The OWA directory requires SSL. You need to open 443 and access OWA that way.

The other virtual dirs. should be using 443 as well.

Hi Genius,

Thank you for your question.

As you said that After Installation I saw in IIS "Default WebSite" with 80 and 443 Ports, and "Exchange Back End" Web with 81 & 444 Ports., it is default. You didnt worry about it.

Then I have answered you case with some notification by the following link:

When you access mailbox by URL, could you tell us what URL you are using? We could type Https://<Exchange2013CasServerName>.contoso.com/owa to check if we could login. We could also create a new account on Exchange 2013 to check if we could login. If the new account could login, we could run the following command on mailbox  on which we move mailbox:

Clean-MailboxDatabase <databasename>

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim

Thanks for Answer,

 Already Configured OWA requires SSL. When I use OWA with port 443 links works fine but Mailbox Don't login and through an Exception as i mentioned"  Microsoft.Exchange.Clients.Owa2.Server.Core.OwaADObjectNotFoundException"

I made mistake in my First Post, I updated the Question please check there also.
