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?

I have resolved the Issue by Running these Commands on all exchange servers.

Get-ClientAccessServer ExchangeServerName | Add-AdPermission -AccessRights ExtendedRight -ExtendedRights "ms-exch-epi-token-serialization" -User "Domain\Exchange Servers"

Get-MailboxServer ExchangeServerName | Add-AdPermission -AccessRights ExtendedRight -ExtendedRights "ms-exch-epi-token-serialization" -User "Domain\Exchange Servers"
