Hello,
I've recently introduced an Exchange Server 2013 in a single Exchange 2007 Server environment.
While most things seem to work out of the box, I have some issues:
When I use the Get-CalendarProcessing cmdlet on a mailbox hosted on the Exchange 2007 server or go inExchange admin center > recipients > resources, I get this error message:Microsoft.Exchange.Data.Storage.ConnectionFailedTransientException: Cannot open mailbox /o=<org>/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=<server>/cn=Microsoft System Attendant. ---> Microsoft.Mapi.MapiExceptionNetworkError: MapiExceptionNetworkError: Unable to make connection to the server. (hr=0x80040115, ec=-2147221227)
Another problem is that, when I navigate toOutlook Web App > People and try to search the directory, I get this:An error occured while searching. Please try again.
Same problem there:New mail > To: > Search Contacts and Directory: Can't connect. Please try again later.
And last but not least: I can’t connect Outlook to the Exchange 2013 server, unless I add the "DS Server" entry in [HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider]
Any help would be highly appreciated!
