Greetings, I am running Exchange 2013 in a coexistence environment with Exchnage 2010, and was troubleshooting Outlook prompting for password when starting Outlook to create a new profile. When looking in the event log on the 2013 CAS server I noticed the following events. These events occured when no changes were even made by myself to the system: EventID: 3025: The configuration of the Outlook Anywhere virtual directories has been updated. EventID: 3005: The configuration of the Outlook Anywhere virtual directories has been updated. EventID 1001: [RpcHttp] Application starting. EventID 1002: [RpcHttp] Application shutting down. No idea what is making these changes and/or if they are coming from my existing 2010 CAS servers or what is going on. Any thoughts is appreciated. Cheers

Hello, Have you configured outlook successfully? Please run get-autodiscovervirtualdirectory | fl to check your autodiscover settings. Cara Chen TechNet Community Support

Greetings Cara, Thank you for the response. After running the command the following details are provided...Since I do have multiple 2010 CAS servers I will just focus on the 2013 CAS server where my mailbox is located: Name: Autodiscover (Exchange Back End) Internal Auth: ntlm, WindowsIntegrated, WSSecurity) External Auth: ntlm, WindowsIntegrated, WSSecurity) Basic Auth: False Digest Auth: False Windows Auth: True Identity: CAS2013\Autodiscover (Exchange Back End) Cheers
