I'm not sure how long this issue has been happening, but recently a few of the remote sales users were going to a sales meeting and wanted to set their Out of Office... however in Outlook 2010, they get this error message: "Your automatic reply settings cannot be displayed because the server is currently unavailable"

When I run the Exchange Remote Connectivity Analyzer, Autodiscover completes fine, but the next step fails:

Exception details:

Message: The request failed. The remote server returned an error: (403) Forbidden.

Type: Microsoft.Exchange.WebServices.Data.ServiceRequestException

Stack trace:

I've done some research, but I have yet to find a working fix for this... it seems like some permissions are messed up in IIS, but I haven't figured out what.

I swear, I've looked over everything a thousand times... NOW I notice that the External URL didn't have https:// on it, but http. In summary: Get-webservicesvirtualdirectory | fl identity,internalurl,externalurl Make sure the external URL IS VALID!! HTTPS, HTTP isn't acceptable! – Doughecka Jun 22 '12 at 12:34
