Exchange Server 2010 and Outlook 2007 - prompting for credentials
Posted on 2011-09-23
I know there are many articles on this and I have dilligently read through many of them, made various changes but am still getting this issue. Internal clients when launching Outlook 2007 are being prompted for user name and password. I understand this to be an autodiscover / certifcate issue. As far as I can tell autodiscover is correctly configured so I'm not sure whether it is simply because we only have a certficate for mail.ourdomain.com rather than an SSN one that also includes autodiscover.
So, here are my questions:
1. Am I flogging a dead horse until we get a SAN certficate that includes multiple names?
2. As these are internal clients, can I generate a self signed certificate to include the multiple names and install it on the client PCs? Will this break access to Exchange from outside?
3. Should running the following command return our CAS name or the external FQDN for the mail server?
Get-ClientAccessServer | FL identity,AutoDiscoverServiceInternalUri
Any help would be much appreciated!
