Hello.
A client has migrated to Exchange 2010 from Exchange under Windows NT Server, and then jumped to Exchange 2010.
For the most part, all is functional. After a bit of a struggle to get autodiscovery working, with SRV records, Free/Busy data, etc., Out of Office ceased to function. The Out of Office began to malfunction after server-side changes were made to correct the Autodiscover features needed for Free/Busy, OWA, etc.
Initially, new Outlook profiles were created under the original Windows accounts and the popup 'Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later.'
We've opted to try a new Windows profile and recreate the Outlook profile. Initially, right after creating the Outlook profile (using Outlook 2007 connecting to Exchange 2010 Stadnard), clicking on Out of Office Assistant, Outlook hesitates, and was in a limbo of retrieving information from the server. After about 2-3 minutes, it failed with the popup message.
Testing the autoconfiguration settings via Ctrl+Shift+Click on the Exchange icon on the dock, everything looks perfect, all Successful and no issue at all.
I've had some good folks on this forum assist us with Autodiscover and split DNS fixes (using a local domain of .local and an outside domain of .com for SSL certificate popups), so we're wondering if this is causing some issues as well.
We are using Exchange 2010 Standard SP1 on Windows Server 2008 R2. Also, during the default intervals at 1am or 5am, the OAB does not automatically download to the clients, causing them to have a stale/old OAB and in turn, causing Free/Busy to not display info when creating resources in the calendars.
Is Autoconfigure misconfigured that is causing all of these issues?
Please advise.
Thank you.
NSI, IT.
