Outlook not auto updating

As you can imagine there are many reasons which could prevent Microsoft Outlook connecting to Office 365, most commonly because the Outlook software version is not patched to the minimum required level, or firewall / proxy issues.However in this article, I specifically wanted to cover scenarios that comes up which are related to the autodiscover service, and how this may prevent Outlook connecting to Office 365 (Exchange Online) mailbox, or even resolving correctly in updating or creating an Outlook profile.You can manually check for updates from within any Office application.In order to switch from Windows Update to Microsoft Update, you can visit this Microsoft site which works for all versions of Windows.

This behavior can be seen when a PC is a member of an AD site, which doesn’t have a CAS server associated to it, and so many (in some cases all) internal CAS servers respond, and if you have more than 10 CAS servers, you can see this behavior.
