Notes from the Field

I have been onsite working on remediating a partially completed Exchange 2007 to Exchange 2010 migration. This environment was then configured for Exchange Online Hybrid using ADFS 2.0 and Dirsync.

After reviewing the Autodiscover configuration, I discovered that something wasn’t right. In addition to this, I had received the following issues list from the customer.

Symptoms

1. Outlook for Office 365 mailboxes is not able to be configured using Autodiscover. This occurred on both domain and non-domain joined machines.
