This is a reminder for some or heads up for new tenants about an issue you might have run across that occurs when you try to change a user’s userPrincipalName in your local AD when using dirsync. If you change the UPN (left side of @) and keep the user in the same domain, dirsync […]

Exchange 2010 Federation (well, half-way there for now)

Federation is certainly a welcome and interesting feature in Exchange 2010. Being able to share calendar information with other organizations will greatly improve collaboration efforts, especially with shops leveraging both on-premise and Exchange Online services for their information workers.

Publishing Outlook Anywhere using NTLM Authentication on ISA 2006

The title of this blog sounds familiar, right? Maybe. Well, when I went searching for a way to do this I hit dead end after dead end. I searched everywhere (,, TechNet, blogs, forums, etc) and came up empty. It sounded like an obvious thing to want in order to minimize the impact on […]
