For various reasons, the aforementioned Remove-HybridConfiguration cmdlet has been something that has been something I've had to review recently.
This cmdlet is not present in Exchange 2010, it is only available in newer versions of Exchange. For example if we try to find this cmdlet on an Exchange 2010 server, it is not present.
Only the Get, New, Set and Update-HybridConfiguration cmdlets are avai… Read the rest “Remove-HybridConfiguration Cmdlet”

When deploying AD FS and Web Application Proxy it is common to run into some networking issues. Normally this is due to firewall rules not being set correctly.
However we need to be aware of the default behaviour of WAP and factor that into our deployment.
When WAP is installed, it will write additional firewall rules into the Windows firewall. However, the default rules do not cover all monitorin… Read the rest “Unable To Access WAP AD FS Proxy Instance Externally”
This is one of those older documents, that for many reasons I seem to keep coming back to over the years. Even as we transition away from classic Outlook Anywhere to MAPI/HTTP, knowing some of the features/limitations of Outlook Anywhere and why MAPI/HTTP is a better replacement is something that will be around for a long time to come.
Since TechNet is dead, even though I know exactly what I'm loo… Read the rest “Exchange 2007 Outlook Anywhere White Paper”
The below are some of the older Office 365 welcome pages, thought it might be fun to make the screenshots available for reference. They are from an old blog post that never made its way out of the draft folder. So it was repurposed for this post.

Update 26-4-2021: RDCMan is now available again!
Rejoice and be thankful - see this post for more details please. I'll leave the post below for historical context.
A perennial favourite subject on the blog has been the topic of Remote Desktop Connection Manager (RDCMan). This was an internal Microsoft tool which was made available to customers. Initially version 2.2 then version 2.7 was released.
Managing and maintaining an Exchange server requires multiple actions. Not only do the Exchange CU and security updates need to be installed along with the Windows OS updates, it is also required to update and maintain the .NET Framework.
