Only the Get, New, Set and Update-HybridConfiguration cmdlets are avai… Read the rest “Remove-HybridConfiguration Cmdlet”

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. This is not a new requirement, and has been a required task for many years now. With that being said, there is now a tighter requirement and is enforced by Ex… Read the rest “Expediting NET Framework Install For Exchange”
CAS Namespace planning is frequently an issue with Exchange deployments. Why? For the simple reason that it is either totally skipped or glossed over.
Any Exchange design worth its salt must have careful attention applied to the CAS role. While it is possible to drop in the HUB role, and it works well in the default configuration this is not also true for CAS. Unless your org… Read the rest “Exchange CAS Namespace Planning”
The Managed Availability (MA) feature provides a very capable automated monitoring and management framework. Managed Availability allows Exchange to self diagnose and to self correct issues without having to escalate to a human. The requirement for this feature was born out of necessity for Exchange Online. MA was one of the things released with Exchange 2013 but not every Exchange admin was im… Read the rest “Managed Availability Resources”
Exchange 2013 CU23 has been released to the Microsoft download centre! Exchange 2013 has a different servicing strategy than Exchange 2007/2010 and utilises Cumulative Updates (CUs) rather than the Rollup Updates (RU/UR) which were used previously.

When looking at the details of objects in Exchange Management Shell, it is often useful to know when an object was created or modified. In a recent Office 365 engagement, the customer was convinced that one of the other administrators had made an unauthorised change to their environment as there was an apparent recent change to the Exchange Hybrid Object.
The details of the this object can be view… Read the rest “Incorrect or Misleading Exchange Attribute Date”
Many enterprises are moving forward with their digital transformation plans, and as part of this and server updates Domain Controllers are being updated to newer versions. The Windows Server 2008 and Windows Server 2008 R2 end of support in January 2020 is also a business driver.
DC upgrades can happen independently of the Exchange team. In many cases the Exchange admins are not notified of the p… Read the rest “Exchange Not Using New Domain Controller”
One of the edge features in Exchange is the Cmdlet Extension Agent. You can find some documentation online for this component along with some previous blog posts on this site.
What can sometimes take people by surprise is that Exchange setup checks to see if the Cmdlet Extension Agent is enabled during setup. If it is enabled and the necessary configuration XML file is not present on the server b… Read the rest “Cmdlet Extension Agent Blocks New Exchange Server Install”
