Exchange HCW Detects “Wrong” Version

Posted on 2nd November 2020 by Rhoderick Milne [MSFT]

When running Exchange setup or the Exchange Hybrid Configuration Wizard (HCW), I always recommend looking at the version information that is shown on screen. This is part of the gross error check to make sure that the correct version is being used.

This habit is one of the recommendations made in the Mistakes to Avoid Installing Exchange CU post.

Sometime you still may see something that surprises yo… Read the rest “Exchange HCW Detects “Wrong” Version”

QuickTip – Which Managed Availability Components Are Unhealthy?

Posted on 28th September 2020 by Rhoderick Milne [MSFT]

Exchange 2013 introduced the Managed Availability feature, so Exchange can self monitor and perform recovery actions upon itself. While this has greatly helped Exchange become more self-healing, one of the downsides is that there is no real UI for Managed Availability. The only UI is the Managed Availability Event Logs. All of the configuration inside of Exchange is done using PowerShell. The … Read the rest “QuickTip – Which Managed Availability Components Are Unhealthy?”

Beware the Exchange Hybrid Configuration Wizard Doppelganger

Posted on 27th July 2020 by Rhoderick Milne [MSFT]

Perhaps the best thing to come to Exchange over the last 10 years was the Hybrid Configuration Wizard (HCW). While many take this feature for granted, if you had to manually deploy Exchange 2010 SP1 hybrid to Exchange Online you will shudder at the mention of the Service domain. But let’s not dredge up those memories…

Recently an update was released to the HCW, and initially the update looke… Read the rest “Beware the Exchange Hybrid Configuration Wizard Doppelganger”

Remove-HybridConfiguration Cmdlet

Posted on 15th July 2020 by Rhoderick Milne [MSFT]

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”

Expediting NET Framework Install For Exchange

Posted on 6th April 2020 by Rhoderick Milne [MSFT]

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”

Exchange CAS Namespace Planning

Posted on 2nd April 2020 by Rhoderick Milne [MSFT]

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”
