Exchange Setup – Certificate Is Expired – Part Deux

Posted on 19th November 2020 by Rhoderick Milne [MSFT]

Previously I managed to break one of my labs when replicating a customer situation and then had to fix it as noted in this post from 2017.

This time around though I really raised my game, and instead of one certificate being expired, all of them were. Yup every cert was toast. Trying to install the Exchange CU to update to the latest build did not go well at all. As you see below, all of the cer… Read the rest “Exchange Setup – Certificate Is Expired – Part Deux”

Low Exchange Disk Space Monitors

Posted on 16th November 2020 by Rhoderick Milne [MSFT]

Exchange 2013 introduced us to the concept of Managed Availability. This reduced the reliance on external entities such as System Center Operations Manager (SCOM) or other 3rd party monitoring tools. Exchange became self aware, started to monitor itself and even perform certain recovery actions.

As an administrator we can review output of some of these monitoring actions using Exchange Management… Read the rest “Low Exchange Disk Space Monitors”

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”

Exchange Setup Fails Due To Missing Scripting Agent Configuration File

Posted on 19th October 2020 by Rhoderick Milne [MSFT]

One of the key operational aspects to maintaining a sound environment is to document and understand how it is configured. This becomes more and more important with added complexity and also as time goes by. As the solution is in production for an increasing amount of time, the implementing staff may transition out of role or leave the organisation. They may have even been external consultants a… Read the rest “Exchange Setup Fails Due To Missing Scripting Agent Configuration File”

End of Exchange 2010 Support

Posted on 14th October 2020 by Rhoderick Milne [MSFT]

Exchange 2010 has proven to be a solid and innovative product over the last decade. From consolidating three different flavours of continuous replication, adding RPC Client Access and the Exchange Hybrid Configuration Wizard in Service Pack 2 we have a lot to be thankful for. However it is time so say goodbye to this old friend.

I can only imagine the number of time people have been running setup… Read the rest “End of Exchange 2010 Support”

Exchange 2016 CAS Namespace Cutover Authentication Failure

Posted on 10th October 2020 by Rhoderick Milne [MSFT]

You have prepped for months, and tonight is the night! It is the night of CAS namespace cutover to move the HTTPS namespaces from Exchange 2010 so that the point to Exchange 2013 or 2016. DNS TTL was decremented. Servers are all fully updated as are the Outlook clients and we are good to go.

The DNS change kicks in, and Outlook HTTPS traffic hits Exchange 2016 and we enter a spiral of never endi… Read the rest “Exchange 2016 CAS Namespace Cutover Authentication Failure”

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?”
