All things Exchange
The question of: I have just ran New-DatabaseAvailabilityGroup and I do not see a File Share Witness (FSW) folder or cluster resources. Where are all my Database Availability Group (DAG) and cluster resources…? What went wrong?
This is a common scenario when an admin is building a DAG, and during the process they check to see that what has changed on the servers. One thing that that causes a false … Read the rest “Dude, Where’s My File Share Witness”
Running scripts to start and stop services has been a task long associated with Exchange. For those who pre-date Exchange 2000, do you remember the fun issues with the increased WaitToKillServiceTimeout value? By default in ye olde days HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlWaitToKillServiceTimeout was 20,000 ms (20 secs). Installing Exchange increased that to 600,000 ms (10 minutes). … Read the rest “Script To Start Exchange Services”
In several recent engagements, there has been some interesting discussions about how to configure the CAS namespaces for the Exchange Web Services virtual directory. Specifically this was around the configuration of the InternalNLBBypassUrl in Exchange 2013 and 2016. Since this was set on Exchange 2007/2010 servers, there seems to be a desire to change it on 2013/2016 servers when troub… Read the rest “Busting The Exchange InternalNLBBypassURL Myth”

This is a quick tactical script to help Exchange administrators when resetting Exchange Monitoring mailboxes. Exchange 2013 introduced managed availability which is responsible for evaluating the health of Exchange 2013 and 2016 Exchange servers. Yes it does also probe downlevel servers, but let’s not get bogged down in that in this post. In order to do the synthetic user tests, mail and tests … Read the rest “Script To Automate Exchange Health Manager Service For Monitoring Mailbox Reset”
This is a tale of when a “quick” review of CAS namespaces quickly went off at a tangent. When working with the messaging administrator, let’s call him “Mike” to protect the innocent, he showed me the below for his Exchange 2013 server. He was quite happy with the config, but that bubble was about to be popped. Note that the ShowMailboxVirtualDirectories parameter has been added to allow us to se… Read the rest “Setting Backend Exchange 2013 / 2016 Virtual Directory”
Windows Server 2016 is available, and it is now supported to install Exchange 2016 onto this version of Windows. Initially this was not the case. Exchange 2016 CU3 added support to install Exchange 2016 onto Windows Server 2016. However, there was an issue with Windows which required based installations to be paused. The required fix has been released by the Windows team in KB3206632. This up… Read the rest “Exchange Support For Windows Server 2016”
In Exchange 2010, the Exchange Management Console allowed us to import certificates to multiple servers and to then assign the certificate to multiple servers simultaneously. In the Exchange 2013 and Exchange 2016 EAC, the option to enable the certificate for Exchange services is per server.
As you can seen in the Exchange 2016 example below, we need to select each server one by one from the drop … Read the rest “Assigning Exchange 2016 and 2013 Certificate To Multiple Servers At The Same Time”
