Posted on by Rhoderick Milne [MSFT]

On the Retrieving Packets Received Discarded Perfmon Counter From Multiple Servers post, Tim commented that he had found the script very useful when troubleshooting discarded packets on Exchange 2013 DAG servers.  Using PowerShell  it is very easy to extend the search to discover which other servers are impacted by the packets received discarded issue.

PowerShell – CannotConvertArgumentNoMessage

This is an interesting tale from a customer who was trying to get a list of Outlook clients that were connecting to their Exchange 2010 servers.  They wanted to validate the Outlook versions that were connecting, due to Exchange 2013 requirements and also that Outlook 2010 must have SP2 installed at this time.

A quick search of the interwebs turned up a script, and they though all was golden at tha… Read the rest “PowerShell – CannotConvertArgumentNoMessage Where Object Error”

Posted on by Rhoderick Milne [MSFT]

Abraham Lincoln made the famous quote that it is impossible to verify the accuracy of information on the Internet.  Well, OK he didn't but it was a semi-funny intro on the subject  of quotes…..

  • Single quotes  -->     ‘
  • Double quotes –>      &ldq

Posted on by Rhoderick Milne [MSFT]

Exchange Online in Office 365 has a very similar RBAC implementation to the on-premises installations of Exchange.  After previously bumping to an issue with Exchange Online (EXO), and then twice again in the last fortnight this bubbled to the top of the publishing pile.

In this environment, a custom Management Role was created called Level1-HelpDesk.  This is a copy from the Mail Recipients built-… Read the rest “Remove Multiple Management Role Entries In Office 365”

Using Exchange PowerShell Remoting With Integrated Scripting Environment–ISE

Posted on by Rhoderick Milne [MSFT]

One item that is very prevalent is people directly loading the Exchange PowerShell snapin into the Integrated Scripting Environment (ISE).  This is not supported from the Exchange point of view, as Exchange requires that Remote PowerShell  be used with Exchange 2010 and 2013.

Let’s look at how this should be done.

PowerShell Profile For Integrated Scripting Environment

In this post we will look at some of the mechanics behind creating a profile file which will customise the start-up behaviour of the Integrated Scripting Environment (ISE).  This will also serve as a precursor to additional posts on tweaking ISE for Exchange purposes.  The catalyst for writing this was twofold.  Firstly, an administrator was having issues trying to get ISE to process a profile scr… Read the rest “Creating PowerShell Profile For Integrated Scripting Environment – ISE”

PowerShell Script To Get Exchange 2010 Active CAS Connections

Posted on by Rhoderick Milne [MSFT]

Purpose of this script is to report on  particular performance monitor counters for Outlook RPC Client Access, OWA and Exchange ActiveSync on multiple servers.  This was required as during the course of the year there have been a few issues where the third party load balancer device was not really doing equitable load balancing.  In some cases 60% of the user load of 50,000 mailboxes was directed … Read the rest “PowerShell Script To Get Exchange 2010 Active CAS Connections”

Posted on by Rhoderick Milne [MSFT]

In Exchange 2010 the Set-AdServerSettings  cmdlet is used to manage the AD environment in the current Exchange Management Shell (EMS) session.  In Exchange 2007 there was a variable called AdminSessionADSettings  for the same purpose.  Exchange admins normally use the Set-AdServerSettings cmdlet to change a session’s view scope, so that they can see objects in multip… Read the rest “Set AdminSessionADSettings ViewEntireForest To True By Default”

PowerShell Input Output Escapades

Posted on by Rhoderick Milne [MSFT]

After using various types, architectures and generations of computers over the years there is always the habit of “you go to what you know!”  In other words once you figure out a solution to an issue, you then use that repeatedly in the future as you know the process/steps involved.  This adroitly describes me when it comes to doing certain command line tasks.  If I were being a bit… Read the rest “PowerShell Input Output Escapades”

Quick post for a Friday!

A customer had an “interesting” issue where the DAG networks were not being displayed inside the Exchange Management Console.  The underlying reason is because the implemented firewalls between Exchange servers, and then restricted network traffic between Exchange and the DCs.  This is not a supported situation.  For details on the firewall restricting traffic aspect please… Read the rest “How To Rename DAG Network Using PowerShell”
