Find email address in Public Folders

Looking after several thousand mailboxes, public folders and distribution groups can sometimes make it difficult for you to keep track on where certain email aliases are assigned.

Now mailboxes, distribution groups and mail contacts are easy as you can add a filter in the Exchange Management Console to find these, however the same cannot be applied for Public folders.

Once again PowerShell comes to the rescue in the form of the Exchange Management Shell. Running the following command will bring up all the details you need:

Get-MailPublicFolder email@address.com | Get-PublicFolder

output from Get-MailPublicFolder

This command will bring up the name of the public folder along with the parent path so you know exactly where the public folder lives by showing the folder name and the parent path so you can navigate to the folder in question.

Not only do you get to find the public folder you get to learn a little more about Power Shell with the nice "Tip of the day" that appear in the Exchange Management Shell

Now that deserves a beer!

WinSXS taking up space after Service Pack install

I was working on a users desktop the other day who had an SSD installed a while back (back when 128GB were silly prices!) and it could only hold 64GB and it was full (well around 500kb free). This meant her .ost for Outlook couldn’t expand, causing no end of problems for her. Cleaning out temp files and rebuilding the .ost managed to bring back around 2GB which just wasn’t enough really so after hunting around on the drive to find where the rest of the space had gone I found the WinSXS folder. Now this folder was changed from XP to Vista quite a bit from the old .INF files being in there in XP to .mui, .exe’s in Vista and beyond. This folder allows you to run application such as SFC (System File Checker) or when installing additional features and roles in Server 2008 etc. As handy as this is, it can take up a great deal of space, especially when Service Packs are installed (which was the case for this poor user). To help clean this folder up there is a handy tool built into Windows, which can be run from the command prompt (you need to run the command prompt in Elevated Mode to run. To do this, hold down shift and right click on the command prompt icon and select Run as administrator…) which does a nice job of doing it all for you. Please bear in mind after this runs, you won’t be able to roll-back from the Service Packs. The command to run is below:


DISM /online /Cleanup-Image /SpSuperseded
This will take around 20-30minutes to run (depending on the OS and how much space it can reclaim) and can usually bring back around 3-5GB, which is the perfect amount of time to crack open a can of beer
