Checking MPS and AD Integrity... Part #6: Mailbox and Public Folder Database
At the heart of HMC is MPS. And at the heart of this this MPS is that 2 mysterious databases, the PlanManager and ResourceManager databases. What I am trying to do is to attempt to provide you guys some script to help you to better know your environment to at least know the health of your environment a little bit as you are planning to move forward to Exchange Server 2010 SP1 Hosting Deployment.
I wrote the following script (as attached) a while ago to help myself to check if all the mailbox and public folder databases listed in MPS map to a mailbox and public folder database object in Active Directory. At the same time it also list down the GUID and the actual free and maximum space for those databases in MPS.
Here is a sample output for the powershell script from my test lab,
[PS] C:\MPStoAD> .\CheckMBPFServer.ps1

This is A very simple script that doesn't really do too much but more for information purpose. It will also export it into a TXT file where you can then open it in Excel and perform a text to column and split it using semicolon (;) and you will get something like this,
Enjoy!
