The fact that this functionality has been pulled from the GUI in Exchange 2007 doesn't appear to have been a very popular decision amongst sysadmins i guess the majority of which don't want to look at a line of code or script. While this blog/post isn't probably for those people If you are really ruing the loss of Mailbox size information out of the GUI don't think about what you have lost but whats been gained through the flexibility of Powershell and the Exchange Cmdlets. GUI's are great for displaying simple information but anyone who's been working in IT for any length of time knows that requests are rarely simple and not always logical when dealing with management.

It’s one thing you do need to dedicate some time too to get your logic right. I posted a calendar permissions helper for powershell a couple of months back I thought this would be a pretty simple task but when I started to test the library it ended up taking a numbers of hours to get the logic right. To summarize the things to watch out for when setting permission via EWS two important points are. The first is that the ACE’s for the EWS security roles enumerations and Outlook roles don’t match. There are only sutle differences but if you need these roles to marry up in Outlook you need to include your own routines to do this. When you want to modify...
