***** If your running Exchange 2010 please see http://gsexdev.blogspot.com/2010/03/mailbox-size-gui-exchange-2010-remote.html ******** Okay time for a new version of the mailbox size gui the last version had a number of large bugs and the quota code looked like it had been written by a drunk squirrel. So this version firstly fixes the bugs in the quota code and the bugs with Deleted items sizes and adds some new functionality. The first addition is a drop down box that allows selection of which quota value you want to report on Eg exchange offers 3 quota levels Warning, Prohibit Send and Prohibit Send and Receive so the script will now allow reporting on which ever Quota usage you want to look at. This section still needs a little work to get better performance as it re-queries the server for mailbox sizes when you change the quota dropdown box instead of just reusing the current result. The second and most exciting feature is the mailbox size growth feature this is the biggest ch...

I survived my hiking adventures and am back on deck to those people who sent me an email over the past couple of weeks sorry there are just too many and not enough time to answer then and the mark all read button kind of works really well so if it was important ping me again. Cheers Glen

Im off from a couple of weeks holidays should be back around the end of may. I've enabled comment moderation to stop the spammers while im away. May all your coding and scripting be happy :) Cheers Glen

The following is a script that demonstrates how to create a contact using a SOAP string and a simple web request. While this is not a very elegant solution as long as you have your SSL certs sorted out it should work okay. I was planning something a little cooler but time is really short at moment but this is still okay though. When creating a contact there are a few properties that you should set to get a fully working contact object. So the first part of the script is divided into required props which if you are using this in a pipeline you should always make sure you set. If you don’t you may find things like your contacts don’t appear properly when you try to use the contact in the Outlook Address book. The rest of the properties are optional which you can set if you have the information. This is not a complete list of contact properties that can be set within EWS just the majority of the most common ones for a full list please refer to the Exchange SDK. The big advantage if you...

This is a handy little sample to have in your bag of tricks when you need to exchange messages between disparate messaging systems. This code sample is relatively straight forward in that it uses a file stream to read the byte stream of the EML file which is already in MIME format and then uses a createitem operation and posts the MIME content from the data stream to the Exchange Message Store. The only trick that comes in is when you create the Item in whatever folder you want you need to set the message flags property PR_Message_Flags so the message will appear as a normal Sent Mail in Outlook (otherwise it will just appear as a draft). Also you need to set the flag value so it will also appear as Read (unless you want to have it as unread.) The sample itself uploads an eml file from the c: drive to a users sent items folder I’ve put a download copy of the code here the code itself looks like [warning this code sample may cause global warming if you don't configure your pc t...

*** There is an update version that include mailbox acls here http://gsexdev.blogspot.com/2008/10/exchange-reverse-permission-audit.html Exchange mailbox permissions getting you down, don’t know who has access to who’s mailbox, rouge admins or legacy permissions or configurations keeping you up at night, can’t get any more the 500 horses out of the V8 under the bonnet. Okay seriously this is kind of rollup script of a lot of vbs scripts that I’ve posted over the past couple of years in regards to Exchange Mailbox, Send and Receive As, Store and delegated Admin rights. It enumerates permissions from Active Directory firstly from all Mailbox rights, Send and Receive As Rights for Exchange Users and then all Mailbox Store ACL’s and finally from the Root Exchange container in the configuration partition to work out the Rights that have been delegated for Exchange System Manager Delegation wizard. It adds all the permissions to ADO.NET datatables and does some calculations to work out fir...

I’ve been working on some permissions scripts in the past couple of weeks and thought I’d post a powershell port of some VBS code from this http://msdn2.microsoft.com/en-us/library/ms992469(EXCHG.65).aspx msdn article. I’ve use this code before in a variety of scripts to read permissions from the Exchange Mailbox DACL via the msexchmailboxsecuritydescriptor AD property. Of course one should never try to set mailbox rights using this property as per http://support.microsoft.com/kb/310866/ so make sure you always treat it as read only. So what I’ve done is put together a quick sample that uses the new ActiveDirectorySecurity class in .NET 2.0 to basically load the DACL from the bytearray representation of the DACL that’s stored in this property. Also I’ve included some code to retrieve the Send-AS and Receive-AS rights from the AD object's DACL. The code only looks at the Implicitly set ACE's and not the Inherited ACE’s (this could be easily changed) it queries ever mail...
