The following sample demonstrates how you can query all the calendar appointments in a Mailbox and report on those appointments that have attachments, the number of attachments on each item, attachment Size and largest attachment details. Its uses the following AQS query to limit the result set EWS returns to only those appointments with attachments (this means the script will only run against Exchange 2010 or Exchange Online) $AQSString = "hasattachment:true" The script then does a batch GetItems to load all the details about attachments using the LoadPropertiesFromItems method. It then produces a report like the following To Run the script make sure you change the following variable to the mailbox you want to run against. $MailboxName = "user@domain.com" I've put a downloadable copy of this script here the script itself looks like. $MailboxName =  "user@domain.com"       $rptcollection = @()   ## Load...

The directory functionality in Exchange Web Services can be a little limited and so within Exchange 2010 without using LDAP to access Active Directory directly there is no direct way to access custom Resource properties on Meeting Rooms or where you want to access Custom Attributes. However using Custom MailTips is one way of working around this issue (although it means duplicating the information). For example to Create a Custom Mail Tip for a mailbox you use set-mailbox meetingRoom2 -MailTip "Expresso Machine" Then in EWS you can use this to retrieve the MailTip GetMailTipsType gmType =  new  GetMailTipsType();   gmType.MailTipsRequested =  new  MailTipTypes();   gmType.MailTipsRequested = MailTipTypes.CustomMailTip;   gmType.Recipients =  new  EmailAddressType[1];   EmailAddressType rcip1 =  new  EmailAddressType();   rcip1.EmailAddress...

The big thing is the past week or so has been the release of the Exchange 2013 preview and in the cloud world the Office365 (Exchange Online 2013) preview. One of the new things in the Auto-discover response if your using one of these is the EXHTTP node that gets returned eg I haven't quite found where this node is documented yet but if your creating Outlook Anywhere Profiles programmatically against the Office365 preview then the Server info from this node is important for building a Outlook Anywhere profile.  If your using your own POX based Auto-discover client you won't get access to this new information unless you set the UserAgent so the request looks likes its coming from Outlook. eg String snServerName = @ "https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml" ;   String OAProxy =  "" ;   String OAProxy1 =  "" ;   String ProxyCertName =  "" ;   ...
