EWS Contact Vcard Export script

A couple of months ago I posted a Vcard export script for exporting the Global Address list from Exchange 2013/ExchangeOnline using EWS's findPeople operation. To round this script out I thought I'd post another script that allows you to export from a Mailbox's Contacts Folder using EWS's built in ability to export the Contact's MimeData as a Vcard as explained in http://msdn.microsoft.com/en-us/library/office/dn672317(v=exchg.150).aspx .

This script is pretty simple it just 

• Binds to the contacts folder of the Target mailbox
• Enumerates the contacts in the contacts folders
• Gets the MimeContent of each of the contacts and saves that as a vcard

To run this script just pass the primarySMTPAddress of the mailbox you want it to run against and the directory to export to eg

./exportVcardEWS.ps1 mailbox@domain.com c:\vcardexports

I've put a download of this script here the code looks like

1. ## Get the Mailbox to Access from the 1st commandline argument  
2.   
3. $MailboxName = $args[0]
