Export Contacts from a Mailbox Contacts Folder or Public Folder to a CSV file using EWS and REST

As I had a few questions about exporting contacts to CSV from both Mailbox and Public folders I've added some new functions to the my EWS contacts module to make this easier.  I've added to new cmdlets the first is Export-ContactsFolderToCSV This will export a contacts folder to CSV's either the default Contacts Folder in a Mailbox or a secondary Contacts folder if you enter in the FolderPath eg to export the Default contacts Folder use Export-ContactsFolderToCSV - MailboxName user@domain.com -FileName c:\exports\contacts.csv To export a Secondary Contacts Folder use Export-ContactsFolderToCSV - MailboxName user@domain.com -FileName c:\exports\contacts.csv -Folder \Contacts\SecondContactsFolder Export-PublicFolderContactsFolderToCSV This will export a Public Contacts Folder to a CSV file to use this use Export-PublicFolderContactsFolderToCSV -MailboxName mailbox@domain.com -FileName c:\exports\PublicFolderexport.csv -PublicFolderPath \folder\folder2\contact
