#
#  Manages contacts in two domains based on mail-enabled users in the other domain.
#	- Contacts are created for new users.
#	- Contacts are deleted if the source user no longer meets the filter requirements.
#	- Contacts are updated with changed information.
#
#  NOTES:
#   - Requires RSAT roles and features installed. Ref http://blogs.technet.com/heyscriptingguy/archive/2010/01/25/hey-scripting-guy-january-25-2010.aspx
#	- Attribute deletions are not replicated - only attribute adds and changes.
#   - A user account is needed in each domain with permission to create contacts.
#	- The passwords for these user accounts must be stored in secure files using the command:
#		read-host -assecurestring | convertfrom-securestring | out-file C:\scripts\filename.txt
#

## The following filter is used by Get-ADObject to decide which users will have contacts.
$strSelectUsers = 'ObjectClass -eq "user" -and homeMDB -like "*" -and -not userAccountControl -bor 2 -and -not msExchHideFromAddressLists -eq $true -and -not displayName -eq "Administrator"'
