Writing a Poweshell script to generate a gui interface for updating AD fields, which are replicated to Office365, using DirectorySync.
We have local AD accounts which have Office365 mailboxes, but no local Exchange mailboxes. When a user changes their email address, we allow them to keep the old and new address active for receiving email. Need to update proxyaddress
attribute with old email address for sync to Office365.
How can i use Powershell to update the proxyaddress attribute? Get/Set-Aduser and Get/Set-User do not have access to the proxyaddress attribute, and set-mailbox command does not work because there is no locally associated mailbox.
Suggestions?
