So after a fresh rest of the weekend, I attacked the issue this morning.

While the "directorylink" did not respond the way I expected, the DELETE REST API command still had the desired affect.



So I created a script that fixed 550+ users with the following:

curl -k --user ADMINUSER:ADMINPASSWORD -X DELETE https://SERVER:PORT/gwadmin-service/domains/DOMAIN/postoffices/POSTOFFICE/users/USERID/directorylink
