Unity Changing AD user without deleting mailbox

[tryingtodomyjob]

For Unity, is there way to associate a mailbox from one AD user to another AD user without deleting the mailbox?

Do you mean moving the mail box from one user to another user ?

Toggle the mailbox to not be LDAP-synced, change the mailbox username/alias to the other username, toggle it back to LDAP synced, and run a DirSync. Change the mailbox extension if the new user isn’t also taking over the old user’s DN in CUCM. Reset the PIN, probably. And of course this whole process assumes that it’s permissible for the new user to access/hear the old user’s messages, recorded name, greetings.
