You should receive an email almost immediately upon requesting a password reset. If you do not, it’s possible the email exchange server within your firm has set a delay on receiving that email to check that it’s safe, which typically creates a 15-minute delay.
Please do not attempt to reset your password a second time, as it will only replace the first request, making the first link you receive not work. If you did reset your password more than one time, please wait for the most recent link to arrive, as that will be the proper and workable link to reset your password.
