I am the administrator and I cannot reset my own password. When I put my extension number in, it says it is not a valid mailbox #. Help!

SOURCE: NorStar T7316E Corded Phone Problem - mailbox locked

You will need to dial into the system admin of the voicemail
Feature 983
the password is dependant on how many digits your extensions use. 1020000 for 3 digit and 10020000 for 4 digit, 120000 for 2 digit.
go through the screens

Mailboxes, modify, scroll to password and press change.
Will reset to 0000.

SOURCE: had to rebuild mailboxes and now the main inbound number cannot dial internal extensions.

Does feature 983 still show as an inactive feature? You need to reinitialize the feature codes if the system was reset.

Please post what is currently happening.

SOURCE: Cannot Reset Password

feature 983 ... password 12000 or 1020000 generally. Hit mail box. enter mailbox #, reset password.

SOURCE: how to chg a norstar mailbox from 'General Delivery' to 'User'

check under the mailbox set up ( where you created it) for that extension that the extension number of that phone is on that mailbox> in other words, you could create mailbox 221, but assign it to 222. The Gen Delivery box is 100 which is the catch all for transfers that cannot be completed.
