Mitel 3300 admin voicemail passcode pin lost

Source

What do you do when the the passcode to mailbox 9999 has been lost/changed?

If you have a backup or can FTP to the controller you can find the codes unencryped in folder

3300_icp\vmail\temp\db\backup\vmail\0000PARM.BIN

Just open in notepad.

Dont know what versions this works on but i have used it on MCD4.0
