allan: So does this imply that if VM has not been used in 60 days, then after that no message can be left by a caller, or are they just not hearing a greeting, but can still leave a message?
If the mailbox is deleted due to inactivity, and someone then tries to leave a message, a new mailbox is automatically created and the caller hears the default greeting of 'You have reached the mailbox of <phone number>...'
