Global change to voicemail greeting

[grd]

Is there a way to change the default voicemail greeting for everyone? We've been asked to apply a temporary message for the Christmas/New Year break for every mailbox (personal and group). Also, can it be reverted back to what it was previously at the end of the period?

Quite frankly... No.. In fact, I can't think of any system at all that you could do this. Granted I don't know them all, but I have been in this business for 30 years so... Yeah.
