I am looking for a way to export all the mailboxes and do some chnages to the caller input section. We are doing some dial plan changes that require that to be changed. I am talking about 3000 mailboxes so looking for a good way to do it. Any ideas?
The way I would do this would be export all users out using Bulk administration tool to a CSV, modify the 0 out extensions and import the relevant data back in and use the Update button in Bulk administration tool. I know this works in version 8 and above but not quite sure about 7 and I dont have a version 7 server handy.
