My problem is that I'm doing a migration from Linux mailserver "Postfix" to Exchange using a Microsoft tool called "Microsoft transporter suite" this tool requires that all users to have their passwords entered in "CSV" file in order to access their mailboxes through IMAP protocol and migrate them to Exchange.
Talking to the Customer i'm doing the migration for, he said users can't share their passwords and we can't reset their passwords too because we'll have to send them all the same password to their e-mails before resetting it since Postfix authenticate to AD.
I'm trying to find away to reset their passwords in order to do the migration but when they are prompted reset their passwords on their PCs they don't have to type the old password!
Is this ever possible on AD? If not is there script that would generate passwords on AD and send it to the user's mail before resetting it?
I have 850 users and there's no way I can tell each one to personally come and enter their password...
Im out of options.
