Hello@@User17340439573038754577
Welcome to the LastPass Community. Because of the way your account is set up, please reach out to your LastPass admin and have them exclude you from the "Prohibit export" policy, that way you could export your vault data, (open vault, advanced options, export) after you export your vault data, they can add you to that policy again.
Please let us know if there is something else we can do for you.
Greetings!
