Hi Yajvendra,

We have approx 5000 licenses in our tenant.

Will it impact anything if we enable this feature?

Thank you,

    Hi Ganesh,

    This feature is available to tenants with over 10,000 non-trial Exchange Online licenses. Attempting to enable it without meeting this requirement will result in an error message.

    Thanks.

      Hi Yajvendra,

      Thank you for your quick response.

      Then we need to wait for this feature to be supported for fewer than 10,000 licenses, right?

      I hope Microsoft has some plan.

      Thank you,

        Currently, the feature is enabled for larger tenants only. In the event of unintended or accidental delicensing for smaller tenants, if the administrator re-applies the license, recovery is generally faster (mostly within 24-hour provisioning delay duration).
