former email subscriptions now gets the error EmailSubscriptionExternalUsersNotAllowed

Hi,powerbi_desa 

Regarding the issue you raised, my solution is as follows:

1.First, check for licensing issues: when the license expires and you continue to use the free license, it can cause the subscription to fail. Even if you now have a new license, your subscription may still be affected by the last misstep. Make sure that all users involved have the appropriate Power BI Pro or Premium Per User (PPU) licenses.

2.Second, based on your error, the subscription can't be delivered to external users because the workspace requires a premium license. Make sure that the external user has the necessary licenses, or consider giving the necessary licenses to the external user.

3.Then, check to see if you reach your subscription limit: there might be a limit to the number of subscriptions per report or dashboard. Check that you've reached the maximum limit and try to reduce the number of subscriptions

4.Finally, check that the subscription feature is disabled: Your organization may have disabled the subscription feature for external users.
