I want to get contacts from outlook and receiving errors that I should add external user, but I use one which created app. Is it required to add a subscription and verify my credit card or I can add it for free without adding card?

Hi @yuliia-6663,
Thanks for the post! You can add Azure Authentication for free, but a credit card on file may be required in case you go over the cost limits. You won't be charged if you stay under the limits, though.

If you share a screenshot of your error message I can better assess why you are receiving that.
