How to add an external user to a list ?

[Githendra23]

Hi everyone,

I am looking for assistance with Sharepoint Sites.

Essentially, I'm attempting to trigger an power automate flow by putting an external user's email address in a list. Unfortunatly I'm not able to do so, I have gone to the settings > sharepoint > active sites > [My site] > external sharing and changed to invite existant or new users, but it still doesn't work.

What do I have to do to enable this ?

I apologize for sending screenshots in another language.

Thank you,

@Githendra23 : Hi, Could you please confirm if this guest user added to guest users in Microsoft 365 admin center ?

Hi @Surya_Pammi,

Thanks for the reply,

I can confirm that this guest user in the screenshot is indeed in the Microsoft 365 admin center just for an example. But, I would like to add a guest user's email address without them being in the admin center just to clarify.
