Guest accounts cannot choose approvers in document approval flow

[Corey_l]

I am creating a flow acts on a selected document in SharePoint.  The Approver list is a variable and when a Guest account tries to choose an approver the selection box does not resolve the name and the email address is not added and the flow fails due to a null value in the email address.

The connections I am using are as follows:

SharePoint: provided by run only user

Office 365 Users:  provided by run only user

Approvals:  provided by run only user

Microsoft Teams:  Uses my connection

Office 365 Outlook:  Uses my connection

When all are set orun only user this is what they see

When it is set as above this is what happens when they run the flow:

Is there any way that allows Guest Users to enter and resolve email addresses or aliases?

Hi Corey

Unfortunately you could only run Approval flows to people only in your Organization currently.

You can check this idea:
