Hello,
Maybe there is a solution, I have a Flow that gets triggers by PowerApps. This flow runs perfectly if I'm or the second person clicks the button. I added one more person to the app who has full access to the shared email box. if this newly added person tries to run the flow it fails. But it still working for me.
Any suggestions?
Thanks,
Omi
Make sure that anyone who is trying to run this flow has access to the shared mailbox this is what the error message suggests and may be it takes a while for the permissions to be applied on the shared mailbox.
