I have a model driven power app. There is one lookup field which select username from AAD table. In main form, this is perfectly working for regular users. Regular users are able to search names and select usernames. However, this is not working for guest users. It is showing 0x80040265 Business Process Error.
I have all regular+guest users in one outlook group. And security role is provided to that group. In short, both: regular and guest users have same security roles. Then why regular users are able to search names and guest users are getting error?
