HI @Anonymous ,
Could you please share a bit more about your scenario?
Do you want to list all related contacts for current sign in account in same company?
Based on the needs that you mentioned, I think the Office365Outlook.ContactGetItemsV2(...) function could achieve your needs. I have made a test on my side, please consider take a try with the following workaround:


Firstly, add a Office 365 Outlook connection in your app.
Add a Dropdown control in your app, set the Items property to following:
Office365Outlook.ContactGetTablesV2().value
Add a Data Table control in your app, set the Items property to following:
Office365Outlook.ContactGetItemsV2(Dropdown1.Selected.id).value
then all related contacts for current sign in user would be listed within above Data Table.
When the end user run your app, it would ask him to provide his own credential to create a connection to the Office 365 Outlook connector, so the Office365Outlook.ContactGetItemsV2(...) function would always return all related contacts for current sign in user.
Best regards,
