Booking App Office 365 Account Teams Chat attachment issue

SGH 1,226 Reputation points

Microsoft Booking App Calendar Office 365 account uses Teams for chat. In the Teams chat, the attachments are uploading and sending to internal users, however for external users it is not working.

The Booking App is used by the doctors and they want to share files to the patients.

By default, Microsoft Teams uses one drive for sharing the attachments. Is it possible to share to external users for this booking account only or do we have to enable tenant level ?

Is there any other security related issues ?
