I have found a few older posts referencing this topic (3+ years ago), but wanted to ask the larger audience.
I have a PVA bot that was created and published for use in MS Teams. We support some Teams channels that include our clients, which are external users that show up as guests. Everyone internally within my org can interact with the bot successfully, however it doesn't show up as available for the guest users. I've double checked all of the referenced materials from other forum entries (making sure External is enabled when publishing, making sure licenses are allocated correctly, etc.). I've even gone so far as to recreate everything in our demo environment (different domain than the rest of the company) and add myself as an external guest user, and have played around with all of the settings that made sense within the admin portals (PVA, Teams and Office 365), and still no luck.
Is it still a limitation of Teams and PVA that an external guest user of Teams can't interact with a PVA bot? Even when referencing via the @<botname> within the chat?
Appreciate any thoughts/feedback!
