Microsoft announced that OWA supports Viva Topics, meaning that users with Topics licenses can add topic cards to messages, and those who receive the messages will see topic cards if they also have licenses. Support is coming soon for topi cards in Teams chat. Being able to use topic cards in mainline applications increases the attractiveness of Viva Topics a lot. Whether it’s enough to convince more Microsoft 365 tenants to plunge into knowledge management with Viva Topics remains to be seen.
