Why choose Microsoft Teams or Lark?
In terms of communication and collaboration features, both competitors offer chat, file sharing, mentions, groups/channels, GIFs/emojis, threads, 1-1 video calls, and screen sharing. Microsoft Teams also offers breakout rooms and recording while Lark has a higher limit for group video calls (up to 500). Both competitors have AI capabilities, user profiles, and storage, but Microsoft Teams has a newsfeed and "do not disturb" mode while Lark has meeting transcription and dedicated CSMs. Both competitors offer mobile, web, and desktop apps, integrations/API, SAML/SSO authentication, end-to-end encryption, and two-factor authentication.
