The short version

  • Each has a real cost: Microsoft Teams resource-heavy application; slow to load and consumes significant CPU/memory compared to alternatives; Viber viber has limited relevance outside its strong regions, so building a communication strategy around it in North America or most of Western Europe reaches almost nobody.
  • They diverge on capability: Microsoft Teams covers Chat & channels, Viber covers End to end encryption.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Teams

  • Resource-heavy application; slow to load and consumes significant CPU/memory compared to alternatives
  • Limited channel structure; maximum of 200 public and 30 private channels per team
  • Cannot invite guest users to specific channels; guest access grants full team visibility
  • Unable to chat during screen sharing; limits real-time collaborative communication
  • Limited customization options for branding and interface; cluttered UX compared to Slack
  • Channels cannot be moved between teams; requires manual replication for reorganization

Viber

  • Viber has limited relevance outside its strong regions, so building a communication strategy around it in North America or most of Western Europe reaches almost nobody.
  • Ownership by Rakuten ties the app to a commerce and points ecosystem, and account data can be linked to Rakuten services in markets where that integration is active.
  • Business Messages pricing is metered per message, so a company sending high volumes of promotional content can find costs rise quickly compared with a flat fee model.
  • Viber has lost share even in some of its historically strong markets to Telegram and WhatsApp, so its regional dominance is not guaranteed to persist.
  • The desktop client depends on the phone app remaining active and connected, which is a limitation for anyone wanting a fully independent desktop messenger.
