Microsoft Teams

Microsoft Teams has become a necessary tool for agencies that work closely with enterprise clients. Many large corporations have standardized on Microsoft 365, and when a client lives in Teams, the agency often needs to meet them there. Guest access makes this workable — agencies can join client Teams environments for project communication without maintaining their own Teams infrastructure, or they can host clients in their own tenant.

Where Teams shines for agencies is in its bundled value. If you're already paying for Microsoft 365 for Outlook, Word, and Excel, Teams comes included at no additional cost. The deep integration with SharePoint for file storage and Power Automate for workflows means agencies can build quite sophisticated collaboration setups. Meeting recordings with automatic transcription are particularly useful for client presentations and workshop documentation.

Compared to Slack, Teams is generally considered less polished for day-to-day messaging but stronger for scheduled meetings and document collaboration. Most agencies that use Teams do so because their clients require it, rather than choosing it as their primary internal tool. The pragmatic approach for many agencies is running Slack internally while maintaining Teams presence for client-facing communication.
