How to communicate in one way

Internally:

Only communicate using MS Teams. Please do not use Outlook, Whatsapp, or Gmail to communicate with your colleagues. A lot of messages tend to get lost because not everyone is using MS Teams for communication and as a result there is massive confusion. Please stick to MS Teams and change your status according to your availability

Externally:

For external partners, clients, or consultants that are not a part of MS Teams, please only communicate via Outlook
