Digital Strategy: Fostering Collaboration Across the Globe

Hello everyone,
we are currently drafting our digital strategy and of course digital collaboration plays a huge role in this. Our organization is spread over 13 different locations with offices in Europe as well as Sub-Sahara Africa. Now I am wondering which approaches, tools etc. you pursue/use in order to foster collaboration between all employees. Right now we are exploring different functions within Microsoft Teams because this is the main communication tool we use. Since we are a global disability organization all tools/platforms need to be accessible. But besides collaboration, what do you use in order to foster non-work-related interaction in the virtual space? Do you use any tools to get an overview of the vibe among employees? I would be super interested in exchanging with you and learn about different and innovative approaches.
Many thanks and all the best
