To combat the spread of COVID-19, companies worldwide have switched to remote work in recent months. As a result, remote teams incorporate a wide range of communication technologies into their virtual workdays, such as Slack and Zoom and turn to concepts like the 7cs of communication. It’s feasible to integrate some of these platforms for increased functionality rather than using them independently. Synchronizing Slack with Outlook Calendar is a popular platform coupling.

When Outlook Calendar and Slack are linked, Slack will automatically update statuses to let others know when a team member is busy or unavailable throughout the day. In addition, at the start of each day, the app will deliver a notice with a brief synopsis of booked engagements. Also, the best slack apps for remote teams include Donut, Disco, Zapier, Polly, Lucid Spark, etc. The app will also provide links to Zoom, Skype, Webex, and other tools to help individuals prepare for meetings.
