Do I need to download Microsoft Teams to use it?
To maximize utilization of Microsoft Teams it is still best to use the desktop application. But you are not limited to just the desktop app.
On the go
Most of us always have our phone or tablet with us. We are more likely to refer to our mobile devices for quick peaks at assignments, announcements, or chat messages than open our computer. To answer this demand Microsoft has provided a mobile version of the app for both android and iOS. Many find this mobile app useful with video calls conducted via Microsoft Teams.
By default, the landing page of the mobile app is the chat feature but you can easily navigate to the other features with the navigation links at the bottom.
For both students and faculty, hard disk space and RAM are often challenging to work around with every app we install and projects and papers to save. With all the apps we already have installed we are sometimes faced with the decision of uninstalling one app in favor of another. Office 365 solved that problem by providing a browser-based version of all their apps, which includes Microsoft Teams.
It has all the functionality of the downloaded version except for offline access. If you are already using the desktop or mobile version, everything you do there will also appear here so long as you were online when you did them as Microsoft syncs its content with your account on office.com.
