Microsoft Teams, a popular unified communications tool for businesses, does not have built-in texting features. However, third-party tools can be added to the platform to enable sending and receiving SMS and MMS messages. One such tool is Send-to, which integrates with Microsoft Teams and allows users to manage their contacts, reply to texts, and share messages across channels. To add Send-to or another messaging app to Microsoft Teams, follow these steps: pick a suitable texting app, set up Azure Active Directory, download and configure the messaging app, install the messaging app, and start texting from within Microsoft Teams.
