SMASHDOCs is perfectly integrated into Microsoft Office365 and Teams

A separate registration is not required: Easy 1-click login via "SignIn with Microsoft".

Search a document in the connected SMASHDOCs app directly from MS Teams and add it as a tab in a channel with a single click

All team members can then immediately collaborate on the document

The role and rights of each team member can be defined individually for each document

Users who do not have an Office 365 account or access to the team where the document tab is located can easily be invited to a document by email
