For example, business users opened documents 68 times more often than they participated in Yammer discussions.\n\n\nThe next most popular activity behind document access was adding SharePoint sites; seven percent of respondents said they add SharePoint. Just three percent of users conducted document searches, and less than two percent participated in Yammer discussions, viewed activity streams or looked up a colleague's SharePoint profile, according to harmon.ie.\n\n\n[Related Analysis: Google for Work vs. Microsoft Office 365: a comparison of cloud tools]\n\n\nThe research also suggests Monday and Tuesday are the most popular days of the week for opening SharePoint or Office 365 documents.
