During the period of self-isolation caused by the COVID-19 pandemic, our university began a remote class that utilized Microsoft Teams.　In this study, we employed the Teams User Report logs to analyze the actual conditions of use and clarify the usefulness of the software’s functions.　In addition, we examined the availability of ICT in university education after the COVID-19 pandemic.　At first, we examined the users’ device usage by analyzing the activity log that can be acquired in MS Teams.　Next, we examined the user activity counts for the spring semester, which involved an investigation of users’ Teams chat messages, private chat messages, calls, and meetings.　Further, the activity counts were aggregated every 7 days, and an approximate line was calculated through the least-square method by using a z-score.　Additionally, we examined the difference in activities performed each day of the week using the Kruskal-Wallis and Bonferroni method.　The results revealed that about half of the students had been attending remote classes using an iOS device.　When the iOS and Android numbers were compiled, it was found that about 60％ of the students had been attending classes using a mobile device.　Every activity displayed a downward trend during the second half of the examined period.　However, private chat messages displayed a different trend in comparison to the other activities.　The results clarified that the use of private chat messages was and will continue to remain useful for students once face-to-face classes begin.
