The following article provides some explanation of the content you may see in your Activity log report.
From the Activity page, use the radio buttons to filter between your tenant's Teams or all Groups. Apply a single filter, or multiple filters, to drill down into the activity. Export your Activity log report as a CSV file.
For a step-by-step guide, see Export activity.
The Activity log report will contain information from the Activity page based on the filters you applied. When you open the file, all columns will be visible, though the values may be blank depending on what was filtered.
Rename your report using a naming structure that will help you recall the information. For example, if you have filtered for owners who added sensitivity tags to teams during the date range January 1st to 31st, name the file Team_sensitivity_added_210101_210131.CSV.
