Interpret the Email activity report

You can view your users' email activity by looking at the Activity and Users charts.

The Email activity report displays trends over the last 7, 30, 90, or 180 days. However, if you select a particular day in the report, the table shows data for up to 28 days from the current date (not the date the report was generated). The data in each report usually covers up to the last 24 to 48 hours.

The Activity chart helps you understand the trend of the amount of email activity going on in your organization. You can see the split of email send, email read, email received, meeting created, or meeting interacted activities. On the Activity chart, the Y axis is the count of activity of the type email sent, email received, email read, meeting created, and meeting interacted.

The User chart helps you understand the trend of the number of unique users who are generating the email activities. You can look at the trend of users performing email sending, email reading, email receiving, meeting creating, or meeting interacting activities. On the Users activity chart, the Y axis is the users performing activity of the type email sent, email received, email read, meeting created, or meeting interacted.

The X axis on both charts is the selected date range for this specific report.

You can filter the series you see on either chart by selecting an item in the legend.

The table shows a breakdown of the email activities at the per-user level. This data shows all users that have an Exchange product assigned to them and their email activities.

By default, user-specific information like usernames, display names, groups, and sites is hidden in usage reports. To learn how to display this information in usage reports, see Show user, group, or site details in usage reports.
