One of the most requested features for our Office 365 reporting application was for a report showing how many emails each user has sent and received over a given period.
This information has a number of applications:
- You can see if users are receiving a high number of emails, which could indicate that the organisation's spam filters are not working effectively.
- You can check if users are close to reaching their mailbox storage limits.
- You can see when there is an increased amount of mail traffic over any given period.
Follow this guide and use the PowerShell script included to get this data.
