How much time do you spend trying to determine what happened in your on-premises and cloud-based Exchange environments?

The free edition of Netwrix Auditor for Exchange delivers visibility into what’s happening in your Exchange environment — both on-premises and in the cloud. This free Exchange reporting tool monitors changes to your mailboxes, role groups, mailbox databases, and Exchange Server and Exchange Online configurations. It also keeps you updated on all successful non-owner mailbox access events. Daily email reports detail every one of these actions within the last 24 hours.

See what changed
Indicates which objects and settings were added, modified or removed, with the current and past values for all modifications.
Monitor non-owner mailbox access
Reports on successful non-owner access to specified mailboxes. You can see what mailbox was accessed, when and from which workstation the access occurred, and which items the user viewed, edited or deleted.
Automate auditing
Collects and consolidates data about user activity from multiple sources and automatically reports on it by email on a daily basis.
Increase efficiency
Eliminates the need to analyze mountains of native logs and activity in Office 365 Admin Center by providing consolidated information about every action in a human-readable format.
Save your IT budget
Relieves you from extra expenses and painful budget approvals, and will never expire or stop working when you need it.

Without regular monitoring of what’s going on in your Exchange environment, you can’t be sure that user activity is in line with established processes and controls. Reviewing native logs for this information is anything but efficient — and now you have an alternative. This freeware for Exchange Server and Exchange Online delivers accurate and meaningful data about every change and non-owner mailbox access event automatically, eliminating the major blind zones of Exchange.

Any inappropriate change to your Exchange Server or Exchange Online could cause system downtime that interrupts your business. And any non-owner mailbox access event could lead to sensitive corporate data being stolen. Our free reporting tool enables IT admins to review this critical activity across their on-premises, cloud or hybrid Exchange environment so they can identify and remediate inappropriate or malicious actions before they cause serious damage.
