Hello, you can search directly in the folder "C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\Logs\MessageTracking". But, you will not have 90 days, unless you have a backup of the files.

By default, tracking logs are only kept for 30 days maximum, depending on the place used. You can use this command to change the MessageTrackingLogMaxAge to keep more days, and the MessageTrackingLogMaxDirectorySize&nbsp;to have more than 1 GB allocated. Set-TransportService [&lt;ServerIdentity&gt;] -MessageTrackingLogEnabled &lt;$true | $false&gt; -MessageTrackingLogMaxAge &lt;dd.hh:mm:ss&gt; -MessageTrackingLogMaxDirectorySize &lt;Size&gt; -MessageTrackingLogMaxFileSize &lt;Size&gt; -MessageTrackingLogPath &lt;LocalFilePath&gt; -MessageTrackingLogSubjectLoggingEnabled &lt;$true | $false&gt;
