Hello I wanna see mail logs that sent 3 months ago by our user but I can't see any reporst except last month,is there any restriction about this in Tracking Log Explorer?thank you for now,

Hi Message tracing logs are retained for a certain period which you can see using this command: Get-TransportServer | select name,messagetrackinglogmaxage The default is 30 days which I think is what you have there. Steve Edit: if your hubs are separate from you mailbox server then use Get-MailboxServer to see the settings there.

Thank you very much Steve,

No worries. Cheers, Steve
