Enable mailbox auditing in Exchange Onlineīy default, Exchange Online does not have mailbox auditing enabled (and performing the steps above will not turn it on for you, either). Set-AdminAuditLogConfig -UnifiedAuditLogIngestionEnabled $trueīut guess what? There is still more to it than that. You will notice that the informational banner at the top of this page will change to say that auditing will be available within “a couple of hours.” Note that it is also possible to turn this on using PowerShell in Exchange Online: Enable-OrganizationCustomization Update: Microsoft says mailbox auditing will be enabled by default in all tenants by the end of 2018. If the link doesn’t exist, then your tenant most likely already has it enabled. Find your way to the Security & Compliance center, and browse to Search & Investigation > Audit log search. They are in the process of updating this to be on by default, but for now it is still necessary to turn it on yourself. However, one rather important piece to understand is that auditing (logging of certain activities) is not turned on by default. #Search-MailboxAuditLog -Identity andy -LogonTypes Owner -StartDate (Get-Date).Microsoft 365 has a powerful Security & Compliance center that is becoming cooler every quarter that goes by. #Search-MailboxAuditLog -ShowDetails -Identity “andy” -LogonTypes owner #Set-Mailbox -Identity “andy” -AuditOwner Create, SoftDelete, HardDelete, Update, Move, MoveToDeletedItems -AuditEnabled $true The exchange server version: is Exchange 2010 Version 14.3 (Build 123.4) I have enabled audit log for mailbox owner, but just can audit the owner access from OWA, and miss log for access from OUTLOOK client. ![]() Is there an issue in Exchange 2019 with Search Audit log ? or do you think this is a local issue in my configuration?

C:\>get-mailbox alan.reid | Set-Mailbox -AuditEnabled:$true To mitigate that risk I would recommend only enabling mailbox audit logging of mailbox owners for actions that involve deleting email.įirst, the mailbox must be enabled for mailbox audit logging before you can use the audit logs to prove anything. For admin/delegate situations this is usually a negligible amount, however mailbox owner actions occur much more frequently so they have a greater potential to consume a large amount of storage. However, auditing of mailbox owner actions is also possible, it is just not enabled by default.īefore we proceed I’ll just highlight that mailbox audit logging does consume storage on the Exchange server. ![]() In my demonstrations of mailbox audit logging I tend to focus on auditing administrator and delegate actions, which are a more common support scenario in my experience.
