Audit log Deletion for administrators
We have Audit logs in Exchange admins settings. I tried to delete that logs but i could not. Support team says that due to security reasons that function have only developers team. And client cannot contact developers team. We are clients and we should have that ability . If official request should be made we are ready to make that request.
Office 365 does not allow for the deletion of Audit logs. In addition, audit entries are save for 90 days.
