Out of interest, in EAC, where is a message trace report searching, is that just searching through the tracking logs, or is it looking at other logs as well? I am guessing it is a different set of logs, as tracking logs go back 30 days, whereas trace seems to return up to 90 days of history.

Is there any specific exchange role that could be assigned to our investigation team so they can run searches of tracking logs and message traces for investigations. We dont want to give them anything elevated where they could make changes, but so they can do such searches themselves without having to take up the time of the support teams. <br />
<br />
I presume searching logs and running message traces cannot impact performance if run during peak working hours?<br />
<br />
we have quite a complex exchange environment, half is exchange online 2013, and the other is older exchange 2010 on prem

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
