Hi,

I need track when a user attempting to log in to another user's mailbox but cannot open.

Is there a solutions ?

Exchange 2010/2013

Mauro

I believe what you are looking for is the 'Non-Owner mailbox access report' which can by run from Compliance Management --> Auditing in the Exchange Admin Console.  Here is an explanation of that the report does:

https://technet.microsoft.com/en-US/library/ms.exch.eac.NonOwnerAccessLearnMore%28EXCHG.150%29.aspx?v=15.0.1076.0&l=0&f=255&MSPPError=-2147217396

You will need to turn on the auditing for each mailbox, otherwise the report is blank.  See this link for how to do that:

Now, this is only for Exchange 2013.  I don't believe Exchange 2010 had this level of auditing.  See here for an example for Exchange 2010:

• http://www.msexchange.org/articles-tutorials/exchange-server-2010/compliance-policies-archiving/auditing-mailbox-access.html
• http://exchangeserverpro.com/exchange-2010-mailbox-audit-logging/
• https://technet.microsoft.com/en-us/library/ff459237(v=exchg.141).aspx

Let me know if you need more information on these methods.

Thanks,

I know this solution to audit mailbox access but I need track when a user try to access another user's mailbox but login is denied.
