Hello, I have read the thread http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/b9c895a8-ec11-45ca-a91a-34dc77582e88 but no reply from the person that originally asked the question as to know if the recommendation given has worked. Our scenario is: we have Exchange 2007 Mailbox, CAS, 2 HUB and UM. Before installing SP3 we were able to connect the EPA but after deploying the SP3 no success in connecting EPA. The only server to which we didn't install SP3 was the UM because the SP3 requires language packs to be uninstalled first. We followed the quoted documentation in the thread mentioned above but no success in connecting EPA to the Exchange's databases. Any further suggestions to troubleshoot this problem are welcome. MC. Today we've got a log that might give some idea on what is happenning: 20110421_081834: Find virtual directory Exadmin (Default Web Site) on server EXCHSRV01. 20110421_081843: Validating mailbox permissions for user account provided, please wait... 20110421_081843: Exception occurred while checking Exchange Information Store service on server EXCHSRV01. 20110421_081843: Error: System.InvalidOperationException: Cannot open MSExchangeIS service on computer EXCHSRV01. ---> System.ComponentModel.Win32Exception: Access is denied --- End of inner exception stack trace --- at System.ServiceProcess.ServiceController.GetServiceHandle(Int32 desiredAccess) at System.ServiceProcess.ServiceController.GenerateStatus() at System.ServiceProcess.ServiceController.get_Status() at Microsoft.Exchange.Epa.Server.CheckService() 20110421_082008: Warning: Profile Analyzer has detected that the configured user fails to collect data from at least a subset of the configured mailboxes in the following mailbox databases.

Marinho, Even when the log suggests a permissions issue, this can be due to a more general problem. If EPA cannot open MSExchangeIS service and you are sure you are using an account with the appropriate permissions, then make sure you have IIS 7.0 up and running on your Mailbox Server. Probably IIS was stopped on your mailbox server when SP3 was installed and the server was restarted. Go to Start > Administrative Tools > Internet Information Services (IIS) Manager. On the Connections Pane, click to select the server, then click Start on the Actions Pane, under Manage Server. Try EPA again. Hope this is useful. EC
