Hi All,

i am trying to audit one of the mailbox. my overseas staff are accessing one specific mailbox for more than 30 users, as per their requirement i had increased the owa concurrent access to 30 by creating a new throttling policy. they reported that few users are keep getting logout and unable to login successfully to the mailbox via owa.

if any possibility to check how many users were actually access to that mailbox via exchange shell, my exchange version is exchange 2010 S

A little bit research produce some good resources to see a list of all users who access Exchange via the Outlook Web Access (OWA) : http://windowsitpro.com/windows/q-how-can-i-see-list-all-users-who-access-exchange-outlook-web-access-owa

If you want to gather more depth information to find list of users who used OWA in Exchange environment, you can look into Lepide exchange reporter tool that provides a clear view of Outlook web access usage of individual user of each department into real time.

Hi Srini,

First thing first, Exchange 2010 SP1 isn't supported anymore so suggest you to upgrade to SP3 with latest UR.

You can take a look at the logon statistics filtering just OWA client like this...

Get-MailboxServer ServerNameHere | Get-LogonStatistics | ?{$_.applicationid -like "*Client=OWA*" -and $_.username -like "*UserNameHere*"}

Hi Srini,

Agree with Amit, you can use Get-LogonStatistics cmdlet to retrieves logon information.

More details refer to the following article :

View Logon Statistics 

The Get-LogonStatistics cmdlet retrieves logon information so you can view users or services currently connecting to your Microsoft Exchange Server 2010 servers. Logon statistics include information such as user name, logon time, last access time, and client version.

Best regards,
