SCRIPT: Show OWA Users

This is a modified script that shows current OWA/HTTP logons to the Store(s) on a given server(s). The script takes NetBIOS names of servers as command-line arguments (separated by spaces), uses the Exchange_Logon WMI class to connect to a server and retrieve list of users currently logged on.

Usage:

ShowHTTPLogons.vbs EXCH1 EXCH2 EXCH3

If Cscript is not your default scripting engine, it is advisable to add Cscript before the script name when you run this:

cscript SHOWHTTPLogons.vbs EXCH1 EXCH2 EXCH3

The script ignores non-HTTP logons, and displays the mailbox (display name), logged on user, and the Store name in a comma-separated format.

To dump output to a CSV file, simply add >MyOutputFileName.csv to the end of the command when running it, as shown here:

Cscript ShowHTTPLogons.vbs EXCH1 EXCH2 EXCH3 >MyOutputFileName.csv

The script does not display logons by the System account (NT AUTHORITY\SYSTEM), but these are counted and displayed as a summary, in addition to the number of actual HTTP logons by users. Please note, a single OWA session can have multiple HTTP logons on the Store, so this is by no means a way to calculate the actual number of users currently logged on using OWA. You will see repeated entries for mailboxes because of this (... it's not a very tidy script, but written in a hurry.... hopefully I will be able to fix that at a later date).

Note: You will need to extract the file and rename it with a VBS extension.
