How to find out Microsoft Outlook Web access version?

Question

I need to find out the version of particular installation ( this one ) of Microsoft Outlook Web Access only with normal user privileges.

I also know that the server has the following services:

PORT    STATE SERVICE
25/tcp  open  smtp
80/tcp  open  http
443/tcp open  https
993/tcp open  imaps
995/tcp open  pop3s

It is possible? If so, how?

You can get Microsoft's internal version number from the OWA web UI's About page.

Then compare to the chart here:

If you telnet into the SMTP Port (25) you will get the following server banner:

Version: 6.0.3790.4675 this equals to exchange 2000 (version number list here: http://support.microsoft.com/kb/158530/en-us)

/edit: correcting myself: The version does not point to a native exchange - it could very well be a Small Business Server 2000
