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?

Accepted Answer

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

Then compare to the chart here:

Answer 2

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: )

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