Microsoft Back Office 3.5I or for that matter my department started using Microsoft Exchange Server way back in 1997/98. We started with Microsoft Exchange Server 5.5 which is part of the Microsoft BackOffice Server 4.0.
BO includes Windows NT Server 4.0, Internet Information Server 4.0, Index Server 2.0, Certificate Server, Transaction Server 2.0, Message Queue Server, Internet Connection Services for Remote Access Service, FrontPage 98, Exchange Server 5.5, Proxy Server 2.0, SNA Server 4.0, SQL Server 6.5, Site Server 3.0, Systems Management Server 1.2

It was the greatest opportunity for me to be involved in a full scale IT Master Plan. I started working in 2nd September 1993 in Computer Department and posted here in 1st March 1995.

We have been using the same version ever since although there is already Microsoft Exchange Server 2007 in the market as I’m writing this entry…
