US Report: Exchange beats Notes in groupware race

International Data Corp. yesterday confirmed that Microsoft's Exchange groupware outsold Lotus Development Corp.

International Data Corp. yesterday confirmed that Microsoft's Exchange groupware outsold Lotus Development Corp.'s Notes in the first half of this year.

The announcement comes in the wake of last month's report by the Washington-based newsletter Electronic Mail & Messaging Systems that Exchange outsold Notes in both the first and second quarters of 1998. According to IDC, Exchange sold 5.7 million seats in the first six months vs. 5.3 million seats for Notes.

The first two quarters notwithstanding, Notes remains ahead in the overall groupware race, with 21.9 million total installed seats vs. Exchange's 15 million, said IDC officials in the US. Trailing Exchange and Notes were Novell GroupWise with 12.4 million seats, Netscape's SuiteSpot at 5.2 million seats and SoftArc's FirstClass at 4.2 million seats, IDC officials said.

IDC's numbers did vary somewhat from EMMS'. According to EMMS publisher and editor Eric Arnum, Exchange sold 6.6 million seats in the first half of 1998 while Notes sold 5.8 million seats.
