With the availability of Orange's latest smartphone, the Windows Mobile 5.0-based SPV M5000, Microsoft's mobile OS is set to be widely deployed within business. Analysts have predicted the new smartphone, with its Blackberry-style push e-mail, will also fuel demand for Exchange.
Companies wanting push e-mail will have to rely on Blackberry until Microsoft releases an update to Exchange 2003.
Ovum analyst Tony Cripps said enterprise adoption of the new smartphone was likely.
The SPV M5000 is the second smartphone to use Windows Mobile 5.0. O2 launched an XDA smartphone based on the new operating system last month.
Gartner vice-president Nick Jones said, "Microsoft sees Windows Mobile as a way of driving Exchange upgrades."
According to Gartner, the number of smartphones in Western Europe and the USA will rise to 28% of all mobiles in 2008. Jones said, "If these things start penetrating the corporation, push e-mail becomes almost a necessity."
Microsoft plans to launch its Windows Mobile Direct Push Technology upgrade in Q1 2006.
