Microsoft has updated its handheld synchronisation software to address a glitch that prevented users mirroring data with a desktop. The problem affected users of devices running the Windows Mobile 5.0 operating system.
The company has released Activesync 4.1 to solve the problem, which saw users having trouble synchronising data via a USB connection when a firewall or parental controls were in use on the PC. Users synchronising data via a server or over a wireless network were not affected by the flaw. The patch is available from the Microsoft website.
Windows Mobile 5.0 is beginning to make inroads into the mobile device market after Microsoft launched its first mobile operating system five years ago.
The operating system is a rival to handheld and mobile/smartphone operating systems from companies such as Palm, Symbian and Research in Motion, maker of the Blackberry device.
Microsoft's Activesync software (also called Microsoft Exchange Server Activesync) is proprietary to Windows Mobile-based pocket PCs and smartphones, but was licensed by Nokia in February. This allows certain Nokia mobile devices to access Exchange Server 2003 data such as the calendar and contacts list.
In March, Symbian licensed Activesync for use in its Symbian OS and said it will develop an Exchange Server Activesync protocol plug-in for the Symbian OS messaging architecture, so its licensees can offer Exchange Server 2003 data synchronisation.
