Microsoft warned users Monday that it will drop support for Office 2003 Service Pack 2 in three weeks, and it urged them to upgrade to a newer service pack that was involved in a dust-up earlier this year over blocked file formats.

The company's policy is to support an Office service pack for 12 months after it releases a successor. Microsoft rolled out Office 2003 SP3 in September 2007. It always extends that 12-month period to the following month's second Tuesday, the day it usually issues security updates.

"Any security updates released on or before October 14 will support both Service Packs 2 and 3," said a Microsoft employee identified only as "David" on a company blog. "Security updates released after October 14 will support only Service Pack 3."

Microsoft has patched 14 vulnerabilities in Office 2003 SP2 in the past two months alone.

Office 2003 SP3 also made news earlier this year when Microsoft apologized to rival Corel Corp. for blocking some of that software developer's file formats on the grounds that they represented security risks.
