Microsoft apologized to customers of its hosted software services for businesses after at least three outages over the past few weeks.

"We aspire to deliver quality services, and in the last couple of weeks, we have fallen short of this aspiration," wrote Morgan Cole, who said he is responsible at Microsoft for making sure that Business Productivity Online Suite customers have a good experience. "I wanted to write here to apologize to you, our customers, for any inconvenience these issues may have caused." His blog post appeared at 10:30 p.m. U.S. Pacific Time on Wednesday.

He referred to three recent issues that customers may have had accessing the BPOS services, which include hosted e-mail, SharePoint and web conferencing. On Aug. 23, upgrades to network infrastructure caused "unforeseen problems that affected access to some services," he wrote. For about two hours, customers served from Microsoft's North America facilities may have had trouble accessing the services.
