Exchange Online is a key part of Microsoft’s (NASDAQ: MSFT) Business Productivity Online Suite (BPOS) of services, providing email in the cloud for millions of subscribers.
Last week, Microsoft scrambled multiple times to end glitches in the service that plagued many users with lack of email deliveries for as many as nine or more hours all told.
“On Tuesday [May 10] and today we experienced three separate service issues that impacted customers served from our Americas data center. All of these issues have been resolved and the service is now running smoothly,” Dave Thompson, corporate vice-president of Microsoft Online Services, said in a post that was part apology and part early post mortem on May 12 to the Microsoft Online Services Team Blog.
