Office 365 Outlook Users Hit With Log-In Problems

Users of Office 365 services experienced connection problems late Friday afternoon, with outages seemingly concentrated in the western U.S. states.

Update 3/27: The problems were reported by users as resolving at around 6:00 p.m. on Friday, with Microsoft issuing portal statements around 8:30 p.m. that "email services are now operational." Microsoft's Twitter page had little information, but referred to "MO97271" for more information.

Problems regarding Office 365 use spiked after 2:00 p.m. Pacific Time, according to crowdsourcing data put together by the Web site, which tracks user complaints. A heat map produced by DownDetector showed that the complaints were most concentrated in the Southern California region, San Francisco and Seattle.

Data polled by DownDetector indicated that users complained about log-in problems (34 percent), server connection problems (34 percent) and Outlook problems (30 percent). The problems started today at 5:41 p.m. Eastern Daylight Time, according to the site. It appears to be an unresolved log-in problem that is continuing into early Friday evening.

Microsoft seems to be signaling that it'll send its next progress report on Saturday, March 25 at 1:30 a.m. UTC, according to a comment posted at DownDetector.

Microsoft provides a service health dashboard for organizations managing Office 365 services, which will show service outage information. However, Microsoft's only public resource page for Office 365 indicated that "everything is up and running" at around 5:00 p.m. PT. The public portal was not indicating any service problems.
