October 30, 2013, 5:47 PM — Maintenance work on Outlook.com's calendar application is now in its second week, and the lengthy, ongoing tune-up could be causing problems for users.
The maintenance began on Oct. 23, according to a note posted on Microsoft's Live Status dashboard, where people can check on the status of the company's consumer online services.
"You might see error messages when creating/editing birthdays. The checkbox to get notifications in the Options page may also be disabled during this time," the announcement says.
Asked for an update, a Microsoft spokesman confirmed on Wednesday that the work hasn't been finished. "We apologize for any inconvenience and expect the updates to be completed soon," he wrote via email.
It's not clear in what ways Outlook.com's calendar is being improved.
Outlook.com is Microsoft's new webmail service. It made its debut in mid-2012 and has since replaced Hotmail.
Microsoft describes Outlook.com as a total reinvention of webmail, from the user interface to the back-end platform. It's supposed to give Microsoft a stronger competitor to Google's Gmail and Yahoo Mail.
It malfunctioned in August in various ways for several days and experienced a prolonged outage in March.
