The company says it has found a bug into this particular feature
Users who want to change the email address they use to sign into their Microsoft email accounts are no longer allowed to do that, as the Redmond-based technology giant has temporarily disabled this option.According to a long Microsoft Answers thread, the company has recently found several issues with the feature and until a fix is released, renaming would no longer be possible.
Users who will attempt to change their login emails will be provided with an error saying that “the email address associated with your Microsoft account can’t be changed.”
A Microsoft support engineer has confirmed that the company is currently looking into the issue, but a fix won’t arrive sooner that Monday.
“Our engineering team has identified several issues with rename and has temporarily disabled the feature while they investigate.We are engaged on the issue and working to re-enable rename as soon as possible. We do not have a date yet, but will provide an update by Monday, January 7th. We appreciate your patience and apologise for any inconvenience," the forum moderator explained.
Users, on the other hand, are pretty outraged with the problem and call for Microsoft to release a fix as soon as possible.
“Very frustrating. Cannot even get into billing account for lost email address. I give up and will switch to another provider,” one of the users said. “I have a brand new computer one day old and because of this issue, I can't access apps, can't go into the store. I can't do anything until I can rename my account,” another one added.
Sadly, there’s no workaround for the problem, so users have no other option than to wait for an official fix. We’ve also contacted Microsoft for a word on this, so we’ll get back to you when we receive an answer.
