Microsoft now at 400 million active Outlook.com accounts

Microsoft has completed moving its Hotmail.com users over to Outlook.com and officials are now claiming the company has 400 million active Outlook.com accounts as a result.

Microsoft officials announced the completion of the Hotmail-Outlook.com transition on May 2. Microsoft officials added that they've migrated 150 petabyes of email over the past six weeks.

As part of the announcement, officials also said they are adding two new features to Outlook.com: SMTP Send, making it easier to send mail from different email addresses; and deeper SkyDrive integration.

The new SMTP Send supuport streamlines the process of sending from an alias, without recipients seeing a message saying “Sent on behalf of…”  And on the SkyDrive front, users can now insert files and pictures directly from SkyDrive.

In February of this year, Microsoft officials said they had 60 million active Outlook.com accounts. At that time, officials said they'd be closing Hotmail and moving the hundreds of millions of existing Hotmail.com users to Outlook.com. 

Of the current 400 million, 125 million Outlook.com users are accessing their accounts from mobile devices, officials said.

To those Hotmail users who are struggling with the Outlook.com interface: I'd suggest you check out this video and frequently asked questions (FAQ) document. I've heard from many (many, many) of you that you can't find your calendar, contacts, etc. Hopefully this page will provide some help.
