Moving 300 million users from one popular (and often free) email system to another is bound to ruffle feathers. And feathers were ruffled.

It has been a bit of a rocky road, but Microsoft now says it has successfully migrated a whopping 300 million active Hotmail users to its newer Outlook.com email service and now claims 400 million users of that service. According to a blog post announcing the milestone on Thursday:

“Today, we’re excited to announce that we’ve completed upgrading all Hotmail customers to Outlook.com. Coupled with the growing organic excitement for Outlook.com, this has pushed us to over 400 million active Outlook.com accounts, including 125 million that are accessing email, calendar and contacts on a mobile device using Exchange ActiveSync.”

And, the transition required the migration of 150 petabytes of data over in six weeks, no small feat. Given the comments on our earlier story about the transition (or “forced migration” as some put it), there are more than a few disgruntled Hotmail users out there, an issue Outlook Group Product Manager Dick Craddock addressed in the blog:

“Of course, whenever a widely-used consumer service makes any substantial change, there will always be some folks that don’t like it, and that shows up in the feedback, too. It’s gratifying in a sense because it means those customers loved the previous set of changes we made. With a communication service that is constantly evolving, we try to strike the right balance between bringing out major improvements and keeping true to what our customers love.”

Microsoft also more tightly integrated Outlook with its SkyDrive cloud storage and added support for SMTP send, which makes it easier to send a message from an alias. Microsoft, which dominated the work email landscape with its Exchange Server and Outlook combo, is facing really tough competition as Google Mail and Google Apps have taken hold. microsoft outlook This story was updated at 10:37 a.m. PDT to correct the number of Outlook.com users. The 400 million count used earlier represents more than 300 million active Hotmail accounts plus new customers.

    I have been using Hotmail nearly since it’s inception. The first few upgrades were definite pluses. The “upgrades” that have occurred over the past 4-5 years have been getting progressively worse. They took a simple user friendly interface and bloated it to the point of unrecognizability. They unfortunately felt compelled to try to force social BS on us and constantly changing the interface. I’m tired of it. Now that I’ve had a steady job and don’t have my name/resume out there any longer with my hotmail address, I think I will pull the plug, once I’ve had a chance to download my content. I’m forced to use the Outlook crapware at work since the state I work for got rid of Novel Groupwise a few years ago. That was a much better program, especially for any power users; Outlook brought a significant loss of unique features and rarely a day goes by where I’m not cursing a MS product, especially that stupid effing piece of S… ribbon.

    They sure migrated me…to gmail!

    I was a hotmail user for almost 13 years, but the constant changing of interfaces the last few yars really annoyed me. But now they go and decided to change even the freaking name? WTH Microsoft, I’m not going to use that thing you call an operationg system, stop pushing it!

    Yes, they have migrated us to Outlook–which sucks. It’s harder to use than Hotmail and not having a choice in the matter just added insult to injury. Way to go Microsoft.

    Impressive, I definitely think the new Outlook interface is an improvement over the old Hotmail.

    1. Hotmail to Outlook is foolishness!! I cannot access my hotmail emails with this foolish new outlook. You must be one of the few persons who had no problems with outlook.

  6. Hotmail was OK. Outlook sucks. Period!

  7. Well considering I see new emails coming through to my Hotmail account but can’t reply, forward or create a new email, I’m not exactly happy. Didn’t work last night, didn’t work this morning. Not sure what to do to remedy it but if it isn’t working soon, bye-bye Outlook.

  8. It is not sorted out. It takes me forever to get into Hotmail. to the point where I have to stop trying to get in. try again. stop. try again. takes AT LEAST 5 attempts to get in. sick of it now. Sort it please

    1. I have exactly the same problem. If Hotmail doesn’t resolve the problem…I’m going to Yahoo, My spouse left Hotmail abut 7 years ago because of constant problems with it.

  9. now I can’t log onto my old hotmail account!

    It’s alright for you computer literate people to ride roughshod over the likes of myself. I have used Hotmail for many years, yet I am not against change. However I requested your help several days ago, but alas, non was forthcoming. All I want is someone to spell out in plain English what I am doing wrong.I am sending Emails but everyone is telling me that they are arriving blank. Please, if someone can take the time to send me an email giving me some help, I will be eternally grateful. Thank you.

    Yours faithfully
