Microsoft announced on Friday that it has finished transitioning all of its Hotmail users over to Outlook.com, which is now home to more than 400 million active users. Of those 400 million active users, 125 million are accessing most of the services on a mobile device using Exchange ActiveSync, the company said.
Outlook.com made its public debut last summer as a new metro-inspired email service and was most recently updated with integrated Skype support. It’s receiving yet another upgrade today: the integration of SkyDrive into Outlook. Customers can now select files from SkyDrive to use as attachments. The option is rolling out today but will hit all users around the globe in the coming weeks.
Microsoft said that it needed to migrate 300 million existing Hotmail accounts over to Outlook.com, which meant shoveling about 150 million gigabytes of data (150 petabytes) in six weeks. The company is confident that former Hotmail fans will soon favor Outlook.com and said that it appreciates the feedback it has received from customers so far.
