Hotmail was an email service offered by Microsoft, which is now rebranded as Outlook.com. Unfortunately at present there is no UK phone number dedicated to helping Outlook.com account holders, however you can click here to contact a Microsoft Live Chat agent or phone Microsoft’s general technical support helpline number 0344 800 2400. Furthermore you can contact their customer service team by calling 0870 042 1041, which is charged at a rate of 13p per minute from landlines as well as a set connection charge.
There is also the option to use Microsoft’s general application enquiries and support page at this address: https://support.microsoft.com/en-us/contactus
Outlook.com was launched in 2013 from the email framework of Microsoft’s Hotmail service. It is sometimes considered a customer service add-on, given the support present in Microsoft’s Windows and Outlook Express software.
