    windows Mail App started sending from outlook_[number]@outlook.com which doesn't exist


    HiI've configured a new computer for my mum, Windows 10 Home, all updates installed. I added her ISP email into the Mail app using IMAP, details provided by the ISP. This all worked fine. Tonight, her emails are suddenly coming from an account outlook_[number]@outlook.com, to which all replies fail. Previous emails from her were correctly from her ISP email address literally 10 mins between when it worked, and when it stopped working.I found an MS Support post with a similar issue when using Outlook.Outlook.com email account appears as "outlook_[long series of letters and numbers]@outlook.

    :)

    Windows doesn`t start. Authomatic repair doesn`t work.

    Thanks again!!

    I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

    I`ll do it and I`ll be updating this thread when I have the report.

    I ran SeaTools. These are the results:

    Does it mean my HDD is useless?

    Make 'Mail' app default for sending emails and not Outlook


    I have both the windows 10 mail app and office outlook installed but when emailing a document from within windows file explorer it always tries to send it using Outlook.

    Is there a way to get it to default to send using the Mail app instead?

    I have tried setting the default app as mail in the Default Settings but it keeps trying to send from outlook.
