"Outlook is not the default mail client" warning

    Question

  • Hi,

    I always use Outlook as my default mail client. However, from time to time, when I start Outlook, I will get a warning said "Outlook is not the default mail client" and I need to reset it as the default client again and again.

    Why?

    Thanks

  • Hi hzsl,

    >> when I start Outlook, I will get a warning said "Outlook is not the default mail client"

    Is this the entire error message?
    What's the version of your Outlook?

    Please try referring to the above link provided by Clark and check the default email client via registry.

    If you still have concerns on this, please post back at ease and we are glad to help you.

    Best regards,
    Yuki Sun
