Hi,
>> Can I just unstall it? I don't want or need it.
There are indeed some links on the website, which will open Outlook when you click. Such as Mailto link. If you don't like this, it is suggested to set to prevent your browser from opening applications on your computer (Specific settings depend on your browser).
Or just avoid clicking on these links。
>> I don't want there to be confusion between my Yahoo mail and Outlook--if I have to have it.
Do you mean that you have configured both your Yahoo mail account and Outlook.com account on your Outlook desktop client? If so, and you don't want to put the folders of these two accounts together, it is suggested to configure them in
different profiles. Or just configure only one eamil account on your Outlook client.
Hope this can be helpful.
Regards,
Aidan Wang
