HELP - Windows 10 changed my default mail app
Windows 10 recently added a new feature that allows you to set the default mail app. Unfortunately, it was set with a default to use the Windows 10 Mail app. But what if you prefer to use another mail app such as Thunderbird or Outlook? No problem, simply right click on START (lower left windows icon) and then click on SETTINGS. In settings click on DEFAULT APPS and then click on the Email icon. A drop down list will open up and you can choose the email app you prefer. (To get to SETTINGS you can also left click on the START icon and then click on the GEAR icon.)
HELP - Emails aren't showing up in my Inbox
Sometimes emails sent from a website don't get downloaded to your phone, iPad, tablet and/or laptop email client. You check your local junk/spam folder but they're not there.
The problem may be that they have been placed in a Junk/Spam folder located on the remote mail server that is not accessible by your local mail client. In order to access them you may need to go online to (to MSN.com or Google.com or to webmail.YourDomain.com) to access the mail server and clear up the problem there. Then the mail will be delivered to your local device, and hopefully future emails of the same type will also be delivered correctly too.
Sometimes it also helps to add the sender (or the sender's domain) to the Safe Sender List maintained on the mail server.
Here's the instructions on how to do the above:
