Windows 10 Mail App stopped syncing with Verizon business

I had been using the Windows 10 App successfully for several months. I hadn't opened it from December 24 until yesterday. Now it has stopped syncing with my Verizon business account. I tried setting up the account on my Outlook 2010 which is what I use for all other email, but couldn't do that either - so maybe it is a Verizon problem & not Windows 10 but I doubt it because Windows 10 has messed up just about everything else that has gone wrong.

Any advice would be appreciated. I would rather use the mail App because it keeps everything clean & separated for my purposes. Thanks!

SMH, found the solution to this when I set up calendar. There are two places to set privacy for the Mail and Calendar Apps. Here is where I found the info: Mail and Calendar for Windows 10 FAQ - Outlook.

Click the Start icon, then settings. Select privacy, then calendar. Under Choose Apps that can Access Calendar, Mail & Calendar should be set to "on". Same under email privacy.

Windows 10, you may try, but you will not destroy me!
