Bests & Worsts Reviews from Amazon

I have attempted logging in with the correct password for my outlook and gmail-outlook linked accounts, but was met with an invalid error message about my Wi-Fi connection. I restarted my tablet, uninstalled and reinstalled the app multiple times, changed my Wi-Fi connection from my home to my cell phone, but still the same error. I know it is not an issue of an incorrect password because I purposefully entered it in to see if it would give that specific error message, which it did. When I continued to use the methods described earlier using my correct password, I was simultaneously able to download another app, Microsoft Outlook, with a secure mobile connection, but still, this app says it is unable to proceed because there is not a secure connection.
