UNABLE TO SEND EMAIL USING GMAIL ON THIS PC, OUTGOING EMAIL GO THE TO SPAM BOX

Hi Mary. I'm Greg, an installation specialist, 10 years awarded Windows MVP, and Volunteer Moderator, here to help you.

Are you using the Windows 10 Mail app or Office Outlook?

WINDOWS 10 MAIL APP REPAIRS:

I'll give you all fixes for the Mail apps so that at least something will work. Even if you've tried some please go through in sequence as possible:

What often works is to go to Windows 10 Mail Settings (gear icon at bottom of Inbox) then Manage Accounts, then choose the problem account(s), then Delete the Account.

Restart PC and retrace that path to add the account back. Make sure the Sync settings are as desired for how far back you want mail Downloaded from, whether to include Calendar and Contacts (People app). See this setup guide to make sure you get everything set as you like: https://www.windowscentral.com/how-get-started-...

If that's not enough then Reset the Mail app at Settings > Apps and Features > Mail & Calendar > Advanced Options > Reset. Restart PC. Try adding the accounts back to see if it works now.

If that fails to fix it then Re-register Mail & Calendar app from Option 2 here: http://www.tenforums.com/tutorials/3175-apps-re...

Finally if nothing else works uninstall the Mail and Calendar app App Settings above, restart PC, then reinstall it from MS Store Hub (three dots at top right of Store app) > My Library.

If you have broader performance problems go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files. Then continue with the other steps to go over your install most thoroughly.

If nothing else helps then run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This solves many problems and will also bring it up to the latest version which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m...

OFFICE OUTLOOK REPAIRS:

Repair Office by one of these methods:

If that's not enough reinstall Office, with a PC restart after uninstalling and before reinstalling:
