Hello there again br 9.

You can also turn your spellcheck program on and off. And auto correct it. Windows 10 and Thunderbird is required.

Open Windows Settings. Press the “Start” button, then click the settings cog in the bottom left corner, above the power button. Click the “Devices” heading. Open the “Typing” menu and turn on or off Windows 10 spell check and Windows autocorrect.

If spellchecker is also grayed out and does not work the fix is down here.

Read carefully before using it.

First, launch Thunderbird.

Next, enable the Menu bar if you have not already. To do so: click the Menu button near the top right of the Thunderbird window, then click Options, then place a check mark beside "Menu Bar". You should now see the menu bar at the top.

Now it's time to download a dictionary. Click Tools -> Options, then go to the "Composition" menu at top of the Options window, then click on the "Spelling" tab.

Under the "Spelling tab" you should see: "Enable spell check as you type" and it should have a check mark beside it. If your "Language" pull-down option is grayed out, then will need to download and enable a dictionary. Click the "Download more Dictionaries" link. This will open up a new tab in Thunderbird; in order to access that tab you will have to close the "Options" window. Do that and you should be able to access the "Dictionaries" download page.

Click the link to download the "English (US)" dictionary (or whichever dictionary you prefer). A new window will appear, click the "Add to thunderbird" option, then "Install now".

At this point, Thunderbird will report the dictionary was installed at the very top of the screen. Near the very right of that is an option to click that says: "Add-on manager" - click that button.

The "Add-ons manager" tab will appear and you should see a "Dictionaries" heading on the left side of the window, with the dictionary you installed on the right. Now it's time to verify that the dictionary is selected for use. Click Tools -> Options from the very top, then go to the "Composition" menu, then select the "Spelling" tab. It should say: "Enable spell check as you type" with a check mark, then underneath that: "Language: English (US)", or whichever language you specified.

Now it's time to test your spell check. Close all the Thunderbird tabs except for the main Thunderbird window. Next, click the "Write" button to create a new email, then enter in some text with some incorrect spelling to test your real-time spellchecker. It should work.

End
