Changing Thanks to Thanks and Greets - OUTLOOK 2016

Hmm, seems like somehow you have either modified an Autocorrect entry or accidentally created an autotext. Go to File>Options>Mail>Spelling and Autocorrect and see if there is a rogue entry in there for Thanks!

Check as per above.

Certainly an update did not cause this.

Try typing:   Thanks for this      What happens?

When I type THANKS it has "HIT ENTER FOR THANKS AND GREETS"     Thanks for this...  Nothing happens..   I am not the only one with this same problem...

Perhaps on one problem machine with few Autocompletes, clear Autocomplete, restart and test.

It does appear to me and the expert above that it is an Autocomplete issue.

Try it and see.

This sure sounds like an Auto Correct issue to me as well, though I wouldn't rule out updates as the cause just yet. The last bunch of Office Updates I installed re-enabled Addins I had disabled and even caused some to be resinstalled that I had completely removed from Outlook! (Winzip Courier was re-added just as an example)

What version and build is your Outlook 2016? Click File > Office Account in Outlook?

What does it say for "Version" and "Build" to the right of the "About Outlook" icon?

Apart from that, Auto Correct is the only thing I can think of, so also suggest checking that as per Karen Falandays comment. Just type "Thanks" in the replace box and see what entries are there.

Version 1803 ( Build: 9126.2295) - -   Nothing shows up in the replace box when THANKS is typed.

Version 1803 ( Build: 9126.2295)

Hmm. I was expecting yours to be higher than mine. I'm on Version 1809 (Build 10827.20150 Click-to-Run) so that still doesn't rule out this being caused by an update to my mind.

Nothing shows up in the replace box when THANKS is typed

Nothing at all? You don't get something similar to below? The highlighted is a default entry and should be there on yours?

Sorry.. I meant.. nothing as in THANKS and Greets doesnt show up.

This could be an addin that got installed. You don't have something similar to this installed do you?

Close Outlook and restart in Safe mode

Windows Key + R
Outlook /Safe

Try it now. Does it still happen?

Does not do it in safe mode.   I do not have any add-in running in Normal mode when it happens.

Ok, if safe mode cures it, then we're getting closer. Auto Correct will still work in Safe mode, so that rules that out as a cause.

Just humor me for a moment and do the following;

Right-click your Outlook icon and select "Run as administrator"
Click File > Options > Add-ins

Take a screenshot and post it in your next comment.

The same thing happened to me.   I believe an add-in called KuTools may have inserted this..
Here is the fix

Open a blank email
Click the Insert Tab on top
Click the down arrow on "Quick Parts" and then view the Auto Text entries.  You will see an entry for "Thanks and Greets"
Right click on the entry for "thanks and greets" and choose organize and delete.
Delete the entry in the "building blocks" column

TEGTGI, if you read the previous comments, you will see that's already been covered. This issue has nothing to do with Auto Text.

Auto Text and Quick Parts are different features.  I did NOT see "Thanks and Greets" in my auto text...I DID see it in Quick parts.
