Are you looking at the Correspondents column? It is a fairly new column that displays both inbound and outbound messages.

As far as I can tell, this has nothing to do with the column. It's in a different folder altogether. Plus, I have eliminated the correspondents column and restored the "from" and "recipient" columns.

What I am talking about is entirely new behavior, where there are now two copies of every message I send, in two different folders: both in the sent folder and in my inbox.

It must be some setting, possibly even on Gmail, since it's happening in only one account and not in others.

perhaps you could assist by posting the two other topic you mention. Is this some gmail peculiarity perhaps. Or a result of a common anti virus product.

Given it is very rare. you say three people. Diagnosis would almost certainly involve looking at similarities in systems, software and add-ons.

From what you say, no one has any idea what the cause is. So this is a search operation not a click here and it will go away thing.

Here is more information in case anyone can help.

I have 3 different accounts that I use. 2 of them are on the same domain, and the third is another domain. This problem only happens in one of them. I just tried to change the setting for a moment, removing the "keep a copy in the folder" setting, and for keeping a copy of the sent message at all. Nothing affects it. ALL messages I send now have a copy in the Inbox, and only for one account.

Is there anyone who can help?

Is this for new 'Write' emails or 'Replies' or both ?

Does that account have an auto Cc for emails?

• Account Settings >Copies & folders
• uncheck 'Cc these email addresses' .
• click on OK

Check this out in the gmail webmail account: When you use a filter with the "never send to spam" option enabled that is matching the message you send, they will show in the Inbox.

Gmail webmail account may also have a setting for 'Conversation View'. Go to the main Settings page, look for the “Conversation View” section, select the option to turn it off, and save changes.

this is the piece that solved it. somehow, a filter got added that said every message from me to never send to spam, and that's how it happened. i am SO relieved, thank you so much.

I DON'T HAVE A GMAIL ACCOUNT - and I am getting copies of EVERY EMAIL I SEND OR REPLY TO. This started a couple of weeks ago -- before the last upgrade. I DO NOT have the box checked to cc me on all emails. How can I get this turned off? Thanks! Linda

Oh I see you have... Please don't spam other peoples support topics with your own issues. It just confuses the issues. Thank you.

I haven't received a reply on either of my questions --- how to eliminate unwanted copies of sent or 'replied' email, and how to send video with built in links. Do I need to re-post these separately?

I began to have this problem, it seems, with the latest update. Besides sending a copy to my 'Sent' folder, I'm also getting a copy of emails I send in my 'new' emails...so I'm getting 'double' copies. I normally move all 'important' emails to a named folder, for storage and reference. I work at home - gets lots of emails - and now have to check to see if I have a copy of an email already in a folder - or if this is just an 'extra copy' I didn't need that was sent anyway. I'd also like to be able to copy and send videos on current news to friends - which include a screen shot of the video and a live link. This ability was removed from Tbird some time back, for some reason. I currently have to do copy the screen shot, then put 'LINK TO VIDEO:.............' with the url, below the video - instead of making the video itself 'clickable'. How can I make them clickable? Thanks for all the hard work you all do!

@CuriousQ

Perhaps no one has an answer or the time to respond. I know I don't.

I have had the same issue with all my original emails not doubling up. But all my reply messages doubling up. This has been going on since 12-07-2018.

   I checked my account settings as suggested above. My cc  these emails is not checked. 
   I can delete one of the duplicated emails, but really not a time option. 

Anyone find an answer to this yet?
