Windows 10: WLM sending duplicate emails

When sending emails in WLM set up for IMAP I am getting the following error? The emails remain in the "Outbox" and then when they are fnally sent they are sent two or three times???

Can anyone provide some assistance as to why this is going on all of a sudden?

Thanks

Send To > Mail Recipient Problem Windows 10

Well that's damn confusing because from the emails Microsoft keep sending me about this they make it seem that if you are using WLM that you will not be able to send or receive email from the WLM after the 30th june.

Also they still doesn't solve the original problem of not being able to send anything by the send to mail recipient, but thanks for clearing that up (if your right that is) guess I will know in the next couple of days

 

How to stop WLM and set Win 10 Mail as default?

For years, I used WLM and it appeared as an option in the right click menu. So, if I wanted to send a file by email, I would point to it, right click and chose "Send to default mail recipient" and the file would be sent by WLM. Now I have the Win 10 Mail
as my default mail client, however, the WLM still is the only option in the right click menu...
