recipient error, sending of new email failed due to the error

I cannot send emails, because one recipient in the past was not valid. This blocks most of my new messages. How do I delete that?

Hello Magdalena,
I suspect there might be a message stuck in your outbox.
Check the File>Work offline option to stop eM Client from synchronizing for a while.
Restart eM Client.
Check Outbox and delete any messages from here.
Turn eM Cleint to Online regime again and see if the issue persists.

If it does, please open the third tab in the Operations window and copy the content of the Log tab.

Regards,
Olivia

I have a same problem

hi Olivia,

I have no messages in my outbox, it is empty. I tried what you have suggested, but it did not work. I do not understand the part about “cope the content of the Log tab”. Can you explain please?

Hi Magdalena,
when this error appears, go to Tools>Operations>Log tab.
Click inside, hold Ctrl+A to Select all, Ctrl+C to copy and then paste the text here on the forum using Ctrl+V.

Regards,
Olivia

 is that enough? the rest of the log was about synchronizing folders etc

Did you get any feedback on this?

Bump.  I’m getting the same situation.  Nothing in the outbox folder but the same error: Note that is says “@team-commercial.com” without any head.  The inbox is empty.  I’m reinstalled.  I’ve checked the outbox on OWA.  WTF?

I guess you tried Olivia’s comment about setting eM Client to Offline, and that did not help.

To do a clean install without the user data you also need to delete or rename C:\Users\yourname\AppData\Roaming\eM Client. Actually, no need to uninstall eM Client, just delete this directory and setup your account when you start up. Or go to Menu > Tools > Accounts and delete the account that way.
