Many copies of sent emails

When I send an email, sometimes up to 5 copies of the sent email appear in the sent items folder.

It’s probably a server issue.

When you send a message, eM Client waits for confirmation from the server before deleting it from the Outbox. If the server doesn’t respond correctly then it is uploaded again.

If you have a paid license, and can reproduce it, I suggest you open a support ticket and we can look at some logs to see what is happening.

When do you have time to controle?

I have this problem also.
