Emails from nobody@invalid.invalid cannot be deleted

Using version 9.2.1222

Today one of the emails I sent in 2012 turned into an email from nobody@invalid.invalid and I cannot delete it.

What needs to be done?

no answers to my question/issue?

If the message can’t be deleted then it may be some minor database corruption.

Please close eM Client and open a Windows Command Prompt. Not a powershell, but a command prompt.

Paste in this command:
"C:\Program Files (x86)\eM Client\MailClient.exe" /dbrepair

When that is done, restart eM Client.

Good evening

Thank you for your answer. I ran the command prompt as administrator (not the poweshell) but unfortunately it did not work.
