Hello,
There is a particular contact to whom I cannot send emails from Outlook.
As soon as the email is "sent," I already receive a message from "System Administrator" telling me that it cannot contact the recipient with the error code:
503 Bad sequence of commands
Do you know what I need to do? It works with Gmail.
I have tried SMTP with and without SSL (I am using POP3 with 1&1).
Thank you for your help!

Hello
Try repairing Outlook as follows:
Right-click on the Windows logo and select Run
Type Outlook.exe /safe then click OK.
Uncheck all the checkboxes in the list, then click OK.
Restart Outlook.
If the problem does not occur after restarting Outlook, one of the add-ins is probably causing the issue. Restore the add-ins one by one until the problem occurs to determine which add-in is causing the issue.
To reactivate these add-ins one by one, test each time you activate an add-in so you can identify which one is causing the crash.
Best regards

Avoid installing these free software programs that supposedly boost or repair your PC; they are of no major utility. The best tools in Windows are its own tools like ...Dos..&.. PowerShell

Check the SMTPGATE.LOG file to find the offending command that caused the error.
