Using classic Outlook for Windows in business environments
Hi John, my name is Neil, and I'm an Outlook user like you.
Sorry you are receiving these error codes.
In this particular instance, if you are sure your Outlook account details are correct, try contacting Outlook support.
From within the Outlook App, click on the "Help" tab.
Then click on "Contact Support".
A side bar will open up on the right hand side, where you can describe your problem and even include a screenshot of the current screen (probably best to get the error up on screen first if you can). Click the "Submit" button to send your support request and someone from Outlook Support will contact you to help resolve the issue.
I hope this helps.
Kindest regards,
Neil
