Re: Outlook will not send only receive

Is the your own private email account or an Optus one and are you connected to Optus when trying to send mail?

@linda123456 Have you googled the error and tried any of the solutions?

Does your device have another application that you can setup email to do some testing or maybe try setting up a new email account in Outlook?

Re: Outlook will not send only receive

What is the name of the outgoing server you are using and what port number?

Re: Outlook will not send only receive

Microsoft tried setting up a new email and unable to do the same, they got same error code. After 2 hours on the phone discovered I was the 6th caller today with same issue. I was told it’s a server issue!
Spoke to Optus they said no it’s not.

I have googled it and it’s a similar issue with gmail as well. But can’t be fixed unless Optus acknowledges the issue!

I understand and there might be a workaround if you tell me what outgoing port you are using.

Re: Outlook will not send only receive

If you have authentication ticked for your outgoing mail server have you tried unticking it? Do you use any programs or addins or plugins that may interfere with Outlooks operation?

Edit: You didn't add a VPN or new antivirus recently?
