I try to send mail with Send-MailMessage cmdlet in PowerShell_ISE and it works perfectly,
but when i run same PS script in a scheduled task with PowerShell I get error with the following
text:
Transaction failed. Server responded: 5.7.1 (Unknown [x.x.x.x] ) : Client host rejected : Access denied
In ISE environment - sending mail works perfectly......
How does the script authenticate to the email server? What account is the scheduled task configured to run as?

Are you running the ISE and the scheduled task on the same machine?
Are you the admin of the mail server you're using as the SMTP server? Are there restrictions in place to allow only certain IP addresses to use the SMTP server? Is the IP address "x.x.x.x" in the SMTP server's "5.7.1" status response one of the allowed (or perhaps the restricted) list of addresses?

The user on ISE and scheduled task are the same and it is running on same machine....
I am not admin of the mailserver - the mail server is an external SMTP server with basic secure authentication....
As ISE works then I may suppose that the scheduled task also should work - the have same IP/User ?

Then then you must have done something in your interactive session to authenticate to the SMTP server.
In your script add your credentials.
Unless you're providing a credential in the Send-MailMessage cmdlet you can't depend what information is presented when the server asks for authentication.
If the connection isn't using SSL (which only you know since you've not provided any information other than that you're using Send-MailMessage), I'd start troubleshooting with something like WireShark to grab the exchange between the client and server. Compare the two (one that works, one that doesn't).
You could also ask the admin of the mail server why you received the rejection. Provide with the time, date, your IP address, and the rejection information, they may be able to explain the problem.
Hello
Thank you for your question and reaching out. I can understand you are having issues related to Email sending.
Please verify Task Scheduler run as account has proper permission to run the script and send the email.

The Task scheduler is running with same user as in ISE - and it is an admin user.... (Local account)
