You should start by reviewing how and where the script stores the credentials. Make sure that it sees the correct password.

Then work with your SMTP (Exchange?) server admin and have him test those credentials. Verify that no other access permissions were changed.

Your image shows a "535 5.7.139" error. There are some hits on the net that describe how to troubleshoot that error.

Is this a domain account? Does it have any logon restrictions? Another thought that I had was to try map a network drive with those credentials and see if it can authenticate to some server or domain controller.

net use x: \\someservername\ipc$ /user:yourdomain\youruser net use z: \\somedomaincontroller\sysvol /user:yourdomain\youruser

That would verify that you have the correct password.

it is a team Distribution List email ID. It is working fine if I use Get-Credential. Since the Get-Credential prompt to enter the password every time, looking for work around for automation.

Get-Credential will always work. It's when you try to use that variable to authenticate to some resource will you find out if it's valid or not.

Maybe have your Exchange admin change the password again and have him type it in very carefully. Then try that new password.

Here is an example of using a credential object in a script. The account is named admin and its password is also admin.

$script = 
 {
    "This script is running on {0}" -f $env:COMPUTERNAME
    ""
    "**** Calling whoami to execute on the remote system"
    c:\Windows\system32\whoami.exe
 }
 $User = ".\admin"
 $PWord = ConvertTo-SecureString -String "admin" -AsPlainText -Force
 $Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, $PWord
 Invoke-Command -ComputerName "test10b" -credential $Credential -ScriptBlock $script
