How to pass credentials to the Send-MailMessage command for sending emails

Question

I m having difficulty passing my credentials to the Send-MailMessage command  This is what I am running   Send-MailMessage -smtpServer smtp gmail com -from  myself gmail com        -to  myself gmail com  -subject  Test  -attachment C  CDF pdf   it errors with below the message which is obviously because I have not passed my gmail credentials  Send-MailMessage   The SMTP server requires a secure connection or the client was not authenticated  The server response was  5 7 0 Must issue a STARTTLS command first    I googled a bit and also went through the man page of Send-MailMessage and found that the  -credential  parameter needs to be passed   My issue is  HOW    I tried with Get-Credentials as below    mycredentials   Get-Credential   Then entered my usrname and password for gmail in the box that pops up   then I run below command   Send-MailMessage -smtpServer smtp gmail com -credentail  mycredentials     -from  myself gmail com  -to  myself gmail com  -subject  Test  -attachment C  CDF pdf   and still it fails with the exact same error   So I need help from you guys on how do I pass my Credentials to the Send-MailMessage command  I learned about PScredentials but not exactly sure what it is and how to use it in this context

PSH   cred   Get-Credential      PSH   cred   Export-CliXml c  temp cred clixml      PSH   cred2   Import-CliXml c  temp cred clixml   That hashes it against your SID and the machine s SID  so the file is useless on any other machine  or in anyone else s hands

in addition to UseSsl  you have to include smtp port 587 to make it work   Send-MailMessage -SmtpServer smtp gmail com -Port 587 -Credential  credential -UseSsl -From  yyy gmail com  -To  xxx email com  -Subject  TEST

I found this blog site  Adam Kahtava I also found this question  send-mail-via-gmail-with-powershell-v2s-send-mailmessage The problem is  neither of them addressed both your needs  Attachment with a password   so I did some combination of the two and came up with this    EmailTo    myself gmail com   EmailFrom    me mydomain com   Subject    Test    Body    Test Body    SMTPServer    smtp gmail com    filenameAndPath    C  CDF pdf   SMTPMessage   New-Object System Net Mail MailMessage  EmailFrom  EmailTo  Subject  Body   attachment   New-Object System Net Mail Attachment  filenameAndPath   SMTPMessage Attachments Add  attachment   SMTPClient   New-Object Net Mail SmtpClient  SmtpServer  587    SMTPClient EnableSsl    true   SMTPClient Credentials   New-Object System Net NetworkCredential  username    password      SMTPClient Send  SMTPMessage    Since I love to make functions for things  and I need all the practice I can get  I went ahead and wrote this   Function Send-EMail       Param            Parameter               Mandatory  true            String  EmailTo           Parameter               Mandatory  true            String  Subject           Parameter               Mandatory  true            String  Body           Parameter               Mandatory  true            String  EmailFrom  myself gmail com     This gives a default value to the  EmailFrom command          Parameter               mandatory  false            String  attachment           Parameter               mandatory  true            String  Password                 SMTPServer    smtp gmail com            SMTPMessage   New-Object System Net Mail MailMessage  EmailFrom  EmailTo  Subject  Body          if   attachment -ne  null                 SMTPattachment   New-Object System Net Mail Attachment  attachment               SMTPMessage Attachments Add  SMTPattachment                     SMTPClient   New-Object Net Mail SmtpClient  SmtpServer  587            SMTPClient EnableSsl    true           SMTPClient Credentials   New-Object System Net NetworkCredential  EmailFrom Split      0    Password             SMTPClient Send  SMTPMessage          Remove-Variable -Name SMTPClient         Remove-Variable -Name Password     End Function Send-EMail   To call it  just use this command   Send-EMail -EmailTo  Myself gmail com  -Body  Test Body  -Subject  Test Subject  -attachment  C  cdf pdf  -password  Passowrd    I know it s not secure putting the password in plainly like that   I ll see if I can come up with something more secure and update later  but at least this should get you what you need to get started   Have a great week   Edit   Added  EmailFrom based on JuanPablo s comment  Edit   SMTP was spelled STMP in the attachments

So  it was SSL problem  Whatever I was doing was absolutely correct  Only that I was not using the ssl option  So I added  -Usessl true  to my original command and it worked

It took me a while to combine everything  make it a bit secure  and have it work with Gmail  I hope this answer saves someone some time   Create a file with the encrypted server password   In Powershell  enter the following command  replace myPassword with your actual password     myPassword    ConvertTo-SecureString -AsPlainText -Force   ConvertFrom-SecureString   Out-File  C  EmailPassword txt    Create a powershell script  Ex  sendEmail ps1     User    usernameForEmailPassword gmail com   File    C  EmailPassword txt   cred New-Object -TypeName System Management Automation PSCredential -ArgumentList  User   Get-Content  File   ConvertTo-SecureString   EmailTo    emailTo yahoo com   EmailFrom    emailFrom gmail com   Subject    Email Subject    Body    Email body text    SMTPServer    smtp gmail com    filenameAndPath    C  fileIwantToSend csv   SMTPMessage   New-Object System Net Mail MailMessage  EmailFrom  EmailTo  Subject  Body   attachment   New-Object System Net Mail Attachment  filenameAndPath   SMTPMessage Attachments Add  attachment   SMTPClient   New-Object Net Mail SmtpClient  SmtpServer  587    SMTPClient EnableSsl    true   SMTPClient Credentials   New-Object System Net NetworkCredential  cred UserName   cred Password     SMTPClient Send  SMTPMessage    Automate with Task Scheduler   Create a batch file  Ex  emailFile bat  with the following   powershell -ExecutionPolicy ByPass -File C  sendEmail ps1   Create a task to run the batch file  Note  you must have the task run with the same user account that you used to encrypted the password   Aka  probably the logged in user   That s all  you now have a way to automate and schedule sending an email and an attachment with Windows Task Scheduler and Powershell  No 3rd party software and the password is not stored as plain text  though granted  not terribly secure either    You can also read this article on the level of security this provides for your email password
