Easy way to replace PowerShell Send-MailMessage functionality?

Question

Recently all my PowerShell scripts that use "Send-MailMessage" stopped working because because Microsoft stopped supporting basic authentication. I've looked at replacing the old code with an app password or with Microsoft Graph. The documentation I've seen is more complicated than I can grasp. I dabble with PowerShell, but I'm not a real developer. Can someone provide the code and steps required to translate the old syntax into something that will work? I don't really care which method I use. Here is an example from one old script that sends email when an error is found in a log file. Thanks.

Send-MailMessage -UseSsl -Body "Check \computer_name\share_name\log.txt for errors." -From $FromAddress -SmtpServer $SMTP_Server -Subject "Error found in log file" -To $ToAddress -Port $Port -Credential $smtpCred

Answer 1

Try using MailKit and MimeKit.

mailkit
Or, using NuGet: MailKit

MimeKit
Or, using NuGet: MimeKit

I had a problem installing them, though. There's a problem with a circular dependency. Just install MimeKit first. If that goes okay, install MimeKit and use the "-SkipDependencies" switch. If you have a problem installing MimeKit, use -SkipDependencies on that install, too.

Answer 2

There is no associated PowerShell module or cmdlet (from Microsoft) that uses MailKit. Using MailKit to send e-mail is somewhat like what you had to do before there was a Send-MailMessage cmdlet.

Here's a link to an example: powershell-email

The documentation for the module on GitHub might not be up-to-date with the most recent version, and the examples are in C# (but pretty easily transported to PowerShell): Examples

There's also this module: 3.0.0
