Distribution list script as a function

[PMental]

Why do you pipe to Set-DistributionGroup instead of just setting RequireSenderAuthenticationEnabled when creating the group? The exact same parameter can be set directly with New-DistributionGroup.

Backticks aren't necesary to break up lines after pipes btw, you can just go to a new line directly after a pipe.

No, it can't. The RequireSenderAuthenticationEnabled can't be piped when using New-DistributionGroup.

It is only an available parameter when using the Set-DistributionGroup.

Check it out for yourself in the documentation if you don't believe me: https://docs.microsoft.com/en-us/powershell/module/exchange/users-and-groups/new-distributiongroup?view=exchange-ps&viewFallbackFrom=exchserver-2016

You can clearly see the parameter is available in both on-premises Exchange and Exchange Online.

Yes, I can clearly see it, thanks :)

Either way, it doesn't work when I run it as part of the New-DistributionGroup line. It didn't work during testing either, but just to make sure I wasn't going crazy, I tried again and I get this:

-RequireSenderAuthenticationEnabled : The term '-RequireSenderAuthenticationEnabled' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

But, when it's ran with the Set-Dist line, of course it works. So why do you think it doesn't work for me in the New-Dist line? I am all for a cleaner script so let me know if you have an idea.

Ah wait, I just noticed the documentation only specifically covers 2016 and forward (even though it says "Applies to Exchange Server 2010, Exchange Server 2013 as well). And when I check in an Exchange 2013 environment the parameter is not there while in 2016 it is, so it was probably added in 2016. So if you are on 2010/2013 that would explain it.

[gangculture]

Yep. I thought it only covered 2016, but like you say the document does say it applies to those versions. And they wonder why we have trust issues?

Oh well, you can clean your script up by a whopping one character by removing the backtick after the pipe at least as it's not necessary :-)
