Add a carriage return in a .csv file

Question

I running the following command which works but I would like to format the output in the CSV file. The "SecondaryAddresses" field is where my issue is. The field contains multiple addresses as such:
{[email protected], [email protected], [email protected]}
Current output in .csv file.
Desired output in .csv file.
I want to be able to add a return into the .csv file so the data is in one cell.
Get-Mailbox jblake -DomainController "DC01" -ResultSize Unlimited | Select-Object DisplayName,alias,PrimarySmtpAddress, @{Name=“SecondaryAddresses”;Expression={$_.EmailAddresses | Where-Object {$_.PrefixString -ceq “smtp”} | ForEach-Object
{$_.SmtpAddress}}}

Answer 1

I think that is still not quite there, it is missing the filter on PrefixString.
Get-Mailbox jblake -DomainController "DC01" -ResultSize Unlimited | Select-Object DisplayName,alias,PrimarySmtpAddress, @{Name=“SecondaryAddresses”;Expression={($_.EmailAddresses | Where-Object {$_.PrefixString -ceq "smtp"}).SmtpAddress -join "`n"}}
Enclosing $_.EmailAddresses | Where-Object {$_.PrefixString -ceq "smtp"} in parenthesis lets us use the dot operator on the array that it returns. Accessing a property on an array that is actually a property on each of the objects in the array
should return an array of those property values (an array of SmtpAddresses), which we can then -join with the newline character. Note that this feature of arrays was added in v3.0 so in case you're on an older version this wouldn't work.
I also don't have the Exchange cmdlets, so I unfortunately I cannot test it either.
