    Hi, 

    I have this 

    $test1=import-csv -path "FilteredMailboxes.csv"
    $test2=import-csv -path "ReportingUsers.csv"


    compare-object $test1 $test2 -property "mail" | export-csv 'test3.csv' -notypeinformation

    This is only getting me uncommon users between 2 CSVs. 

    I have an Exchange online script which update Group Membership every night. Currently I remove all members and add new members which takes a very long time. 

    To minimise time, I want to compare current members with new members and Output only new members. 

    Also if possible i want members which are not part of new membership be removed. 

    So compare 2 CSVs and:

    1. Output 3rd CSV with new members

    2. Output 4th CSV with members missing from new membership

    Thanks

    Hasan

    As always read the ful lhelp carefully and completely. It will provide the answers and examples for all of your questions.

    help compare-object -online

    Add the parameter "IncludeEqual" to your command.

    Also you don't need to use quotes all over the place.

    $test1=import-csv -path FilteredMailboxes.csv
$test2=import-csv -path ReportingUsers.csv

compare-object $test1 $test2 -Property mail -IncludeEqual | 
	Export-Csv test3.csv -NoTypeInformation

    Hi,

    Thanks for your question.

    You can try to use where-object to filter new members.

    Compare-Object $t1 $t2 -Property mail -IncludeEqual | Where-Object {$_.SideIndicator -eq "=>"}

    Best regards,

    Lee

    Just do it.
