We have a large exchange environment and always need to run exchange commands -results unlimited Which I can do with your
DistributionGroupMigration PowerShell module can you modifiy it. I love your tools but can't use it if I can't have multi DL run in the command we have 1700 DL we need to migrate not all at once only by location as that location email is migrated to O365. Still allot of DL. below is

I'm not sure how you run Initialize-OnPremDSTGroupToCloud. Do you run as the example?

$DSTs = Get-DistributionGroup -Filter {IsDirSynced -eq $true} -Resultsize Unlimited
$DSTs.PrimarySmtpAddress | Initialize-OnPremDSTGroupToCloud -ExchangeServer exchprod01.contoso.com -Force

Philip Thanks for your reply. No I did not. I am only trying to move a test groups and when ready to only move the DL’s that are part of the locations we are migrating users to O365. We have over 1700 DL’s 25,000 user mailboxes. This is the script I was trying to run with only 5 dl in $GroupDL $GroupDL = import-csv D:\import\testgroupDL1.csv Foreach ($GroupDL in $GroupDL) { # https://github.com/PhilipHaglund/DistributionGroupMigration/blob/master/docs/en-US/DistributionGroupMigration.md Initialize-OnPremDSTGroupToCloud -Group $GroupDL.PrimarySmtpAddress -ExchangeServer <exchange server name> -Prefix 'PreMig-' -LogPath "D:\dl" That is when I get the error There are more results available than are currently displayed. To view them, increase the value for the ResultSize parameter. It is probably a simple script but I am not a great script guy more a hacker of other scripts like most admins. And have to be careful I do screwup the DL’s I tried adding -Resultsize Unlimited to Initialize-OnPremDSTGroupToCloud that did not work. If you could point me in the right direction that would be great.

Have you verified the content in the CSV is correct when assigning to the $GroupDL variable?
You are using

Foreach ($GroupDL in $GroupDL)
{

Which will work one time, but I suspect that the $GroupDL with the property PrimarySMTPAddress is causing the error.

If you run this cmdlet, will it produce 5 email addresses?

foreach ($Group in ($GroupDL | Select-Object -First 5))
{
    $Group.PrimarySMTPAddress
}

You can open the Initialize-OnPremDSTGroupToCloud.ps1 file and try to modify the row here to include -ResultSize Unlimited. https://github.com/PhilipHaglund/DistributionGroupMigration/blob/master/source/Public/Initialize-OnPremDSTGroupToCloud.ps1#L278

$Members = Get-EXCHDistributionGroupMember -Identity $ExchGroup.Identity -ErrorAction SilentlyContinue -ResultSize Unlimited
