mail enabled security group

Question

Hi All
I am using exchange 2010 hybrid environment, I have a csv file in the below format. I want to add the below users to mail enabled security group, will the below syntax work in exchange online and exchange 2010
users
user1@Company portal .com
user2@Company portal .com

Import-csv C:\userlist.csv | ForEach {Add-DistributionGroupMember -Identity group@Company portal .com -Member $_.users}

experts help me with the syntax to create a mail enabled security group from PowerShell in exchange 2010 and exchange online.

Answer 1

To mail-enable an existing on-prem security group ( and this will sync to 365/ Exchange Online with AADConnect)

Enable-DistributionGroup -Identity ******@contoso.com  

Then to add the members:

Import-csv C:\userlist.csv | % {Add-DistributionGroupMember -Identity ******@contoso.com -Member $_.users -BypassSecurityGroupManagerCheck}  

The -BypassSecurityGroupManagerCheck is needed if you don't own the group, so it should typically always be used.

Answer 2

Your syntax should be worked.
Please refer official document for further details.

Answer 3

Hi @Glenn Maxwell , agree with the replies above, first make sure you have on-premises security groups mail-enabled so that they will able to be synced to Exchange Online.

Then run the command you provided above, they should work properly.
