You don't have sufficient permissions

Question

Hi

I am using exchange 2016 hybrid environment. i have an onprem mail enabled security group. i am unable to add members or add owner to this mail enabled security group, i am getting the below error

You don't have sufficient permissions. This operation can only be performed by a manager of the group. Are the below syntaxes correct. i want to add owner, add users and modify delivery management.

Import-CSV C:\list.csv | ForEach {Add-DistributionGroupMember -Identity group1@contoso.com -Member $_.users -BypassSecurityGroupManagerCheck}

Set-DistributionGroup group1@contoso.com -ManagedBy @{Add="user2@contoso.com"} -BypassSecurityGroupManagerCheck

Set-distributiongroup "mailenabledsecuritygroup" -AcceptMessagesOnlyFrom @{Add="user3@contoso.com","user4@contoso.com"} -BypassSecurityGroupManagerCheck

@Rising Flight

If you are not the owner of this group, you could use the "-BypassSecurityGroupManagerCheck" to modify this group.

Do you get any error message when running this script?
