Converting Distribution Group

Yes, you can convert this to a Universal Group without any issues. Once you have done that you will then be able to add other Groups to this group.

Will.

you can also do it from Exchange shell command if you want to change multipal .

Get-DistributionGroup | where { $_.Grouptype -Like "Global*" } | Set-Group -Universal

When I try to convert, I am getting an error: "A global group cannot have a universal group as a member"

So you already have Universal Groups listed within this Global Group?

What I think might have happened this that this was once a Universal Group, someone added other universal groups to this one and then changed it to a Global Group.

What I would do is remove all of the Universal Groups from this Global Group, change it to a Universal Group and then re-add the other groups that were their originally.

NO. The group members are users only.

Are you trying to preform this from EMC or from ADUC?

Will.

Tried both -- same result.

Is this group a member of any other groups?  If so, this group from their memberships, convert, then rejoin the groups.
If that is not the case, then go into Active Directory Users & Computers, first ensure you have Advanced Features checked under the View menu, then right click the distribution group, select properties, go to the security tab then advanced.  Check the box Include inheritable permissions from this objects parents and select OK.

Then retry the operation again.

Refer to the graph below "Nesting one Group within another with a different scope"

Exchange only support Universal distribution group.

Assuming you are only one domain
and you hit an error of  "A global group cannot have a universal group as a member"

From the error, it means you have nesting group
Rule i) Global group can only have global group as a member but not universal group
Rule ii) Universal group can have global group and universal group as a member

so imagine you have G1 has a member G2 and user A
G1 and G2 are global group
User A are user.
if you change G2 first, then G1 will failed the rule i) - hence you block your change on G2 and throw up the error
so You need to change G1 from global to universal

and imaging you got another nested relation of G0 has a member of G1 and User B
then you can't change G1 (as it fail rule i) so you need to change G0.


The nested group is killing you so you need to sit down and work out their nested relationship.

This works if I change the distribution group to Global and then add the target group to it. I can only add through AD Users and Computers -- EMC has this option disabled once the group is converted to global. Can someone explain this?
