Hi,
Goal is to have standard naming convention
For the currently existing distribution lists, you may consider renaming their display names using powershell script:
- Prepare a CSV file which includes both the old and new display names of the distribution lists, for example:
- Bulk rename the display names using the powershell command below: $Groups = Import-CSV Sample.csv
ForEach($Group in $groups) {Set-DistributionGroup -Identity $Group.OldName -DisplayName $Group.Newname}
After that, you can create a distribution group naming policy to manage the names of new distribution groups created by users or by administrators via EMS (naming policy isn't applied to distribution group created using EAC). For more details, see Create a distribution group naming policy.
Regarding your concern about adding the DLs into the other DLs, based on my test, this is by default supported.
