Hi Neil,
I have done some tests using my test tenant but cannot reproduce the issue, my RBAC version is 0.1 (15.1.639.11). To identify if the issue is related to the RBAC version or any other factor, please firstly help us confirm the following
information:
- Try adding other roles to the "Organisation Management" role group, see if you get the same error message.
- Create a new global admin account(you don’t need to assign any license to this account), then use the account to log into EAC(Exchange Admin Center) and assign Address List role to this account.
- Connect to Exchange Online PowerShell, then:
Run the command below in the exchange online powershell to check if there is any error message:
*new-managementroleassignment -role "address lists" -user *****@contoso.com -delegating
If there isn’t an error message, then run the command below to assign the address list role to your admin account:
*new-rolegroup -name "address list management" -roles "address lists" -members *****@contoso.com
Note: replace ******@contoso.com with your admin account's email address.
If you receive any error message, please share its screenshot for analysis. As a tip, please mask your private information in the screenshot.
Meanwhile, if the issue is related to the RBAC version, we need to collect your tenant information to help to upgrade it. For privacy concern, I have sent you a private message to collect it. You can click the following link to access
the PM.
