I am currently assisting a client with an issue in UNIFYBroker, whereby a Google Group connector, is reporting a duplicate account error for some users when trying to added them to google groups. We can inspect the groups manually in google and these groups definitely do not contain these users. Being unable to find a root cause for the issue in Broker/MIM, the client raised a ticket with Google and received the following response:
Thank you for contacting Google Cloud Support. I understand that you are not being able to add an address to one of your Groups as you are getting a message that the address has already been to the Group.
I reviewed the information you provided on the chat and did the checks we do in this cases. The reason you are not able to add the external address is because the address you are trying to add is either an alias, a contact or a recovery address for a Google account. The system has the Google account already associated to the Group and since the system already knows the main account is already added it does not let you add it again. In this case you will need to contact the external user and ask for an alternate address they may have and check if that address is already on the Group. The other address is already receiving the messages sent to the Group.
Not being able to find a solutions around this within Broker and MIM I was hoping you may be able to take a look and see if you can spot anything we may be missing here.
This issue has quite a big of attention within the client environment as key people are missing out on important Covid-19 information. The current work around is listed in Google's response, however this often takes weeks to remediate.
Let me know if you need any further information.
