Hi,
I have come across a strange issue in CRM. Somehow a user is in two different business' unit's default teams at the same time. If I try to remove the one that is incorrect I get an error message saying I cannot remove the default business unit's team. Normally CRM would prevent this scenario ever happening, but somehow it has happened.
Any tips or advice?
Here is a screenshot from the user record showing the issue:

UPDATE**
Thank you all again for taking the time to answer.
I tried to remove the user form the Customer Service team but it would not allow me to do it and came up with an error.
I also tried setting the BU of the user to the Customer Service but it came up with a duplicate key issue (probably because the user is in the default team for the Customer Service BU already):
After looking through Audit history I can see where the Customer Service team association was made, but the BU was not changed to Customer Service. Somehow the internal CRM checks to prevent this happening weren't running? Not really sure as I didn't run the script my self:
Now to try and find a solution...hopefully a script will allow the Customer Service team to be removed, otherwise a record might need to be removed from the DB itself.
