Invalid / Duplicate Email Error Message when attempting to share dataset
This is now resolved. My guess is that a patch or update may have been pushed down as we did not change anything on our end.
Although that's an old post, I will leave it here if someone else still encounters this issue.
I encountered the same problem and at least one reason for it seems to be common prefix names for AAD security groups. For instance if you're trying to add a group called CLD-EU-PBI-US and you have other groups called CLD-EU-PBI-US-West and/or CLD-EU-PBI-US-East, you might be getting that error if you're simply copy pasting the CLD-EU-PBI-US group name. That seems to be a Microsoft bug as it tries to map your input string to AAD groups and there is more than one satisfying the query (that's my suspcicion, at least). To solve this, try to remove the last character and then select the group from the drop down or type in the group name by hand and select the correct value when it shows in the field drop down.
