When using O365 Admin portal to view all users with errors we get errors like the ones below:
1. Exchange: Multiple reference parameters "RawGrantSendOnBehalfTo" point to invalid values "e9449845-49c2-4714-a636-2f463796c670
2. Exchange: An unknown error has occurred. Refer to correlation ID: 9b4c1c2f-4ed5-4331-9447-c34e1eee8568How do you go about troubleshooting these vague error messages. We get these errors for about 20 users and I do not see anything unusual about them.Thanks
