I am receiving an error, MaxItemsExceeded, when I index data I added to an advanced ediscovery case. I added 10 custodians and their data both exchange and one drive. Instead of indexing all the data I indexed one custodian at time and am now receiving the error on one custodian. The others completed. How do I get around this error? I am assuming I am hitting a limit in advanced ediscovery. Can I separate email from onedrive data?
