Hello!
In brief, I created an advanced eDiscovery case and initiated a bulk import of 5 custodians via Microsoft 365 Compliance Center. While the bulk import template sets Exchange and OneDrive to TRUE, and after the bulk import is complete, I confirm the mailbox added for all 5 custodians. However, it does not add the OneDrive directory for the custodian for 4 out of 5 custodians. When I attempt to manually add the OneDrive directory for one of the 4 custodians, I am unable to click on the "Edit" link in the OneDrive row. Also, I confirmed there is an active OneDrive directory available for each custodian.
Any reason why the OneDrive directory is unavailable, although there is an active OneDrive directory for the custodian?
