Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query
It sounds like you are having trouble downloading files from Microsoft 365 Compliance using the eDiscovery tool. This kind of issue can occur due to several reasons, such as corrupted files or incorrect permissions. You may want to try running the command Export-ComplianceSearch with the -BypassErrors parameter to see if that helps. Additionally, you may want to check the permissions on the files that are being exported to make sure they are set correctly. Finally, you may want to try running the command Repair-ComplianceSearchIndex to try to fix any indexing-related issues.
