We've encountered an issue with files that are encrypted using a Pureview sensitivity label. After performing a restore, these files become corrupt and cannot be opened. This problem specifically affects files that were backed up using version 8.1.1.159.
Interestingly, we found that files backed up with version 7 can be restored using version 8 without any issues, and they open perfectly fine. It's worth mentioning that we had a similar experience with Veeam Data Cloud, which led us to continue using Veeam for M365. Unfortunately, we are now having the same problem once again.
Could this be a limitation or change in the new APIs or permissions that version 8 utilizes?
Thanks
