Hi @Samuel,
Thank you for reaching out and welcome to Microsoft.
The error message:
The system cannot find the file specified
It means that the database it is trying to run the attachability checks on is not found within that snapshot/database.
We need to heck the logs to find out which database it is failing on exactly. Could you please provide the detailed logs here to help us narrow down the issue?
Thanks for your understanding. Your time and cooperation are much valued by us. We are looking forward to hearing from you to assist further.
Best regards,
Lucy Chen
