Hi @Susan Dodds ,
According to my research and check. I didn’t see any audit log in database files and transport log files.
In order to better solve this issue, I want to confirm with you the following points:
- What do you mean by "Exchange database audit log?
- Is it generated by your backup tool?
- What is the backup tool you are using?
About the original database name.
1.According to my test. I changed the database name in EAC, but dataset name not be changed in C:\install path\database. Could you see it?
2.How long have you changed? The admin audit log will retention 90 days by default. If you changed during this period, you could run the following command to see the changes made to the database name.
Search-AdminAuditLog -StartDate <> -EndDate <> -Cmdlets Set-Mailboxdatabase -Parameters Name
