Hi
We recently got a storage exceeding mail, now I've been deleting and bulk deleting thousands of records but it appears to have near to no influence on the capacity.
For example I've cleaned records (systemjobs) that should lower the AsyncOperation(Base) tables. As these tables were high too.
The AsyncOperationBase under Data has lowered by half but the AsyncOperation under File remains as high as it was. The biggest storage issue is on the Files section of our environment.

Another table that is capturing a lot of data is the Attachments section, I've already deleted all attached emails with large attachments but this also has very little impact.
What else is there being stored as 'attachment'? We don't use notes with an attachment.
I'd seen the earler mentioned SystemJobs on the AsyncOperations now being present under File storage but it didn't seem to affect it whatsoever.
I've ran through all kinds of support topics and microsoft documentation on the types of records stored in the different sections, but none seemed to help me get done what I needed. So hopefully there is anyone else that can shine a light.
