Thank you Ben for your input and testing. And yes we still disagree if it's an error or not. But you have clearly understood my problem anyway (even when bending the meaning of words) so that is great!
Now back to the problem:
So our test's combined shows that deleted folders containing mails are indeed irreversibly deleted when in SmartCloud. AND the content of the folders are not deleted even if they are in a folder that the user have actively chosen to delete (not a normal behavior)! So to not mix up SmartCloud users with on-premises:
When IBM SmartCloud users delete a folder:
1. The user irreversibly loses the folder structure. Can't be restored.
2. The user THINKS the e-mails and the folders are gone. But the e-mails are actually still stored under all documents.
3. The mail db are now filled with what might be tens of thousands of unstructured e-mails that the user most likely wanted to delete.
3.1 If the user accidentally deleted the folders it's still more or less impossible to sort back into a identical folder structure.
And for on-premises server users:
1. The user loses the folder structure. It can however be restored from a domino server backup.
2. The user THINKS the e-mails are gone. But they are actually still there under all documents.
3. All documents are now filled with what might be thousands of unstructured e-mails. That potentially could be duplicated when restoring the folder structure (depending on type of restore).
- If this is not an error and the deletion of folders are truly "working as designed" then I would like to hear the motivation from the designer at IBM explaining the logic behind. ;-)
Thanks again!
