Hey Mark,

The archived data folder contains JSON files, which are mainly calendar and configuration files. To retrieve emails, follow these steps: Take the emails and move them to a new folder. Please note that GRP files are created by date. Each file contains email for that day. Place this new folder at the root level alongside the inbox, junk, and spam folders. Then, log in as an admin, use the "attach folder" option, and enter the name of the folder you placed in the user's root level mail folder. This should cause a new folder to appear in webmail with the lost emails.

Since you already have the emails in the inbox folder, you could also try using the "rebuild folder" option. However, be aware that this may result in the loss of categories or tags.

Hope this helps.

Thanks,
