When you log into Jatheon Cloud, the search page will be the first thing you'll see. You can select the Import page under the Settings menu.
In order to use the secure upload URL, you'll need to contact Jatheon Support, who will provide you with your login credentials. Once you get them, you'll able to access your personal secure upload space and upload your PST, EML or zipped EML files by clicking the provided link.
Once you click the upload button, you can simply drag and drop the files that you want to upload.
Wait for the upload to finish and return to Jatheon Cloud. Reload the page if the uploaded file doesn't show up automatically and start the ingestion.
After the ingestion process is done, the status will change from "processing" to "completed".
