If you use the Outlook client on a personally allocated Oxleas laptop you can use this tool to encrypt emails with attachments up to a total of 5Gb.
Emails sent with the Egress large file transfer tool are sent securely with or without specifying [secure] in the subject line.
Don't include personally identifiable information in the subject line when sending a secure email externally as the subject line is not encrypted.
You will be prompted to authenticate with Egress using your NHSmail credentials the first time the Outlook client opens after this add-in is installed.
You can tell this is installed when an Egress group is available in the new email ribbon.
Adding a date and time restriction is optional and not required to send an email encrypted.
Select Attach Large Files from the new email ribbon.
Files can be dragged and dropped into the large file transfer pane to the right.
Alternatively, files can be attached by clicking Select Files and using the file browser to select them.
Once a file is attached you will see it listed near the bottom of the large file transfer pane with the total size of all attachments. You can ignore the warning about recipients with an @nhs.net email account needing the Egress LFT Outlook add-in and if you are prompted to select a send method, select Upload to Egress Cloud.
While attachments are uploading you can monitor progress from the main Outlook window and clicking 1 message processing in the Egress group on the ribbon to show the Processing Packages window.
NHSmail have produced this guide: Egress large file transfer web form.
If a recipient does not have the Outlook add-in they will see an email with a link to access an encrypted email or download any attachments through the NHS Egress portal.
