As part of our recent security upgrades, we've changed the way FLK it over stores and shares large PDF files, to keep your documents and your clients' information secure.

Previously, when the PDFs attached to a document added up to more than 8MB, we hosted the files separately and included a link for the recipient to open them, rather than attaching them to the email. This made sure the email was delivered and not rejected for being too large.

This applied both to a single large PDF and to several PDFs that together exceeded 8MB.

From 4 October 2026, these files are stored with additional security controls in place.

Large PDFs were sent as a link from:

PDFs under 8MB in total were attached to the email as normal and aren't affected.

Links to these PDFs created before 4 October 2026 have now expired. If a recipient didn't open or download the PDFs before then, they can no longer access them.

If anyone clicks an old link, they'll see a message explaining that the link has expired and asking them to contact you for a copy.

For most users, no. This is simply an update to how the platform works.

However, if you've recently sent an important notice where the supporting documents form part of a legislative requirement (for example, a termination notice with attachments), we recommend reviewing it.

Option 1: Check your CC'd copy

You're usually CC'd on these emails. Open your copy of the original email to see how the PDFs were delivered: as attachments, or as a link.

Option 2: Check the file size on your dashboard

If the attachments add up to more than 8MB, they were sent as a link.

You can either:

Everything will work as it does today, and there's nothing you or your clients need to change.
