Test offline copies before relying on them

A document visible in an app is not always a complete local copy you can use offline.

1. Choose only the files you need and save permitted local copies in a format your device can open.
2. Use clear names and keep related attachments together. Check that pages, images and any required reference numbers are present.
3. Temporarily disconnect from the network when it will not interrupt other work. Close and reopen the viewer, then open each saved file.
4. Restore the connection afterward and note when copies should be refreshed. Remove outdated duplicates so the correct version is easy to identify.

A saved page may not preserve interactive forms or live updates. Protect sensitive documents according to your organization's rules and keep an alternative for essential access.
