What happens when your phone is offline

How mail drafts, chat messages, uploads and documents behave without a connection, and how to retry.

Updated Nov 12, 2026

Phones lose signal. The app is built so you do not lose your work, though some things need a connection.

Mail

If a message cannot be sent, you see Couldn't send. Your message is saved in Drafts. Open Drafts, check it and send again when you are back online. You can also save a Draft deliberately, use Send later, or Send now.

Chat

A message that did not go out says Not sent. Tap to retry. Tap it once you have a connection.

Uploads

Files you add to Drive go into an upload queue: Uploading N of M files, or Waiting for a connection… when there is no signal. Failed uploads show N uploads failed with Retry. Use Clear to remove finished items or Cancel uploads to stop the queue.

Documents, sheets and slides

A document you have opened on this device before shows its last saved version when you are offline: Offline – showing last saved. One you never opened there says you are offline and it has not been opened on this device yet. Comments need a connection. Live editing reconnects on its own: the status moves from Reconnecting… to Live.

Good to know

  • Removing an account from the phone deletes its cached mail, drafts and settings on that device.
  • Large PDF jobs run in the background, and you get a notification when they finish.

Tips

  • Before a flight, open the documents you need so they are on the phone.
  • If many uploads failed, switch to a stable connection and use Retry.
