### Senders

Senders must use a supported Gmail or Outlook environment and install the correct SecureMail component.

### Recipients

Recipients do not need to use Gmail or Outlook. They can access secure links through supported web browsers.

### Mobile Recipients

Recipients can access secure links on mobile web browsers, even though sending from mobile Gmail apps is not supported.

## Troubleshooting and Compatibility Checks

If SecureMail does not appear or does not function as expected, check the following first.

1

### Confirm your email platform

For Gmail, use Chrome on a supported desktop OS. For Outlook, confirm that you are using Microsoft 365, Office 365, Exchange 2016, or Exchange 2019.

2

### Check browser or client compatibility

SecureMail for Gmail requires the Chrome browser. Non-standard email clients and older Exchange versions may not be compatible with the Outlook add-in.

3

### Restart the browser or Outlook

After installation, restart Chrome or Outlook if the SecureMail control does not appear immediately.

4

### Contact support if needed

If your environment appears to be supported but SecureMail still does not work, contact 689Cloud support with your OS, browser/client version, and email platform details.
