Health Care Component accounts
Due to privacy concerns surrounding HIPAA compliance, this feature is not available for accounts that fall under the restricted Health Care Components that work with protected data.
At this time Gmail Offline Mode is only available in the Chrome browser. This feature will not work with Firefox, Internet Explorer or Safari web-browsers.
Clearing Browser Cache/Cookies
When your browser cache and/or cookies are deleted, your offline messages will also be deleted. Gmail will re-download your messages per your GMail offline settings once you sign back into your Google Apps account. This can take several hours depending on your internet connection and settings.
