Security settings

You can decide if you want to retain the offline data stored in your browser when you log out. You can choose from one of the following options:

Security settings for offline email mode

  • Retain previous 7 days offline data in this browser - This will ensure faster sync the next time you log in.

  • Remove all offline data from this browser - Since the offline data is cleared, the next time you log in, the sync might be slower.


This section displays the storage information of your browser. It includes the total storage and the storage that has been used by the offline data. 

How does it work?

By enabling the Offline mode, you can sync the emails of your choice when you are connected to the internet. These emails are stored in the browser where you have enabled Offline. Create a bookmark as mentioned in the settings, for later use. Once the syncing is done, you will be able to access your emails offline. When you are disconnected, use the bookmark to access Zoho Mail or navigate to mail.zoho.com/zm/  to view the emails that were synced. 

Points to remember

  • Do not enable Zoho Mail Offline in shared or public computers.
  • Enabling Offline is specific to the browser hence Offline access will only be available in the browser where Offline is enabled. 
  • You can access Zoho Mail Offline in only one tab in the browser. 
  • In the case of conversation threads, the emails in the mentioned date range will be stored. In addition to these emails, the previous 200 emails in the conversation are also stored offline. 
  • If you send an email with Outbox delay when in Offline mode, the delay will be considered from the time when you are back online. For example, if the outbox delay is set as 30 seconds, it will be timed from the instant you are online.
