Right Click on a folder and select Archive options. You can archive the messages in a folder. The selected emails will be unarchived and will be available for further IMAP access. You need to select the same folder, to unarchive the emails to the same folder.

In the listing, select 'Move To' and select the folder to which you want to unarchive the emails.

Select the messages you want to Unarchive.

You can use the View archived option to view all the archived emails in the folder. The emails will be Archived but will remain in the same folders. The archived emails will not be synced in the IMAP clients. The Archive action does not reduce the used storage of your account, as the emails still remain in your account. This removes the emails from the listing, but the emails remain in the folder as archived emails. You can select the emails you want to Archive and click the Archive option.

When you use 'Empty folder', the archived messages in the folder are not removed.

(Trash emails are deleted permanently if they're not recovered within 30 days)

The emails deleted from Archive are not permanently deleted and can be recovered from Trash.The 'Unread' count in a folder, does not include the unread emails you have archived.

This makes it easier for reference and retrieval. When you Archive an email, the email remains in the same folder but gets removed from the listing of emails. The Archive feature in Zoho Mail helps you to retain the older emails in your inbox but without clutter.
