Managing Storage

How Zoho Mail calculates storage

The allocated storage of a user is based on the subscription plan of their organization. In the case of a personal user, the storage will be based on Zoho Mail's allocation. The overall storage of your account is used to store all the data of your mailbox including POP and IMAP accounts, e-discovery, backup and archival, huge attachments, trash emails, and any other feature that may require storage space.

For example, consider the mock storage report below. Here the user has overall storage of 100 GB allocated. This storage can be used for any Zoho Mail feature that requires data to be stored. Let's say this user has  email retention enabled. The storage space needed to archive the retained emails will also be taken from the overall storage of the user.

Check your storage details

You can check the current usage of your mailbox, which includes the storage used by the Zoho account and all the POP accounts in Zoho Mail. The usage details will be available on the Mail Accounts page in your email settings Settings. You can view the storage details of your account from your User Profile section.

Mailbox storage

You can check the current usage of your mailbox, which includes the storage used by the Zoho account and all the POP accounts in Zoho Mail. The usage details will be available on the Mail Accounts page in your email settings Settings. You can view the storage details of your account from your User Profile section.

Steps to view your current Mailbox storage

1. Log in to https://www.zoho.com/mail
2. Click Settings  >> Mail Accounts.
3. The list of accounts will be in an LHS column. You can find the storage used by a particular account in the listing.

To view the storage details from your profile, click on your Avatar and scroll down.

Folder-wise storage

You can also view the folder-wise storage details by navigating to Settings > Mail > Folders. The storage used against each folder will be shown under the Size section.

From Admin Console: Accessible only by Admins and Super Admins

The Administrator of any organization can view the Storage details of the user accounts in that Organization from Admin Console. To access user's storage details:

1. Log in to Zoho Mail Admin Console.
2. Navigate to the Users section in the left pane. The users' personal information appears which is the Default View.
3. Click on the Change View icon (four horizontal bars) in the upper right corner and select Storage View to view the users' storage information. 

This section displays the Allotted and Used Storage of all the users in the Organization. You can also view a Storage report of the users in this section. Click the Summary button in the top pane to view your organization's plan and Add-on details, such as plan names, the total license count, and the number of used and available licenses. You can click on the Export option to export the Storage Details as a .csv file.

 Mailbox storage exceeded

The personal @zoho.com account users have allotted storage of 5GB. The business users have the allotted storage, based on the plan and the storage allotted to them by their administrators. 

When the mailbox exceeds the allotted storage, the incoming emails to the accounts are blocked and any POP accounts are temporarily disabled. You can either delete emails to create more space or purchase additional storage, to create free space in the account.

Additional storage

If you are an organization user, you can request your administrator to allocate more storage to your account. If you are a personal user, you can buy more storage from the Mail Accounts page in Settings. The Super Administrator can buy the storage units and allocate them to the users. 

You can literally have a bottomless mailbox with Zoho Mail. The add-on storage is available in units of 25 GB, 50 GB, 100 GB, and 200 GB sizes. In case you have an ever-growing mailbox and need more than 200GB of storage, you can contact support@zohomail.comwith your storage requirements, for us to get back to you with the relevant pricing.

Delete unwanted emails to create free space

Suppose you choose to delete older emails, instead of purchasing storage, you can proceed with the deletion of email using the Empty Folder option, available on right-clicking the folder name. Once you have deleted the unwanted emails or folders eating up your space, click Empty Trash, for the storage to be recalculated. Further, if you need to have a backup of emails in your Zoho account before deleting them, you may download it to a POP client. The configuration details for configuring your Zoho-based account over POP are available on this help page. The only option available to backup emails in the POP accounts added to Zoho Mail is the 'Export email' option.

If you notice that the storage does not change, even after you delete emails, check the 'Archived Emails' and remove them to create storage.

 Unblock the account:

Once you have deleted some emails to create some extra storage or purchased additional storage, you can resume working by unblocking yourself. You can unblock your account using this link https://mail.zoho.com/UnblockMe.

You need to clear the Captcha to unblock your account. Alternately administrators can also unblock the users in their organization. Refer here for instructions.
