POP Account Settings

Accessing external accounts via POP

If you have multiple accounts with other providers, you can check them in your Zoho Mail account, by setting up each of those accounts via POP in Zoho Mail. In this case, Zoho Mail acts like a POP client and retrieves the emails provided for retrieval by POP Clients. You can customize some POP behavior in Zoho Mail, however, the execution of the behavior highly depends on the POP server configured by you.

POP Retrieval Settings:

You can configure the retrieval settings for the POP Accounts. Based on the Time Interval you have set, Zoho Mail connects to your server and retrieves emails once in every x minutes. The Time interval is the gap between two subsequent retrievals from your POP Server. The maximum number of emails is the optimum number of emails that can be retrieved in a cycle. When you configure the account in Zoho for the first time, there will be a lot of emails in the POP server, hence it might take 3 to 5 days to retrieve the emails from your server to Zoho.

  1. Login to Zoho Mail
  2. Go to Settings 
  3. Navigate to Mail Accounts >> Configure POP Fetch.
    POP settings
  4. Select the Time Interval from the drop down. The optimum value is '5' minutes.
  5. Specify the maximum number of emails that can be retrieved in a single cycle. The number can be between 20 and 200. The optimum value is 100 or 150

Authentication Failure for POP Accounts:

The 'Authentication Failure' error occurs when your POP server does not accept the credentials that you have provided in Zoho Mail. This error may occur when you have 'Changed your password with the Email Server' or 'your password has expired in your server due to password policies'. 

You need to update your password for the 'Incoming Server' and 'Outgoing Server' to send and receive emails without any issues.

Account Sequence

When you have multiple mail accounts, you can set the sequence or the order in which you want the POP accounts to be checked for mails. By default, the POP accounts are set in the order in which they are added. The same order appears in the POP accounts page by default. To change the order of POP accounts to your preference you can drag and drop the accounts to the required Order or number the accounts to reflect the required sequence.

Default Mail Account

When you have multiple POP accounts configured, in addition to your Zoho account, you can choose the default account based on your preference. The account which you choose as 'Default Account' will be the account that will be displayed first when you log in to the Zoho Mail. To choose any account as Default, click on the 'Default' radio button across the account.
