How to Change an Outlook Email Account from IMAP to POP3
Product
Microsoft Outlook
Device & OS
not provided
Scenario
Switching email protocol settings in Microsoft Outlook to download emails locally instead of syncing them directly with the mail server.
Observed behavior
Outlook does not provide a direct conversion tool or toggle to change an existing IMAP account into a POP3 account.
Before you start

Before making any changes to your account settings, export your current Outlook data (including emails, contacts, and custom rules) to a .pst file to prevent accidental data loss during the transition.

Solution 1Recommended

Re-add the Account with POP3 Settings and Transfer Data

Because Outlook cannot convert protocols directly, you must manually add the account using POP3 credentials, migrate your data, and then remove the old IMAP connection.

Microsoft Outlook locks the protocol type once an account is created. To switch from IMAP to POP3, the system requires a fresh account setup to establish the correct local data file structure.

It is highly recommended to keep the IMAP account active until you have verified that the new POP3 account successfully sends and receives messages.

1
Gather POP3 Server Settings

Check with your email provider or IT administrator to obtain the correct incoming (POP3) and outgoing (SMTP) server addresses, port numbers, and encryption methods.

2
Add a New Account in Outlook

Open Microsoft Outlook, click on the 'File' tab in the top-left corner, and select 'Add Account'.

3
Choose Manual Setup

Select 'Manual setup or additional server types' (or 'Advanced options' depending on your Outlook version), click 'Next', and choose 'POP or IMAP'.

4
Enter POP3 Credentials

Fill in your name, email address, and select 'POP3' from the Account Type dropdown menu. Enter the incoming and outgoing server details you gathered earlier.

5
Test the Configuration

Click 'Test Account Settings' to verify that Outlook can log onto the incoming mail server and send a test email successfully.

6
Transfer Data and Remove IMAP

Import any previously backed-up emails and rules into the new POP3 inbox. Once verified, go to 'File' > 'Account Settings', select your old IMAP account, and click 'Remove'.

Re-add the Account with POP3 Settings and Transfer Data
Leave a copy of messages on the server: If you want to access your emails on other devices (like a smartphone), ensure you check the box for 'Leave a copy of messages on the server' under the Advanced settings of your new POP3 account.

Frequently Asked Questions

Why can't I just change the incoming server settings from IMAP to POP3 in Outlook?

Outlook locks the protocol type once an account is created. To switch protocols, the system requires a fresh account setup to establish the correct local data file structure (.pst for POP3 versus .ost for IMAP).

Will I lose my emails when removing the IMAP account?

If you remove the IMAP account before backing up or waiting for POP3 to download your inbox, you might lose locally cached items or folder structures. Always export a .pst backup first. Emails will generally remain on your webmail server unless your new POP3 settings are configured to delete them immediately.

What are typical POP3 server settings?

Typical settings involve an incoming server address (such as pop.gmail.com), a port number (usually 995 for SSL encryption), and outgoing SMTP server details. You must check with your specific email service provider for exact credentials.

Can I have both IMAP and POP3 accounts active at the same time?

Yes, you can temporarily have both active in Outlook during the transition phase. However, it is not recommended for long-term use as it can cause duplicate emails and sync conflicts.
