How to Synchronize Outlook Email Across Multiple Devices
Question details
The user wants to know how to keep their Outlook emails, folders, read status, and sent items synchronized across all their computers and mobile devices.

- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Setting up an email account on multiple devices and needing all inbox changes to reflect universally in real time.
- Observed behavior
- To achieve full synchronization of emails and folders, the account must be configured correctly, as standard POP setups only download isolated copies of messages.
Verify your email provider's supported protocols. You will need your account credentials and incoming/outgoing server settings if you are setting up an IMAP connection.
Use a Microsoft 365 or Exchange Account
This is the best method for complete synchronization, ensuring emails, folders, calendars, and contacts are seamlessly updated across all devices.
Microsoft 365 and Exchange Server accounts offer native, comprehensive synchronization. Actions taken on one device (like reading, deleting, or moving an email) are immediately mirrored on the server and all other connected devices.
Launch Microsoft Outlook. Click on 'File' in the top left corner, then select 'Add Account' under the Info tab.
Type your Microsoft 365 or Exchange email address into the prompt and click 'Connect'.
Enter your password and approve any two-factor authentication prompts if required. Outlook will automatically configure the Exchange settings.
Install Outlook on your mobile device or secondary computer and add the account using the exact same steps.

Configure an IMAP Account
Use this solution if your email provider does not support Exchange. IMAP successfully syncs emails and custom folders across devices.
Modify POP Account Settings
If you absolutely must use a POP account, adjust the settings to prevent emails from being deleted from the server upon download.

Frequently Asked Questions
Why are my sent emails not showing up on my phone?
This happens if your account is configured as a POP account, which only downloads inbox emails locally. To view sent items across all devices, you need to configure your email using an IMAP or Exchange account.
Does IMAP sync my calendars and contacts?
No, the IMAP protocol only synchronizes email messages and folders. If you need your calendars and contacts to sync across multiple devices automatically, you must use a Microsoft Exchange or Microsoft 365 account.
How can I change my Outlook account from POP to IMAP?
You cannot directly switch an existing account from POP to IMAP in Outlook. You must add the email account again using the 'Add Account' process and selecting IMAP. Once the new IMAP account syncs, you can manually drag emails from your old POP folders to the new IMAP folders before removing the old POP account.
