by

Managing multiple inboxes becomes easier when you learn how to merge two emails in outlook. This process lets you view all messages from two accounts in one place, saving time and reducing clutter. Whether you have a work and personal account, or just want to simplify your digital life, merging emails in Outlook is a practical skill.

Outlook offers several ways to combine accounts. You can add a second email to your existing profile, forward messages from one account to another, or set up a unified inbox. Each method has its own benefits, and we’ll cover them all step-by-step. By the end of this guide, you’ll be able to consolidate your emails without hassle.

How To Merge Two Emails In Outlook

This section explains the core method for merging two email accounts into one Outlook profile. The process works for Outlook 2016, 2019, 2021, and Microsoft 365 versions. You’ll need your second email address and its password ready.

Adding A Second Email Account To Your Outlook Profile

This is the most straightforward way to merge emails. Outlook will automatically sync both accounts, showing all messages in the same navigation pane. Follow these steps:

  1. Open Outlook on your computer.
  2. Go to File in the top-left corner.
  3. Click Add Account under the Account Information section.
  4. Enter your second email address and click Connect.
  5. Enter the password for that account and click Connect again.
  6. Wait for Outlook to configure the account automatically. This may take a minute.
  7. Once done, click Finish.

Your second email will now appear in the folder pane on the left. You can expand it to see its Inbox, Sent Items, and other folders. All new emails from both accounts will arrive in their respective folders, but you can view them all from one window.

Setting Up A Unified Inbox Using Folders

If you want to see all emails in one single folder, you can create a search folder. This is a virtual folder that shows messages from multiple accounts based on criteria you set. Here’s how:

  1. In Outlook, go to the Folder tab in the ribbon.
  2. Click New Search Folder.
  3. Scroll down and select Mail from specific people or Mail sent to public groups—but for merging all mail, choose Mail from all accounts if available. If not, use a custom approach.
  4. Alternatively, create a custom search folder: Click New Search Folder, then scroll to the bottom and select Create a custom Search Folder.
  5. Click Choose and name it “All Mail.”
  6. Under Criteria, set no filters to include all messages.
  7. Select Browse and check both email accounts’ Inbox folders.
  8. Click OK twice to save.

This search folder will display all emails from both accounts in one list. It updates automatically as new messages arrive. Note that it doesn’t move the actual emails—it just shows them together.

Forwarding Emails From One Account To Another

Another simple method is to set up email forwarding from your second account to your primary Outlook account. This way, all messages land in one inbox. The steps vary depending on your email provider, but here’s a general guide:

  • For Gmail: Go to Settings > See all settings > Forwarding and POP/IMAP. Click Add a forwarding address, enter your primary Outlook email, and verify it. Then select Forward a copy of incoming mail.
  • For Yahoo: Go to Settings > More Settings > Mailboxes > Forwarding. Enter your Outlook address and enable forwarding.
  • For iCloud: Go to iCloud.com > Mail > Settings (gear icon) > Rules > Add a Rule. Set it to forward all messages to your Outlook address.
  • For other providers: Look for “Forwarding” or “Mail forwarding” in your account settings. Enter your Outlook email and save.

Once forwarding is set, emails from your second account will arrive in your primary Outlook inbox. You can still reply using the original account if you configure the “From” address in Outlook. To do this, go to File > Account Settings > Account Settings, select your primary account, and click Change. Under Send from this address, add your second email as an alias.

Configuring IMAP And POP Settings For Merging

For more control over how emails are merged, you can manually configure IMAP or POP settings. IMAP keeps emails on the server and syncs across devices, while POP downloads them to your computer. Here’s what you need to know:

Using IMAP For Real-Time Sync

IMAP is ideal for merging because it keeps all folders and messages synchronized. When you add an IMAP account to Outlook, you’ll see its folders alongside your primary account. To set it up:

  1. Go to File > Add Account.
  2. Choose Manual setup or additional server types and click Next.
  3. Select POP or IMAP and click Next.
  4. Enter your name, email address, and account type as IMAP.
  5. Enter the incoming mail server (e.g., imap.gmail.com) and outgoing server (e.g., smtp.gmail.com).
  6. Enter your full email address and password.
  7. Click More Settings > Outgoing Server tab, and check My outgoing server (SMTP) requires authentication.
  8. Go to the Advanced tab and set the IMAP port to 993 (SSL) and SMTP port to 587 (TLS).
  9. Click OK and then Next. Outlook will test the connection and add the account.

Once added, you can drag emails between folders from different accounts if needed. However, dragging moves the message from one server to another, which may cause duplicates. It’s better to use search folders or forwarding for a cleaner merge.

Using POP For Downloading Emails

POP downloads emails to your computer and usually deletes them from the server. This can be useful if you want to archive emails from a secondary account. But it’s less ideal for merging because changes won’t sync across devices. To set up POP:

  1. Follow the same steps as IMAP, but select POP3 as the account type.
  2. Enter the POP server (e.g., pop.gmail.com) and port 995 (SSL).
  3. In More Settings > Advanced, check Leave a copy of messages on the server if you want to keep them online.
  4. Complete the setup.

POP will download all existing emails from the second account into a new folder in Outlook. New emails will also be downloaded, but they won’t appear on other devices. This method works best for a one-time merge or for backup purposes.

Using Outlook Rules To Organize Merged Emails

After merging two emails in Outlook, you might want to organize incoming messages automatically. Rules can move, flag, or forward emails based on sender, subject, or other criteria. Here’s how to create a rule:

  1. Go to File > Manage Rules & Alerts.
  2. Click New Rule.
  3. Choose a template, like Move messages from someone to a folder.
  4. Under Step 1: Select conditions, choose criteria like “from a specific account” or “with specific words in the subject.”
  5. Under Step 2: Edit the rule description, click the underlined links to set values (e.g., select the account or folder).
  6. Click Next and set actions, such as moving to a folder or marking as read.
  7. Finish the wizard and enable the rule.

For example, you can create a rule that moves all emails from your work account to a “Work” folder, keeping your personal inbox clean. This works well when both accounts are in the same Outlook profile.

Merging Emails On Outlook For Mac

The process for merging emails in Outlook for Mac is similar but has slight differences. Here’s a quick guide:

  1. Open Outlook for Mac.
  2. Go to Tools > Accounts.
  3. Click the + sign and select New Account.
  4. Enter your second email address and password.
  5. Outlook will configure the account automatically. If not, enter the server settings manually.
  6. Once added, both accounts appear in the sidebar.

To view all emails together, use the All Accounts view. Click the Inbox folder at the top of the sidebar—it shows messages from all accounts combined. You can also create smart folders to filter emails by account.

Merging Emails On Outlook Web App (OWA)

If you use Outlook on the web, you can still merge emails by adding another account. Here’s how:

  1. Sign in to Outlook.com or your work’s OWA.
  2. Click the Settings gear icon (top right) and select View all Outlook settings.
  3. Go to Mail > Sync email.
  4. Click Other email accounts and then Add an account.
  5. Enter your second email address and password.
  6. Follow the prompts to complete setup.

The second account will appear in the left pane under “Connected accounts.” You can click it to view its inbox separately. OWA doesn’t offer a unified inbox view by default, but you can use the Focused Inbox feature to see important emails from both accounts together.

Common Issues When Merging Emails And How To Fix Them

Sometimes merging emails in Outlook doesn’t go smoothly. Here are frequent problems and solutions:

  • Account not connecting: Check your internet connection and ensure your password is correct. If using two-factor authentication, generate an app password from your email provider.
  • Duplicate emails: This happens when you forward emails and also have both accounts added. Disable forwarding or remove the duplicate account.
  • Folders not showing: IMAP accounts may take time to sync. Click Send/Receive All Folders to force a sync.
  • Emails not sending from the correct account: When replying, Outlook may use the wrong “From” address. Check the account settings and set the default send account.
  • Search not finding emails from both accounts: Search folders only include indexed items. Rebuild the search index by going to File > Options > Search > Indexing Options.

Benefits Of Merging Two Emails In Outlook

Consolidating your emails offers several advantages:

  • Time savings: You check one inbox instead of multiple.
  • Reduced stress: No more switching between accounts.
  • Better organization: Use rules and folders to sort messages.
  • Improved productivity: Focus on all emails in one place.
  • Simplified backup: Archive all emails from one profile.

These benefits make the effort of merging worthwhile, especially if you manage multiple roles or projects.
