If you want to access your Rediffmail account directly in Microsoft Outlook, the setup is simple once you use the correct server settings. I’ve configured it myself, and in this guide, I’ll show you how to configure Rediffmail in Outlook quickly and without errors.

Without wasting any time, let’s start our discussion with why this is required.

Why Sync Rediffmail with Outlook

Before jumping into the setup, here’s why I recommend this configuration:

I can access all emails in one place
Outlook provides better email organization tools
I get offline access to my emails
Advanced search and filtering save me time

Prerequisites Before You Start

Make sure you have the following ready:

Active Rediffmail account
Installed Outlook (2016, 2019, 2021, or Microsoft 365)
Stable internet connection
Correct IMAP/POP and SMTP settings

Rediffmail Server Settings

Always double-check these settings before configuration:

Incoming Mail Server (IMAP):

Server: imap.rediffmail.com

Port: 993

Encryption: SSL

Outgoing Mail Server (SMTP):

Server: smtp.rediffmail.com

Port: 587

Encryption: TLS

Note: Rediffmail does not always support POP3 reliably, so I recommend using IMAP for better synchronisation.

How to Configure Rediffmail in Outlook

Here’s exactly how I set it up:

Step 1. Open Outlook

Launch Microsoft Outlook
Go to File > Add Account

Step 2. Choose Manual Setup

Select Manual setup or additional server types
Click Next

Step 3. Select Account Type

Choose IMAP
Click Next

Step 4. Enter User Information

Fill in the details:

Your Name
Email Address (your Rediffmail ID)

Step 5. Configure Server Settings

Under Server Information:

Account Type: IMAP
Incoming Mail Server: imap.rediffmail.com
Outgoing Mail Server: smtp.rediffmail.com

Under Login Information:

Username: Your full email address
Password: Your Rediffmail password

Step 6. More Settings

Click More Settings > Outgoing Server tab

Enable My outgoing server (SMTP) requires authentication
Select Use same settings as incoming mail server

Now go to the Advanced tab:

IMAP Port: 993 (SSL)
SMTP Port: 587 (TLS)

Step 7: Test and Finish

Click Next
Outlook will test the account settings
Once successful, click Finish

IMAP vs POP3

IMAP > Best for syncing across devices
POP3 > Only downloads emails locally

Always go with IMAP for flexibility.

How to Make This Migration Smooth?

Manual methods like configuring Rediffmail in Microsoft Outlook using IMAP, I quickly realised they come with several limitations. The biggest issue I faced was that IMAP only syncs emails; it doesn’t create a true local backup. So, if an email gets deleted from the server or the account faces any issues, there’s a real risk of losing important data. Additionally, syncing large mailboxes can be slow, and Outlook performance may degrade over time. I also noticed that managing and exporting emails in bulk isn’t straightforward with manual methods.

That’s where the FreeViewer IMAP Backup Tool becomes a much better choice in my experience. Instead of just syncing, it allows me to create a complete and secure backup of all my Rediffmail emails directly from the IMAP server. I can save emails in multiple formats like PST, EML, or MBOX, which gives me flexibility for future use or migration.
