What Can You Search Inside MSG Files?

An MSG file stores much more than just the email body. And this is completely dependent on the search method or software being used.  You can search various email properties to quickly locate your specific messages.

Search by Subject

If you remember part of the email subject then you can search this by using keywords from the subject line. You can check below the example:

  • Project Update
  • Invoice #4587
  • Meeting Agenda

This is one of the fastest ways where you can easily locate your specific email among hundreds of MSG files.

Search by Sender

When you are looking for emails from a particular person or department then searching by sender email address or display name can remarkably narrow down results. Check below example:

Search by Recipient

Users can search their emails that are sent to a specific individual, group or department. This is especially very useful during audits, compliance reviews and internal investigations.

Search by Date or Date Range

There are a number of users who need to find emails exchanged during a specific period. You can also search by the following manner:

  • Specific date
  • Month
  • Year
  • And custom date range

You can check below example:

  • Emails received in January 2025
  • Messages sent between March 1 and March 31
  • And Communications from the last quarter

Search Email Body Content

One of the most common requirements for the users is to search the content of emails contained within MSG files using the specific words, phrases or any reference numbers.

Find Example Searches Below:

  • Purchase of Order
  • Renewal of Contract
  • Approval for Budget
  • And Employee ID

This will help you quickly find all your important conversations without the need for opening every MSG file manually.

Find Keywords in MSG Files

Keyword searching allows you to locate your emails that contain specific terms across large MSG collections.

Example Keywords:

  • Confidential
  • Payment Pending
  • Project Alpha
  • Tax Document

This method is widely used during legal discovery, compliance audits and for business investigations.

Search by Attachment Name

If you remember the filename of the attachment but not the email itself then searching for the attachment’s name can help you identify the correct MSG file. You can check example below:

  • Invoice.pdf
  • Contract.docx
  • Budget.xlsx

Search MSG Attachments

Some advanced solutions allow users to search MSG attachments and review attachment related information easily without opening each email separately. This feature becomes particularly very useful when your important information is stored in attached documents rather than in the body of the email message.

Search by Email Header Information

If you are an advanced user then you may need to search using some of the technical characteristics of emails and these are the following:

  • Message ID
  • Internet Headers
  • Routing Information
  • And Domain Details

And let me make it very clear to you that this capability is mostly utilized by IT administrators, forensic investigators and also used by compliance teams.

Search Multiple MSG Files at Once

Checking individual emails one by one can be absolutely frustrating and time consuming so you can simply perform searches across an entire MSG archive in one go. This allows you to search Outlook MSG files using multiple criteria which you can see below in example:

  • Sender + Date
  • Subject + Keyword
  • Recipient + Attachment Name
  • And Date Range + Email Content

And if you are using filters multiple times it can produce faster and more accurate search results for you when having the large email archives. Challenges of Searching MSG Files Manually.

Challenges of Searching MSG Files Manually

However you can open MSG files individually with the use of Outlook and searching through a large number of files can present several challenges these are:

  1. Opening each file one by one is very slow and inefficient.
  2. There are chances that Windows Search does not always index MSG file content properly.
  3. Attachments in the MSG files are usually extracted from standard searches
  4.  And finding keywords across thousands of files is nearly impossible that too manually.

Outlook does not provide any dedicated feature for its users which they can use to search for multiple different MSG files stored within its folders. So as a result many users look for better ways to search text in MSG files and retrieve relevant emails quickly.

Ways to Search MSG File Content and Find Keywords in Outlook Emails

Searching MSG files is essential when you need to locate your specific emails, keywords, senders, recipients, dates or you need any attachments. Below are the most effective ways to search MSG file content and find relevant Outlook emails quickly as per your requirement.

Method 1: Search MSG File Content Using Windows Search

  1. Open the folder containing MSG files.
  2. Click inside the Search box in File Explorer.
  3. Enter the keyword you want to locate.

  • Your search results may be incomplete.
  • If you have a large archive then this can produce slow results.
  • Attachments are typically not searched.
  • And results vary depending on Outlook installation.
Important: There are many users who find that Windows Search sometimes fails to find content inside MSG files and this is especially after system updates or when Outlook is not installed in their system.

Method 2: Open and Search Individual MSG Files in Outlook

Another option for you is to open each MSG file separately by using Microsoft Outlook.

Steps

  1. Double click the MSG file.
  2. Open the email in Outlook.
  3. And press (Ctrl + F).
