Case Study: How Softaken Helped an Organization Identify and Remove Duplicate MSG Files in Bulk

The IT team’s goal was simple: clean up an old Outlook email archive before it became even more difficult to manage.

For years the organization kept emails as MSG files. These files were pulled from employee backups, Outlook exports, project folders, and previous email migration efforts. Over time the archive grew to be filled with repeated copies of the same messages.

At first, the duplicate files weren't a big deal.

The archive then grew into thousands of message files.

It became more difficult to find unique emails and the storage consumption increased, making routine backup operations take longer. The IT team knew that manually checking each MSG file was no longer feasible.

They needed an easy way to find and delete duplicate MSG files while keeping the original email data safe.

Here Softaken MSG Duplicate Remover came into the cleanup process.

The Organization's MSG Archive Problem

The main communication tool of the organization was Outlook on a day-to-day basis. Key messages were exported regularly and saved as MSG files for future reference.

Every department had developed its own means of maintaining these archives.

Some workers kept their own emails. Others copied complete Outlook folders. IT admins did backups every now and then, and older MSG folders were copied here and there during system upgrades or migration projects.

The result was predictable: the same email could be found several times in different places.

The archive included:

  • Communications to customers
  • Project e-mails
  • Internal communications
  • Vendor discussions
  • Economic discussions
  • Outlook email backup
  • Business records on file

There were many unique messages in the old folders, so the organization couldn’t just delete them.

Redundancy was the real problem, it wasn’t the age of the data.

Why Manual Duplicate Removal Was Not Practical

First the IT team thot about doing a manual clean-up of the archive.

It seemed like a simple process:

  • Open an MSG file.
  • Check sender and recipient.
  • Look at the subject and the date.
  • Message read.
  • See attachments if necessary.
  • Compare it with other files.
  • Remove the duplicate.

That approach works if there are only a handful of MSG files.

That’s another story when the archive numbers in the thousands.

The team also discovered another problem: filenames were not a reliable identifier of duplicates.

For example, the same e-mail may be in the following files:

Client_Request.msg Client_Request_Copy.msg Client_Request_Final.msg

At the same time, two files with very similar names could contain two different messages.

A simple Windows file search didn’t do the trick.

The Organization's Approach

The IT team backed up the original MSG archive before starting the cleanup.

This was an important safeguard.

The organization wanted to purge duplicate data but didn’t want to risk losing a critical business email in the clean-up process.

After securing the original archive, the team then looked at a dedicated MSG deduplication approach.

They chose Softaken MSG Duplicate Remover to find duplicate emails and bulk process them.

The goal was not only to delete files.

This was to establish a controlled process:

Scan → Discover → Check → Delete → Confirm

Step 1: Preparing the MSG files

First, the IT team checked the existing folder structure.

Instead of dumping all the MSG files into one big folder they categorized the data around existing departments and archive categories.

This made it easier to clean up.

For instance, the team could collaborate with:

  • Sales archives
  • Customer service binders.
  • Archives of Projects
  • Emails on finance
  • Backups of Employes
  • Older Outlook exports

Step 2: Adding MSG Files for Scanning

The team launched Softaken MSG Duplicate Remover and added the concerned MSG folders.

It was important to support working with multiple files, because it would have been pointless to select thousands of MSG files one by one with a dedicated cleanup solution.

The selected folders were ready for duplicate scanning.

Nothing was deleted by the IT team at this stage.

The purpose was just to see if there were any duplicate e-mails.

Step 3: Identifying Duplicate MSG Emails

The software searched the selected MSG files and identified duplicate email messages.

This was a major step up from filename-based searching.

You can rename, copy or move an MSG file without changing the email inside it. So duplicate identification needs to look at the email data, not just assume the filename tells the whole story.

Now the organization could look at groups of duplicate messages rather than comparing thousands of files manually.

Step 4: Removing Duplicate Files in Bulk

Once the team was satisfied with the duplicate results, it turned to the cleanup.

Instead of deleting MSG files one by one, the organization could bulk process the found duplicates.

This made the repetitive work considerably less.

The team no longer had to spend the majority of its time opening emails and manually comparing them.

The cleanup replaced the long manual investigation with a structured archive-maintenance operation.

The Results

After the cleanup was done, the organization had a much cleaner MSG archive.

The project has led to a number of practical improvements.

Duplicate Data Was Reduced

Duplicate copies of the same email were eliminated thus decreasing unnecessary data in the archive.

Storage Became Easier to Manage

By removing unnecessary files, the organization was able to better utilize its storage space.

Backup Operations Became More Efficient

Future backups will not need to store the same email over and over again in duplicate copies.

Email Archives Became Easier to Navigate

Removing duplicate messages helped in finding relevant messages.

IT Staff Saved Time

Now the team didn't have to comb through every MSG file to find repeated emails.

Why Softaken MSG Duplicate Remover Was Useful

The organization chose Softaken MSG Duplicate Remover because the problem was only MSG duplicate emails.

The software provided a streamlined workflow for:

  • Scanning multiple MSG files
  • Detecting Duplicate Emails
  • Handling large collections
  • Reducing manual comparison
  • Eliminating unnecessary duplicate copies
  • Cleaning Your Outlook Email Archives

The IT team’s principal value was efficiency.

They don’t need a complex email management platform. They were looking for a practical solution for managing duplicate MSG files, and a dedicated utility fit the bill.

Final Thoughts

There was no lack of storage at the organization, they had way too many important emails. It had a storage problem because the same emails had been saved again and again over the years.

The manual clean-up would be too slow, and deleting entire archive folders would be risky.

IT team could use Softaken MSG Duplicate Remover to scan and find duplicate MSG emails in bulk, review the results and delete unnecessary copies in a more managed way.

The biggest lesson is simple: cleaning an email archive doesn't mean deleting old data. Sometimes the best improvement is to delete the redundant copies and keep the unique messages.

Manual cleanup might still be okay for a small collection. However, for organizations with thousands of Outlook MSG files, bulk duplicate detection can make the process fast and easy to manage.
