Storage Space Overload
Each duplicate email stores gigabytes of disk space in your system. If thousands of business emails are exchanged daily, they occupy a lot of space. Deleting these duplicate email files frees up storage space as well as organises your mail box neatly.
Slow Email Client Performance
Duplicate emails cause email clients to consume a lot of resources and indexing, synchronization, and search operations. This can cause hanging, slow replies, etc. EML deduplication helps to helps keep the mailbox organized and easier to manage.
Compliance and Legal Archiving
Accuracy is vital for compliance, regulatory and legal mail archiving. Archived mailboxes become larger with duplicate emails, making eDiscovery more difficult. Clean up duplicate EML files to be compliant and accurate.
Cleaner Email Migration
Before migrating EML files, remove the duplicates for a smooth migration of mailbox contents. If thousands of email duplicates in the mailbox cause a rise in mailbox size and transfer time, then deleting duplicate EML files gives you a cleaner EML migration.
Choose the right mode to address your specific need or use both for a thorough deduplication.
Within Folder
The method individually scans each folder and then delete duplicate EML messages in that specific folder.
Across All Folders
Analyses all the EML files in all folders and subfolders for deleting all of the duplicates present in that mailbox.
Selective Processing
With the help of selection options, users can set their own rules on how to search for duplicate EML files. Choose the desired settings of any of the EML properties: From, To, Cc, Subject, Message Body, Attachments, Date and Time. The tool uses only the checked attributes to detect identical EML messages.
For example, if two EML messages carry exactly the same sender, recipient, subject and message, the tool will search for duplicate EML messages and remove them, even if they are in separate locations.
Date Range: To make the filter process of identifying the duplicate EML files easier, the date range filter is included to choose the desired time period by defining the start and end date. The filter is also effective for excluding those old, outdated and non-relevant EMLs, so there will be more chances for deleting relevant and important duplicates.

It's astonishing how they search every hard-to-find file in entire email files using this tool. Now my EML files are much less in size. Additionally, it created a new file without any duplicates, which is such a great deal.
