Advantages & Peculiarity Of Variant Features

  1. Add PST Files Individually Or Collectively

    The software gives two options to add the PST files in the software. The user either can add PST files one by one by Add Files option or can add a folder containing multiple PT files with the help of Add Folder option.

PST Merge: Add Folder

Advantage: The Add Folder option is very convenient for the users as it saves the user’s time that is consumed for browsing the PST files individually. Selecting this option adds all the PST files at once.

  1. Variant options For Combing PST Files
    The software offers three distinct options for combining the PST files. They are:
  • Merge

This option consolidates the PST files by merging the similar folders of all the PST files. For example, the inbox folder of all the input PST files will be merged into a single Inbox folder of the resultant PST file.

PST Merge: Merge

  • Join

The Join option combines multiple PST files into a single PST file wherein each input PST file are denoted by separate folders. For example, 2 PST files are joined; the output PST file will have two folders named as Personal Folder [1] and Personal Folder [2].

PST Merge: Join

  • Merge Contacts

Merge Contacts option will only merge the contacts of the input PST files and store the contacts in a single folder of the output PST file.

PST Merge: Merge Contacts

Peculiarity: The users at times get confused with the different merging options, specially the Merge and Join option. The differences between the two options get clearer when the user runs the software on his own.

  1. Remove Duplicates

The Remove Duplicates option enables the user to remove all the duplicate items like emails, contacts, calendar entries, etc. from being merged together. When enabled, the user will automatically remove the duplicate items and will only keep the original item in the resultant PST file.

PST Merge: Remove Duplicates

Advantage: This option saves the user from getting confused due to duplicates of a single item. Since duplicate entries create a lot of confusion, this option saves the user from it.

  1. Exclude Deleted Mails

The software gives the user a choice to exclude the mails that have been deleted and are stored in the Deleted Items folder. This enables the user to exclude the unnecessary mails from getting merged.

PST Merge: Exclude Deleted Items

Advantage: This feature is helpful for the users who do not want to increase the size of the resultant PST file due to deleted emails. In addition to saving the space, it also saves the time of the complete merging process.

  1. Create New Folder to Store PST

The software allows the user to save the resultant PST file at the desired location. In addition to this, the user can also create a new folder from the software panel itself.

Advantage: This option is helpful in the scenario when the user has not created a folder to store the resultant PST file beforehand.

The Verdict

PST Merge is an impeccable tool to merge multiple Outlook data files, embedded with all the features that are essential in a PST merge tool. Even though the software does not give a preview of the input PST files it does give a plethora of different features to make the merging process easy and convenient.
