If you have more than one account in Outlook or multiple PST files that you often open in Outlook to access mail items, you can merge them using the software to create a unified PST file. This way, you can access all mail items from one PST file in Outlook rather than opening multiple PSTs.
Stellar Merge Mailbox for Outlook software removes duplicate mail items, such as emails, contacts, attachments, notes, tasks, etc. while merging two or more PST files. This helps prevent inflating the final PST file with duplicates and makes it easier to manage.
Many times you may have backups of old email accounts in PST files that could be large and could not be merged by manual methods. In such cases, you can use Stellar’s merge mailbox tool to combine large PST files in a few clicks with complete integrity and precision.
The tool can merge multiple PST files, including emails, calendars, contacts, journals, notes, etc. into a single PST. It maintains the original folder structure and contents while merging the information of multiple ‘matching’ folders. The software also allows merging the user-specified mail items from PSTs without the need to merge the complete PSTs.
Stellar Merge Mailbox for Outlook can also ‘join’ PST files of different Outlook versions. The software joins the PST files by generating root folders for holding the child folders from source PST files. It organizes the child folders in a structural hierarchy in the final PST while preserving the original contents after combining the files.
The merge PST software allows the merging or joining of Outlook PST files of any size – small or large.

While merging large PSTs, the software retains the original folder structure and mailbox hierarchy.

It can remove duplicate items based on Subject, Sender Email, Text, Sender Name, Recipient Name, Internet Header, Attachments, and Date and Time of Sending. It provides Default and Advanced Duplicate Criteria to remove duplicate items effectively.
The software allows the user to exclude Deleted and Junk Items folders while merging PST files. This feature helps remove unwanted or scrapped items, thereby ‘cleaning up’ the data stored in the final, merged PST. The user can enable the option by clicking Exclude Deleted Folder and Exclude Junk Folder checkboxes.
The tool provides multiple options to save the merged or joined PST files. It can save the PST file in a new or the existing PST, Outlook profile, Office 365, or Exchange server. The user needs to select the output option while saving the final PST and specify the location to save the file. For Office 365 and Exchange servers, the user needs to enter the login credentials and also the mailbox email ID and server name (when saving to Exchange).
The utility can merge password-protected PST files of the Outlook email client. The user needs to enter the password for merging the PST files. The feature allows seamless merging of multiple password-protected PST files.
