Designed to enable Outlook users to merge many PST files into one consolidated file, the GainTools Merge PST Tool is a strong Windows-based tool. Ensuring compatibility across all major editions, including Outlook 2019, 2016, 2013, 2010, and earlier, it supports both ANSI (older Outlook versions) and UNICODE (newer Outlook versions). Without changing data integrity or folder structure, the application manages the merging of whole mailbox data, including emails, contacts, calendars, tasks, notes, and journals. Advanced filtering choices enable users to create a new custom folder or combine PST files depending on the kind of folder. Outlook’s independent capabilities eliminate the requirement for installation during the merging process. This utility is especially helpful for IT administrators and data managers looking to optimize storage and simplify PST file management. Its simple processes and clear UI let even non-technical users effectively execute the merging with little instruction. Use the free demo edition to check out the application.
