How long does it take to merge large PST files? - AlexisTorres - 10-25-2025
The time it takes to merge huge PST files is mostly determined by the file size, system performance, and the number of PST files to be combined. In general, merging a few GB can take a few minutes however merging really big PST files (50GB or more) can take longer. To simplify and speed up the process, utilize the DataVare Outlook PST Merge Expert Tool which quickly merges several PST files including emails, contacts, calendars, and attachments into a single, well organized PST with no data loss. The application supports both ANSI and Unicode PST files, works with all Outlook versions and allows you to merge, join. It is a great choice for anyone looking to speed up mailbox management and eliminate Outlook waste.
