Limitation of Manual Method

As we mentioned above, the manual approach to merge multiple PST files into one in Outlook 2016 is not suitable for many users. It has various limitations that make this approach inappropriate for non-technical users. We explain some major limitations of the manual approach.

• It is quite complicated and time-consuming. You must have the required technical expertise in the respective field.
• The chances of file corruption are high. If you fail to perform the steps correctly, you may end up losing your mailbox items.
