Why Should You Merge PST Files?

It’s very common to have more than one or multiple PST files in the Outlook profile. Generally, 5 to 10 PST files seem normal. But if they’re large in number, you may find PST management and files handling very difficult.

  • A large number of PST files may get misplaced somewhere or lost due to accidental deletion.
  • If you want to access the mailbox data stored in the multiple PST files, you need to open them one by one. It’s definitely a lengthy and time-consuming process.
  • If you need to share the multiple PST files over the network, it takes more than enough time in transferring the files one by one.

How would you deal with a situation where PST management becomes difficult for you? You can simply merge PST files into a single file so that you won’t face any management issues at all. Instead of multiple PST files, it’s better to keep one main PST file which you can easily open, handle, and manage with no problem. The question now arises, how to merge PST files. Well, there are two different methods you can use here: either a DIY trick or a professional PST Merge tool.
