PST management is always a matter of deep concern for Outlook users. It’s a standout amongst the most widely recognized issues what Outlook users frequently confront. Whatever you have large in number, is always challenging to handle or manage. For any Outlook user, it becomes challenging if he/she has multiple PST files. As the files are in large number, you have only one solution: merge PST files into one file.
Outlook PST file is not immune to corruption. The primary reason for corruption is PST size limit. Outlook PST file has a definite size limit, i.e. ANSI PST file can store up to 2 GB of the mailbox; Unicode PST file has a size limit of 20 GB to 50 GB. ANSI is the default file format of PST files created in Microsoft Outlook 2002 and its earlier versions. While Unicode is the default file format of PST files created in Microsoft Outlook 2003 and its later versions. Due to such size limitation, if an ANSI PST file stores more information than its size limit, then risks for its corruption turn out to be high. The same issue can be knowledgeable about a Unicode PST file. A Unicode PST file can amass to 20 GB of mailbox data and in Outlook 2010 or later version, it can accumulate to 50 GB.

How to merge PST files Outlook 2010?
Microsoft Outlook client has no built-in feature or function to merge two PST files or multiple PST files directly into a single file. But you can try an easy manual trick to import mailbox content from multiple PST files into a single file. You can simply perform the manual trick by using Import feature of Microsoft Outlook client.
Step 1: Launch Microsoft Outlook on your system.
Step 2: Create a new Outlook data file.
Click New Items, point to More Items and click Outlook Data File….
Step 3: On the Create or Open Outlook Data File window, give a name to this new file.
Click OK to confirm your action.
You can see the new Outlook data file in the navigation pane.
Step 4: Now click File tab > Open > Import.
Step 5: On the Import and Export Wizard, select Import from another program or file in the option. Click Next.
Step 6: On the Import a File window, select Outlook Data File (.pst).
Now click Next.
Step 7: On the Import Outlook Data File window, click Browse to locate the file and select it.
You can see the selected file in the edit box. Also, check the Do not import duplicates box, and then click Next.
Step 8: Select the folder to import from.
Check the box Include subfolders and Import items into the same folder in.
Finally, click Finish.
Step 9: Outlook starts importing the selected mailbox folder to new PST file.
It’ll take a couple of minutes (maybe more than that) to complete the process successfully. Now you can check the PST file created recently. As a result, you’ll see all the imported mailbox folders are available in this new PST file. Now you need to perform the same trick for other PST files as well.
Unluckily if the Outlook PST file is corrupt, you can’t import PST mailbox content from it manually. You must have a valid PST file in order to use the above manual trick. If PST files are valid, i.e. not corrupt, you can easily open the files and import their mailbox into a single file. But if the PST file is corrupt, you must repair it first.
