PST Split & Merge

Repair Your Oversizing PST File Corruption Issues to Avoid Mailbox Inaccessibility

MS Outlook is a commonly used emailing application by both home individuals as well as business professionals. In order to store your complete mailbox information, this application uses Outlook data files, which includes personal storage table (PST files). However, users may sometimes face common problems of application sluggishness, hang or crashes due to the oversizing of PST files. Therefore, the management of PST files becomes an imperative job for the smooth running of Outlook application.

MS Outlook has rolled out relevant changes with its each subsequent versions. To understand and resolve the issues of PST file corruptions, you better need to know what causes the restrictions in personal storage folders. PST files are classified in two different formats, i.e. ANSI PST and Unicode PST to store the mailbox data in Outlook data files.

ANSI PST format: The earlier versions of MS Outlook including 2002 supports ANSI PST format, and restricts users to store only 2GB of file size data. When the PST file crosses the predefined limit of 2 GB, then it creates a favorable environment for PST file corruption.

UNICODE PST format: This Unicode PST format is supported and understandable by the versions of Outlook 2003 and higher. However, this Unicode PST format has bigger database storage file size capacity than ANSI format but it should not exceed the limit size of 20 GB. Otherwise, the PST files may get damaged and Outlook will refrain users to access any of it.

When Outlook file reaches to the specified capacity, it restrict users to add further new data in it. Also, the users is restricted to perform any operations such as create notes, perform send/receive operations, set appointments etc. until the data is being shifted to some other location.

The large-size PST corruption is an inconvenient situation and you need to split PST file in order to free the respective space to resume to the normal Outlook functioning.

Common things that may happen when PST file crosses the limits

  • Unable to send or receive emails
  • Outlook starts to show sluggish responses
  • Outlook PST files get corrupted
  • MS Outlook application hangs before closing
Know Your Corruption Condition (Symptoms)

Below listed is some of the error messages that users may encounter due to the over-sizing of PST files.

The error messages is showcased when users try to add emails or other items in the mailbox, and it goes beyond the 2GB PST file size limitations. The Outlook refrains to accept any new information and showcases the following error messages:

  • "The file could not be added to the folder. The action could not be completed"
  • "Task 'Microsoft Exchange Server - Receiving' reported error (0x8004060C): 'Unknown Error 0x8004060C'"

Users may face the below mentioned errors when tried to access or load a large-size PST file.

  • "Errors have been detected in the file xxxx.pst. Quit all mail-enabled applications, and then use the Inbox Repair Tool"

Unfortunately, Outlook offers no built-in option to deal with the inaccessibility issues created by over-sized PST files. But, it do provide an external PST2GB utility to repair the files to usable status. However, this tool is not a foolproof solution to attain accurate pst split & merge operation.


Try using the three of the available solutions by Outlook, if you are about to reach the limited storage criteria.

  • Import & Export
  • Archive PST
  • Move to folders

Archiving is the most reliable and hassle-free option of all the three solutions, and it also works as a backup for your important mailbox data.

Implement the following methods to archive your emails and in order to make them shift in a PST file.

  1. Launch Outlook 2007.
  2. Go to file menu and Click on Archive tab
  3. Archive Window will appear with default setting of Archive this folder and all sub folders option. You may also select other option of "Archive all folders according to their auto archive settings" as per your specific requirement.

  4. Select "Archive items older than"settings and provide the respective date from which you need to archive the previous items.
  5. Provide the desired path for 'Archive files' or let the default the archive file path as C:\Users\phill\AppData\Local\Microsoft\Outlook\archive.pst
  6. Click on'OK' button and archiving process will initiate.

After finishing the archiving process, you may now free the mailbox space by deleting the inbox. However, you have just taken a backup and now you have to split the backup PST file as well. But MS Outlook doesn't provide any PST split tool that can easily perform pst split & merge operation. Hence you require external splitting utility.
