But, before having an in-depth discussion about the methods, let’s first get familiar with the Outlook data file(.pst) and why it tends to get corrupt easily.

Brief Introduction of PST file

PST files store copies of emails, contacts, calendars, tasks, journals, and other items. It comprises a folder structure and a number of individual items. Here, emails often have a large size compared with other items since they contain attachments.

If you talk about the size of the PST file then it can go up to certain GBs. Through the ‘Auto archive’ feature in Outlook, you can create PST files. Further, this file format is easily portable.

But, What’s Problem With PST files?

Well, frankly, the PST file is not a robust file format and is considered highly fragile. The design of this file format is unreliable for the long-term storage of a massive amount of data.

Furthermore, PST files are prone to data corruption which is the real concern of many Outlook users.

In What Way PST Files Get Corrupted?

Abnormal Termination: When you frequently open and close the Outlook application or if your computer system terminates abruptly then there is a chance of PST file corruption.

Oversized PST: As discussed earlier, PST files can’t store large data files. And, the way data is growing these days, PST files often exceed their maximum limit(approx 20-50 GB). Particularly, this makes them liable to corruption.

PST files shared through networks: Sometimes, in organizations, to access a common PST file, it’s put on a server and shared via networks. This simultaneously leads to data corruption. And, when the file size is larger, the chances of file corruption are higher.

When you have heavily corrupted PST files, it shows the following error messages.

“Errors have been detected in abc.pst file”
“The abc.pst couldn’t be accessed.” “Unable to open abc.pst file. Access denied.”
