Having hassles with oversized Outlook PST files. Even today, this is a common problem and when it happens, it can render your Outlook completely useless. It was more prevalent in the older versions, but since many users are still on these versions, it is important to know how to repair.

When using PST files, there was a filesize limit of 2Gigabytes. This was updated as of Outlook 2003, but it also depends on the filesystem as ANSI files could only support a maximum size of 2GB. Listed below are the versions that suffered worst from this problem:

  • Microsoft Outlook 2000 Standard Edition
  • Microsoft Outlook 2002 Standard Edition
  • Microsoft Outlook 98 Standard Edition
  • Microsoft Outlook 97 Standard Edition

While versions of Outlook 2003 onwards no longer have the 2GB PST limit on Personal Folders, but the limit still applies to IMAP accounts. The only way to get around the IMAP restriction is with Outlook 2007. This now allows for HTTP and IMAP accounts to use unicode, therefore the 2GB limit does not apply. However, unless you can install the latest version, you need to know how to repair the problem and avoid it in future.

How to Detect and Repair Oversized PST

Having an oversized PST file is very frustrating, because it is not reported. Generally the mail will just freeze, or it will seem to be working normally, but you won’t receive any new emails. This makes it very tricky to debug and it can be a real headache, as we usually check all the other problems first.

If you stop receiving email, start first by checking the filesize of your PST. If is very close to the 2GB mark, that is most likely the issue. In order to address the problem, you need to delete emails or archive mail. Sometimes you might need to delete the messages directly from the server if your account is completely locked. Fortunately, there are tools that can split and repair oversized PST files. Something like Stellar PST Repair can do this quite well and it can be safer than tampering with the files yourself.

It is recommended that you archive mails on a regular basis and never let your inbox get too large. It will make email management easier and safer. You will also avoid issues such as inbox corruption.
