What is oversized OST file problem?

Microsoft Outlook 2002 and lower versions limit the size of offline folder (OST) file to 2GB. When the file reaches or exceeds that limit, you will encounter the following errors:

  • Cannot open or load OST file at all.
  • You can see various error messages during the synchronization process.
  • Cannot add any new data to the OST file.
  • Cannot synchronize the OST file with Exchange Server.

Microsoft Outlook and Exchange Server have no built-in functions to rescue the oversized OST file. Microsoft only released several service packs so that when the OST file size approaches the 2GB limit, Outlook will show some errors and stops accepting new data. This service mechanism can prevent the OST file from getting oversized to certain extent and prevent OST file corruption. But once OST file exceeds its limit, you can’t do anything with the OST file such as send/receive emails, make appointments, write notes, synchronization etc. unless you remove bulk of data from OST file and compact it subsequently to reduce its size to less than 2GB. This is very inconvenient when OST file grows larger and larger.

The solution for oversized OST file is to split the oversized OST file into several smaller PST files. Each PST file contains a portion of the data in the original OST file, but it is less than 2GB and independent from each other, so that you can access it separately with Outlook 2002 or lower versions. But this method is little bit incontinent as you need to manage multiple PST files after split operation. You may still face the same oversized problem when any PST file reaches 2GB later.

Once your 2002 OST file becomes oversized, then it will get corrupted and you can’t access you Outlook profile. At this time, you need to convert OST file to PST file by using a professional OST to PST converter tool. This software will fix the corrupted OST file while converting it to accessible PST file. Later on, you can import the newly created PST file to regain you emails and other Outlook items.
