What is an oversized PST file?

Basically, a personal storage table (PST) is a central repository of MS Outlook elements including emails, contact items, calendars, drafts, notes, tasks, journals etc. Typically, both the PST file and outlook data files (.ost) possess greater file size limits in Outlook 2010 and 2013 (because of their Unicode format) as compared to its previous versions including Outlook 2002, 2003, 2007 etc.

When a PST file exceeds a specific storage limit, it gets oversized and problems may arise thereafter while accessing mailbox folders and email messages. In such a scenario, your MS Outlook application may throw the following errors –

  • Reported error 0x00040820 – This error may occur while sending/receiving emails via a specific email account in Outlook 2010. It appears when a user attempts to synchronize mailboxes with an outlook data file that crossed the standard file size limit.
  • Background Synchronization errors – These errors generally take place while syncing mailboxes from one Outlook version to another and there is a mismatch between the size of the older and the newer .PST file.
  • “The file abcd.pst has reached its maximum size. To reduce the amount of data in this file, select some items that you no longer need, then permanently delete them” occurs whenever your PST file crosses the maximum limit allowed in that particular version of MS Outlook.
  • File Access Error – The error “abcd.pst cannot be accessed – 0x80040116” occurs when the Outlook data file becomes corrupted or damaged due to file oversizing issues.
