Outlook.pst before Outlook version 2003 follows ANSI (American National Standards Institute) standards, according to which the maximum file size limit for PST can be 2GB. On reaching this limit, Outlook.pst generally crashes out leading the Outlook user in data loss, as MS Outlook cannot access the damaged Outlook.pst file. This is when the PST crosses 2GB; but when PST if about 1.5 GB or more, Outlook starts performing very slowly. To resolve the issue, the size limit for PST is increased in Outlook versions 2007 and above and now the PST can grow up to 20GB.
Even when the maximum size limit for the Outlook.pst has been increased, there is no solution done to improve the Outlook performance due to large size PST. Oversized PST generates an array of issues that are listed below:
- Outlook takes a lot of time to start.
- It hangs up so many times when you perform an operations
like creating email, receiving email, viewing attachments, etc.
- Considerable slow performance generates error messages like
""Errors have been detected in the Outlook.pst," "Can't Copy
the items. The file %PST file name% has reached its maximum
size. To reduce the amount of data in this file, select some
items that you no longer need, then permanently (Shift+Delete)
delete them," etc.
- Chances for the PST damage are increased to a considerable extent.
Mentioned-above are the issues that come across your way due to large sized Outlook PST. This means, you need to decrease the size of PST, if you want to overrule the specified issues otherwise the effect can be worst as losing all emails, notes, contacts, meeting schedules, etc. Therefore, to save yourself from data loss, divide Outlook files into small PST files.
