Understanding Pst And .Ost Files

PST (Personal Storage Table) and .ost (Offline Storage Table) files play a crucial role in managing emails, contacts, calendars, and other data in Outlook 365. PST files are used for storing data on a local device while .ost files synchronize data with the Exchange server. Understanding the differences between these file types is essential for effectively configuring size limits.

PST files are prone to corruption if they exceed their size limit, causing potential data loss and performance issues. On the other hand, .ost files are more resilient to size limitations due to their ability to sync with the server. By comprehending the distinctions between these files, users can implement appropriate strategies to manage their mailbox sizes efficiently.

Configuring size limits for PST and .ost files involves setting appropriate thresholds to ensure optimal performance and data integrity. By grasping the fundamental purposes of these files and the impact of size restrictions, users can streamline their Outlook 365 experience and avoid common pitfalls associated with exceeding storage limits.
