Technical Overview


MS Outlook is one of the commonly preferred email clients being used at an enterprise level that stores its database in two file formats- OST and PST. Outlook supports both files, but their functioning is different from one another, with the role of Exchange Server associated with one of them. However, we will be dealing with only files, corruption issues & ways to recover data using OST Recovery Tool.

OST files come into action only when the Exchange server configures the Outlook profile by enabling the MAPI protocol. This file contains the replica of data that resides on the Exchange server, which acts as a depository storing all mailbox data like emails, calendars, contacts, etc.

Common Issues with OST Files

Issues in OST files are often generated when the files undergo corruption. To restore the data from such files, they must be repaired using the Recovery Tool. Here are some of the issues that are associated with OST files:

  • Exceeding the Size of OST:- OST file is associated with a limited size & maximum storage of 50GB. These files start facing performance issues when their size reaches around 45 GB, like slow working, Outlook hangs while opening, leading to OST file in corrupted mode.
  • Synchronization Issues:- Any disturbance in the synchronization process with the Exchange server may lead to the corruption of the OST file. Some reasons for the synchronization problem that leads to corruption are due to power failure, maintenance issues with the Exchange server & mismatching of the encryption key.
Common Errors Due to Corrupt OST

If the OST files are corrupted, it disturbs the normal functioning of Outlook & users face several error messages while using Outlook. Some of the common errors are as follows:

  • Error 1: This Outlook error is shown when there is any issue related to synchronization with the Exchange server. The possible reason for this error is when the server fails to recognize the corrupted OST files.
