Microsoft Outlook is an amazing email client platform to perform real-time collaborative services, such as web browsing, task management, contact management, blogging, along with seamless email services. The MS Outlook email services are highly available because of the integrated Exchange Server environment. All Outlook user accounts, security policies, configurations reside in the central repository, i.e. Exchange Server. Furthermore, to make the email communication highly available, Outlook offers an exquisite facility to create and maintain offline folders that holds crucial email data in OST format file. You can access email items when your MS Outlook client gets disconnected from Exchange Server by accessing the contents available in the OST file. All OST email items get automatically synchronized with Exchange Server once connection with MS Outlook is established.

However, MS Outlook imposes several restrictions over the size of OST mail items with the help of four distinct registry entries. Each registry entry if exceeds the default limit can corrupt the entire OST email items. Let us explore the Outlook registry entries to know recommended size limits for avoiding any OST corruption.

Acknowledge Outlook Registries Default Settings to Avoid OST Corruption

Microsoft Outlook maintains the following registry sets to confine the size of .ost and .pst file.

  • MaxFileSize registry: The MaxFileSize registry entry defines the maximum size of OST or PST file, which couldn’t be exceeded without any data loss. It is affiliated with the ANSI format file.
  • WarnFileSize registry: The WarnFileSize registry specifies the maximum data OST and PST file can possess. After reaching this limit, one cannot add more items in the respected OST or PST file. It supports the ANSI format file system.
  • MaxLargeFileSize registry: The MaxLargeFileSize registry works exactly same as the MaxFileSize registry but it works for the Unicode file format.
  • WarnLargeFileSize registry: The WarnLargeFileSize registry works, similarly as the WarnFileSize registry, by stating the maximum email items that OST and PST can have but it is specifically used for Unicode file systems.

Getting a brief idea about the MS Outlook registry entries would help you in saving the OST corruption by ensuring the appropriate size limits. Moving further, to get an exact information about the default Outlook size limits, let’s look at the following informative table:

Registry Entry Default Range Actual Data Range
MaxFileSize 0x7BB04400 2,075,149,312 – 1.933 GB 0x001F4400 – 0x7C004400
WarnFileSize 0x74404400 1,950,368,768 -1.816 GB 0x00042400 – 0x7C004400
MaxLargeFileSize 0x0000C800 51,200 – 50 GB 0x00000001 – 0x0000C800
WarnLargeFileSize 0x0000BE00 48,640 – 47.5 GB 0x00000000 – 0x0000BE00

The above mentioned tabulated information is specifically illustrated for the latest MS Outlook 2013 and MS Outlook 2010 versions. To add further, several intrinsic software malfunctions or Windows error impacts the standard Outlook registry entries which poses a great risk to the integrity of OST file. However, one can easily learn to fix the Outlook registry settings when certain anomaly occurs in the configured Outlook registries.

  3. In the Registry Editor window, expand My Computer or Computer followed by HKEY_CURRENT_USER
  4. Expand the Software option, and then click Policies
  5. Moving further, drop down Microsoft and expand Office
  6. Now, if you have MS Outlook 2013, 2010, 2007, or 2003 installed, then expand 15.0, 14.0, 12.0, or 11.0, respectively
  7. Select the PST option and right-click MaxFileSize.
  8. Click the Modify option, and then configure the appropriate value in Value data. Click OK.
  9. Similarly, configure the data values for WarnFileSize, MaxLargeFileSize, and WarnLargeFileSize options

There are many cases where entire OST mailboxes gets corrupted because of the violation of default file size limits. The OST corruption once originated couldn’t be prevented by configuring the data values as depicted in the preceding procedure. For such scenarios, getting an expert third-party solution to recover OST files is the need of an hour.

Solution – OST to PST Conversion Tool

OST to PST Tool is the professional solution to repair and then convert corrupt OST email items into authentic PST format file. The software is geared with advanced migration capabilities that allows you to save repaired email items on popular email servers, cloud services, web-based email apps, etc. In addition, the software has the utmost compatibility towards the latest Windows 10, Exchange Server 2016, and MS Outlook 2016 platforms.

Outlook users often come across oversized OST file issue while using it with Exchange server. With every version of Outlook, Microsoft defined a storage limit for Outlook files OST and PST. Outlook version 2002 and its previous versions have maximum storage capacity of 2 GB, then Outlook version 2003 and 2007 can store upto 20 GB of data. Thereafter, version 2010 and latest versions have a storage limit of 50 GB. If user exceeds these specified storage capacities then one or more OST file errors can be encountered, such as:

  • Cannot accumulate data in the existing file
  • OST cannot be synced with exchange server
  • Cannot open OST folder
  • Synchronization process cannot be executed
  • Multiple error messages throughout Exchange Server and MS Outlook synchronization
  • Errors detected in particular file. Quit running application and utilize Inbox repair tool

Outlook Users Dilemma

While using preliminary versions of Outlook (2002 and previous versions), where storage limit was 2 GB, users face extreme data loss due to OST file oversize issue as, no inbuilt option was available to recover the lost files. The system would just show up some errors and rejects new data to be added. Considering the helplessness of users, Microsoft introduced new version 2003 supporting UNICODE format with saving capacity of 20 GB. Moreover, it added an inbuilt repair tool named scanost.exe to repair corrupted OST files in case they exceed storage limit, along with various other methods to recover OST files from this issue. Subsequently, following version were improvised with additional recovery features and increased storage capacity, which is 50 GB by now as per the latest version.

Implementation of Inbuilt utilities and modification in Outlook settings

Native tool scanost.exe is capable of fixing different OST file issues. Modifying registry settings is also recommended in such a case. User can revise the max file size registry entries or warn large file size registry entries for adjusting the storage limit of the Mailbox. Modifying storage limit of mailbox would only inform you upon excess usage of defined space and would suggest you to delete unnecessary items to make some space for new Outlook items. Even OST crop tool can be installed for resolving oversize issue. But all these methods won’t retrieve the whole database. Instead it would retain files upto a limited size and would delete the entire database above that limit. So, user might lose some important data in such processes.

Requirement of Third party OST converter Tool

For retaining complete OST database, which is lost due to oversize issue, user has been left with only one option now and that is utilization of third party OST to PST converter, as it can not only make database accessible but can also facilitate File split alternative. File split feature enables fragmentation of huge files into small files that can be easily stored by the user in desirable file format. OST to PST Converter is one of the OST converter tools that provide file split and file conversion facility along with various recovery and OST file management features. Moreover, execution of such software assures entire file or folder recovery in a secured mode. It is suggested to evaluate the chosen software’s trial version first before making a move to purchase it. So, choose wisely and stay safe.
