Many organizations or enterprises prefer Microsoft Outlook to exchange the information over emails as Outlook is well known for data security and reliability. Outlook stores all its mailbox data in PST (Personal Storage Table) file format. In contrast the Exchange server generates an OST (Offline Storage Table) file instead of PST to save the mailbox items. OST files are the offline files on which users can work easily and the changes will get automatically saved once the internet connectivity is re-established. These OST and PST files not only store emails but the other mailbox items as well. So it becomes quite difficult for users to access the Outlook data file if the OST and PST file size increases beyond the limit. There might be a risk of corruption that can lead to severe data loss as well. Users have queries about “how to reduce Outlook data file size”. In this blog, we will discuss the most recommended methods to reduce Outlook mailbox size. We will provide the manual techniques and OST splitter professional software to split the oversized OST files.
Outlook sometimes uses a conflict folder to store the conflicted items in it. When a copy of an item is saved on the email server and is not synchronized with the copy of the item stored in the local computer then, conflicts take place. Outlook Mailbox cleanup tool can delete the conflicts for the user.
OST files are the offline storage files supported by MS Exchange to save the mailbox database. OST files are similar to PST files with an exception that one cannot import or export from the offline Outlook data file. Now follow the steps to compress OST file manually.
When your Outlook PST file becomes oversized and exceeds the mailbox size limit then, it affects the performance. Also there is a risk of corruption and ultimately a risk of severe data loss. In this scenario, the user needs to compress the PST file. How to reduce PST file size? Well, you just need to follow the manual steps provided for manual compression.
Note: These are the manual steps and sometimes manual strategies are more time consuming and complex and would not work properly. As an alternative, users can also opt for the professional advanced techniques available to split the large Outlook data files without any hassle or worry.
