What is a .OSS file?
The file extension .OSS is associated with a Microsoft Outlook Saved Search File. This type of file is created by Microsoft Outlook, which is an email and calendar management program included in the Microsoft Office suite. An .OSS file contains specific search criteria that are used to filter and organize emails into what are called virtual folders. These virtual folders are not actual folders that store emails; instead, they dynamically display emails that meet the search criteria specified in the .OSS file.
For example, if you frequently search for emails from a particular sender or about a specific topic, you can save these search parameters in an .OSS file. Whenever you open this saved search file in Outlook, it automatically filters and shows emails that match these parameters without physically moving or copying the emails into a separate folder. This feature is particularly useful for managing large volumes of email and keeping your inbox organized without duplicating messages.
To open an .OSS file, you need to use Microsoft Outlook 365. In Outlook, you can access or import the .OSS file to activate the saved search, which will then display all emails that fit the search criteria as a virtual folder. This method is an efficient way to handle emails and can serve as an alternative to manually sorting or copying messages into different folders.
