Microsoft Outlook 2007/2010/2013 RSS Subscription Format | Microsoft | Settings Files |
The OBI file extension, associated with Microsoft Outlook, is used for saving RSS (Really Simple Syndication) subscriptions in an Outlook folder. These files act as pointers to an RSS Feed URL and store it separately from the users main subscription file, allowing a user to keep track of their subscription to various blogs or other web content. By default, these OBI files are created in the 'My Feeds' folder and their initial name contains the name of the RSS feed.
File Details And Creation
An OBI file contains very little information other than the location of the corresponding RSS feed. This typically includes an up-to-date address, access tokens needed for the server, protocol used to connect, version of protocol, other data associated with the feed such as password or timeout information. An OBI file can be created in Microsoft Outlook by subscribing to an RSS Feed from within 'My Feeds' folder under 'RSS Subscriptions'. Files in this format can be opened by right-clicking the file and selecting "Open with Internet Explorer". This will refer to Microsoft's browser.
Similar File Extensions
Similar files extensions related to OBI include .RSS, .OPML, .XML, and .HTML.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .OBI) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .OBI extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .OBI file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .OBI extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .OBI extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .OBI file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .OBI file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .OBI file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .OBI file) will be extended to the maximum.
It is also good to check
- if the .OBI file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
