Understanding OR3 Issues

Typical OR3 Opening Challenges

IBM Lotus Organizer Removed

You encounter an error message such as "%%os%% Can't Open OR3 Files" when trying to open your OR3. Generally, this is experienced in %%os%% because IBM Lotus Organizer isn't installed on your PC. This will prevent you from double-clicking to open the OR3 file because the OS doesn’t know how to handle it.

Tip: When you have another program installed that you know will open your OR3, you can select it from the other programs listed (see "Show Apps").

Outdated IBM Lotus Organizer

Sometimes your installed version of IBM Lotus Organizer won't support your IBM Lotus Organizer 97 File file. Visit the IBM website to download (or purchase) the latest version of IBM Lotus Organizer. Your IBM Lotus Organizer 97 File file was probably created by a newer release of IBM Lotus Organizer than what's currently installed your computer.

Tip: You can sometimes get hints about the right program version by right-clicking on the OR3 file, selecting "Properties", and looking at the version information.

Conclusion: The majority of OR3 file opening issues are due to not having the correct IBM Lotus Organizer version installed.
