Troubleshooting Problems Opening EDB Files

Issues Opening EDB Files

Microsoft Exchange Server Not Present

You encounter an error message such as "%%os%% Can't Open EDB Files" when trying to open your EDB. If this is the case, it's usually due to the fact that you do not have Microsoft Exchange Server for %%os%% installed on your computer. This will prevent you from double-clicking to open the EDB file because the OS doesn’t know how to handle it.

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

Obsolete Version of Microsoft Exchange Server

In some cases, you might have a newer (or older) version of a Exchange Information Store Database file that is unsupported by your installed application version. Installing the latest version of Microsoft Exchange Server from Microsoft Corporation is recommended. The primary cause of this problem is that your Exchange Information Store Database file was created by a different (newer) version of Microsoft Exchange Server than what's installed.

Tip: If you right-click on your EDB file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Ultimately, most of the difficulties opening EDB files are due to having the wrong version of Microsoft Exchange Server installed.

Other Causes of EDB File Opening Problems

Assuming you have the right Microsoft Exchange Server version installed, other problems can prevent you from opening EDB files. If you are still having problems opening EDB files, there may be other issues that are preventing you from opening these files. Additional factors include:

• EDB file references in the Windows Registry are broken
• Corruption of the EDB file description inside the Registry
• Microsoft Exchange Server or another EDB application experienced a flawed installation
• EDB file corruption
• Past or present virus infection has affected your EDB
• Hardware related to EDBs has device driver corruption
• Windows has inadequate resources to open your Exchange Information Store Database file
