Repair PST file after MSMAPI32 DLL error

If you receive an MSMAPI32 DLL error while trying to access your Outlook data, it can be an indication of a corrupted or damaged PST file. You can try the following steps to repair the PST file and resolve the error:

1. Run ScanPST: ScanPST is a built-in tool provided by Microsoft to repair corrupted PST files. To use this tool, close Outlook and search for ScanPST.exe on your computer. Once you locate it, double-click to launch it, select the PST file that is giving you the error, and click on Start to begin the repair process. The tool will scan your PST file and try to repair any errors found.
2. Use a third-party PST repair tool: If ScanPST does not fix the issue, you can try using a third-party PST repair tool like Repair for Outlook . These tools can repair highly corrupted or damaged PST files that cannot be repaired by ScanPST.
3. Create a new Outlook profile: If the issue persists even after using the PST repair tools, it may be due to a corrupt Outlook profile. You can try creating a new Outlook profile and then import the repaired PST file into the new profile.
4. Contact Microsoft support: If none of the above steps work, you can contact Microsoft support for further assistance. They may be able to provide additional troubleshooting steps or suggest other options.

In conclusion, an MSMAPI32 DLL error can indicate a corrupted or damaged PST file. You can try using the built-in ScanPST tool, a third-party PST repair tool, or create a new Outlook profile to resolve the issue. If none of these steps work, contacting Microsoft support may be necessary.
