What are MAPIProxy32.dll Error Messages?


Dynamic Link Library MAPIProxy32.dll Errors

MAPIProxy32.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like MAPIProxy32.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. BlackBerry Desktop Manager) could share the same MAPIProxy32.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when MAPIProxy32.dll is attempted to be loaded either when BlackBerry Desktop Manager is starting up, or in some cases already running. Some of the most common MAPIProxy32.dll errors include:

Your MAPIProxy32.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with BlackBerry Desktop Manager), or deleted by a malware infection. Furthermore, MAPIProxy32.dll file corruption could be caused from a power outage when loading BlackBerry Desktop Manager, system crash while loading MAPIProxy32.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix MAPIProxy32.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your MAPIProxy32.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many MAPIProxy32.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the MAPIProxy32.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your MAPIProxy32.dll File (Caution: Advanced)

    Windows 10: C:\Program Files (x86)\Common Files\Research In Motion\AppLoader\
  4. Restart your computer.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve MAPIProxy32.dll problems.

Download MAPIProxy32.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying MAPIProxy32.dll to your appropriate Windows system directory. BlackBerry typically does not release BlackBerry Desktop Manager DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing MAPIProxy32.dll and all other DLL files for BlackBerry Desktop Manager. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
