How to Fix “MAPI was Unable to Load Information Service Msncon.dll” Error Message in Microsoft Outlook?
As we all know Microsoft has released a free Customer Preview build of its upcoming Office suite "Office 2013" to public. I was using Microsoft Office 2010 in Windows 7 and I decided to test this new version of Office. So I uninstalled Office 2010 and also uninstalled Outlook Hotmail Connector which is used to access Hotmail account in Outlook.
After uninstalling previous Office suite, I installed the new Office 2013. Everything was running fast and fine but when I tried to run Microsoft Outlook 2013, I got following error message:
Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. An unexpected error has occurred. MAPI was unable to load the information service msncon.dll. Be sure the service is correctly installed and configured.
No doubt, the error message was not very helpful so I decided to search on Internet. I found a few topics at Microsoft Answers and I found that its a known problem and can occur in almost all Outlook versions such as Outlook 2003, 2007 and 2010. And now the same error message was appearing in latest Outlook 2013 version.
I found that this problem is related to "Microsoft Outlook Hotmail Connector". If you uninstall the connector or a few files or Registry settings of Hotmail Connector get corrupted in Windows, you might face this annoying error message at Outlook startup.
So what's the solution? The solution is to repair "Outlook Hotmail Connector". You can either repair it using "Control Panel -> Programs and Features" (aka Add/Remove Programs) window or run its setup again and it'll repair the connector and you'll be able to start Outlook without any problem.
Fine. This solution will work in previous Outlook versions but "Outlook Hotmail Connector" doesn't support the new Outlook 2013 version. When I tried to run the installer, it showed error message that Outlook Hotmail Connector requires Outlook 2003, 2007 or 2010 versions.
So repairing Outlook Hotmail Connector didn't help in Outlook 2013. Further research revealed that sometimes deleting a file "MSMAPI32.DLL" present in "C:\Program Files\Common Files\System\MSMAPI\1033" folder can also fix this problem. So I tried to delete the file and re-launched Outlook 2013. It took a few seconds and then showed the same error message again. When I checked, the MSMAPI32.DLL was created again by Outlook.
At last I extracted the EXE file of Outlook Hotmail Connector using 7-Zip and I found an MSI file in it. Again I extracted the MSI file and I found a DLL file "MSNCON32.DLL" in it.
Without wasting time, I copied this new DLL file in "C:\Program Files\Common Files\System\MSMAPI\1033" folder. Surprisingly, the trick worked. Now Outlook 2013 didn't show any error message and started without any problem.
So if you also face this error message problem in Microsoft Outlook, do as following:
- Reinstall or repair Outlook Hotmail Connector.
- If it doesn't work, extract the connector setup file and copy the DLL file to above mentioned folder.
