Microsoft Outlook - Error loading msncon.dll file

August 2015

While using MS Outlook for first time,vyou may be unable to launch the software. To enable it, go to "Control Panel > Mail > Email Accounts > Data Files" by changing your default to a local archive file, rather than a MAPI account. But connecting to MAPI (hotmail) account using the connector is not possible for system events as activation context may fail, as msncon32.dll files are not found by the system.
Use sxstrace.exe for detailed diagnosis. Now, in Tools, go to Add-ins and "GO" on 'Manage COM Add-ins', select (checkbox) Hotmail Connector and you get an Admin failed message. Just by selecting the "COM Addin for Microsoft Outlook Hotmail Connector" line, you get a message on the Load Behavior message line - "Not loaded". A runtime error occurred during the loading of the COM add-in. This indicates the admin message is due to load failure rather than an actual admin failure, as you logon as an admin user.
