Why Does the Emsmdb32.dll File Generate these Errors?

Emsmdb32.dll is part of the Microsoft Exchange server module, and this is the reason this file is present in all versions of Outlook. This file is constantly updated by Microsoft as it handles services from MAPI or Messaging Application Programming Interface. MAPI is the messaging architecture which is designed using Microsoft APIs and is used to allow mail clients like Outlook to communicate with Microsoft Exchange.

MAPI provides sessions to these mail clients to open their mailboxes. The problem occurs when multi-threaded programs use a single session of MAPI to log into different mailboxes in Outlook.
