In a collaborative messaging environment with Microsoft Exchange Server, you can use email organizer tools to effectively manage your emails. The email organizer tools are installed on the client system and by using then you can organize your PST (Personal Storage) files, IMAP (Internet Messaging Access Protocol) folders and Mailboxes. These programs are also used for synchronizing the OST (Offline Storage) file with Microsoft Exchange Server database and download newly received emails from the server. But in some situations, while synchronizing the OST file with Exchange Server, several errors occur and the OST file can not be converted into PST. In such cases, to access data from the OST file, you need to manually Convert OST to PST using third party tools.
As a practical case, the MAPI errors might occur in Exchange Server Synchronization Log during fast (ICS) for full synchronization with Microsoft Outlook. This errors is usually reported as “Unspecified Error” and in some situations, it is associated with few MAPI error codes like 80040115 or 80040119.
Root of the issue
This problem generally occurs due to corruption to the Exchange Server mailbox or user profile. Due to corruption, the connection between Exchange Server database and OST file can not be established.
An exact copy of Microsoft Exchange Server mailbox is stored on the user system (client hard drive) in the form of OST file. When you connect with Exchange Server, the OST file is synchronized with Exchange Server mailbox and automatically gets converted into PST. In this case, the OST file can not be converted and thus it can not be used to access data from Exchange Server.
Resolution
To work around this issue, you are required to recreate the Exchange Server user profile. To do so, you need to have administrator privileges to log into Exchange Server. After recreating the profile, you have to manually Convert OST File into PST to use it with Exchange Server profile. The conversion is best possible with the help of OST Repair Tool.
