You run the New-MailboxImportRequest cmdlet to import a .pst file into a mailbox in a Microsoft Exchange Server 2010 environment. In this situation, the Microsoft Exchange Mailbox Replication Service service crashes. Additionally, the following event is logged in the Application log:
Log Name: Application Source: MSExchange Common Event ID: 4999 Task Category: General Level: Error Keywords: Classic Description: Watson report about to be sent for process id: <ID>, with parameters: <paramter>, MSExchangeMailboxReplication, M.Exchange.PST, M.E.P.Attachment..ctor, System.NullReferenceException, c16e, 14.01.0218.005.
This issue occurs because the value of a variable is set to Null. However, there is no check for null variables before the Microsoft Exchange Mailbox Replication Service service accesses the variable.
To resolve this issue, install the following update rollup:
