The Microsoft Exchange Information Store service crashes on an Exchange Server 2007 that has the mailbox server role installed. Additionally, the following error message is logged:
Event Type: Error Event Source: MSExchange Common Event Category: General Event ID: 4999 Description: Watson report about to be sent to dw20.exe for process id: 7336, with parameters: E12N, c-rtl-AMD64, <version>, store.exe, mdbrest.dll, 4e0f0, c0000005, d33a, <version>.

This issue occurs because a meeting request contains an extremely large attendee address or display name. When the meeting request is opened in Microsoft Office Outlook or in OWA, the Exchange Collaboration Data Objects (EXCDO) component helps to process iCalendar object. However, EXCDO does not have a restriction for the address length or for name length. This causes the crash.
To resolve this problem, install Update Rollup 8 for Exchange 2007 Service Pack 1. For more information about Update Rollup 8 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
