The Exchange Information Store service may crash on an Exchange Server 2007 server. Additionally, the following events are logged when the problem occurs:

This issue occurs when an Entourage client synchronizes with an Exchange 2007 server for an iCalendar item. However, the time zone offsets of the iCalendar item use only 3 digits (such as -400) instead of 4 digits (such as -0400). This does not follow RFC 2445. The Exchange 2007 server does not handle this type of exception well during the conversion that results in the problem.
To resolve this problem, install Update Rollup 7 for Exchange 2007 Service Pack 1. For more information about Update Rollup 7 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
