Q: I get this error: HrFindCDOTimezone:Warning:CDO Session timezone exceeds known index - Ignoring. What does this mean? Thanks.
A: The CDO timezone information on a mailbox is set by CDO applications that connect to Exchange (such as Blackberry).  In some cases an application may set a value that the tool does not recognize, and this message indicates that because we do not recognize the value, we are ignoring it and proceeding with processing the other values.
