项目

The scenario is that you are logged into a Exchange 2010 mailbox and want to access a shared calendar or mailbox on Exchange 2007.

When attempting to open the mailbox, you may receive the following error/ (full call stack below):

Exception

Exception type:
Microsoft.Exchange.Data.Storage.StoragePermanentException

Exception message: Cannot open mailbox /o=Company/ou=Administrative Group/cn=Recipients/cn=testuser1.

First, we want to look at the Exception that failed inside of the callstack.

In the Inner Exception:

Exception type: Microsoft.Mapi.MapiExceptionCallFailed

Exception message: MapiExceptionCallFailed: Unable to make
connection to the server. (hr=0x80004005, ec=2084) Diagnostic context: Lid:

80004005 = Generic Error (MAPI_E_CALL_FAILED)
2084 = ERROR_DS_CANT_REM_MISSING_ATT (An attribute cannot be retrieved from AD for the logon)

In troubleshooting the issue, we were able to figure out that the attribute that was missing was SharedCalendarTimezoneSetting.

Background:

There was new functionality that was added to Exchange 2007 SP3 RU1. This new functionality forces Exchange 2007 to check the delegate user's SharedCalendarTimeZone, which is used to determine what time zone to show the mailbox in. This works fine against an Exchange 2007 delegate mailboxes, but unfortunately it doesn’t work against Exchange 2010 mailboxes. The failure happens when the Exchange 2010 user attempts to access the Exchange 2007 mailbox and on login, we attempt to check this value in an attempt to learn how to present the data. This data doesn't exist and therefore the error is generated.

Resolution:

On Exchange 2007, set the default time zone setting:

set-organizationalconfig -sharecalendartimezonesetting principal

Note: This can be set to principal or delegate as the article explains, either will resolve the issue if we are running into this problem.

If the parameter value is set to Principal, the time zone is shown in the principal’s time zone. If the parameter value is set to Delegate, the time zone is shown in the Delegate’s time zone.
