XCLN: Outlook Message Sent to Wrong Recipients/Offline Address Book Corruption

• Microsoft Outlook Windows 95/98 client, versions 8.0, 8.01, 8.02, 8.03, 8.04, 8.5
• Microsoft Outlook Windows NT client, versions 8.0, 8.01, 8.02, 8.03, 8.04, 8.5

SYMPTOMS

When you compose a message offline using the offline Address Book, the message may be sent to the wrong recipient. For example, User A sends an e-mail message to User B and in the Sent Items folder, the mail may be shown as having been sent to User C. When you check the properties for User C in the Sent Mail folder, they are those of User D.

CAUSE

When a name in a message is resolved from the Global Address List in an offline Address Book, that name coincides with an entry ID in the Global Address List. If address additions or modifications cause new X.500 address information or SMTP domains in the online Address Book, the client offline Address Book information may contain domain name offsets that do not match the server offsets. Thus, the display name is right but the resolution is wrong, resulting in a misrouted message.

RESOLUTION

A combination client/server fix for this issue exists and must be deployed to resolve this issue in the following manner:

1. Install Microsoft Exchange Server 5.5 Service Pack 2 on all the Exchange Server 5.5 computers. The service pack can be downloaded at:




ftp://ftp.microsoft.com/bussys/exchange/exchange-public/fixes/Eng/Exchg5.5/SP2/

2. Quit Outlook.



3. Apply the Archive Patch on each desktop computer. The patch can be downloaded at:

5. Start Outlook.



6. Perform a complete offline Address Book download with full details.
