Outlook Error Message: "Could not open one or more attachments."

July 05, 2006



Summary

Outlook reports "Could Not Open One or More Attachments" when double clicking a message that contains an attachment. The symptoms also occur while using a different profile, Outlook Client or computer while opening the same attachment. This does not occur for all attachments but random users, senders and attachment types. Attachment types are valid and not blocked ie. .pdf, .xls.

Cause:

In this instance, Groupshield AV, may have played a role by some how locking messages in the attachment table within the Exchange Store.

Solution:

1. Open Services.msc. Restart Groupshield for Exchange. (If not using Groupsheild, stop your Exchange aware AV application.)
2. Restart Exchange store, this should unlock the attachment within the Exchange store.

Applies To:
Outlook 2000, 2003
Exchange 2000, 2003
