We've had a number of complaints since the release of Outlook 2010, where a few emails are corrupted, with the header belonging to one message and the body is from a second message. The messages are fine on the server and the problem is with Outlook. This bug was documented in An email message body contains text that is added from previously opened email messages when you access a mailbox by using an IMAP4 client in Outlook 2010 (MSKB).
The users who are affected by this bug may see one or more of the following issues:
- The body from one email message is displayed in the body of another email message.
- Text from an attachment in one email message is displayed as garbage text in another message.
- Some content in an email message is not displayed.
- The body of an email message is displayed as unconverted MIME text.
Along with the problem of merged messages, this hotfix also fixes other IMAP problems, including a problem when email messages that are forwarded automatically using an IMPA4 email account have a blank body.
If you are one of the unlucky persons with this problem, install the February hotfix.
Other issues the hotfix addresses
This hotfix addresses a long list of issues, including the following:
- Another blank body issue is fixed, this time for Exchange server mailbox users. When you use online mode and lose (and regain) network access while composing a message, a blank message is sent. Note that this fix works only for messages that do not have an attachment. If you lose network access while composing a message with an attachment, you'll need to recreate the message while online
- When you are working in online mode and try to open a public folder while the Exchange server is disconnected, Outlook 2010 tries continuously to connect to another server.
- When you disable the Use Cached Exchange Mode for new and existing Outlook profiles option in the Office Customization Tool or in Group Policy, the profile uses Cached mode unexpectedly.
- When you change the display name of a .pst file in a profile then remove and re-add the .pst file, the display name of the profile is changed to the .pst file name.
