This feature may also be able to repair corrupt e-mail messages that can cause issues. Use the following steps to Detect and Repair Microsoft Outlook:

- Open Outlook.
- Click the Help menu, then click Detect and Repair. The Detect and Repair dialog appears.
- Enable the Discard my customized settings and restore default settings option, then click Start. You may be prompted to insert the Microsoft Office Installation CD.
Note: Checking this option will clear your custom settings and options in Outlook. Do not check this box if you wish to retain these settings. - Once the Detect and Repair is complete, restart your computer.

SCANPST.EXE - The Outlook Inbox Repair Tool:
The Microsoft Outlook data file that stores e-mail messages is the Personal Folders (.pst) file. The Personal Folders (.pst) file can be assigned to be the default delivery location for e-mail messages or you can use a Personal Folders (.pst) file to back up or organize e-mail messages.
If ACT! is not able to open the Personal Folders (.pst) file, or you suspect that this data file is damaged, you can use the SCANPST.EXE file to diagnose and repair errors. If your mailbox is located on a Microsoft Exchange Server, it is not necessary to run this executable file to repair your Inbox.
The Inbox Repair tool is installed when you install Microsoft Outlook and works on both the Microsoft Outlook Personal Folders File (.pst) and the Outlook Personal Folders File (.pst) data files.

Creating a New Outlook Profile:
Outlook uses Profiles to store e-mail account information (including where your e-mail is stored). A Profile is created the first time Outlook is opened. Most users only need one Profile. However, you may find it to your advantage to create more than one Profile; if (for example) you need a personal e-mail account that is different from your work e-mail account. If you share your computer with other users, their e-mail accounts and settings can be kept in a separate Profile.
For additional information regarding Outlook Profiles, click the following link:
Note: The following information is provided as a convenience. Sage does not provide support for Microsoft Products. For more information on this topic go to Microsoft.com
Before creating a new profile it is highly recommended that you back up your current Personal folders (.PST) file. for more information, please refer to the following Microsoft Knowledge Base document:
