JSI Tip 1355. SBS client: Outlook does not recognize your mailbox name.

When an SBS client opens Outlook for the first time, they may be greeted with:

Microsoft Outlook does not recognize: <mailbox name>

There is a bug in SBS that causes this behavior when you have multiple users with similar logon names.

To workaround the problem:

1. Select the correct name in the list of displayed mailbox names.

2. Click OK.

Outlook will now remember the correct mailbox name.
