When accessing the Inbox on Windows Mobile 6 device, by default there will be a prompt to setup a "New E-mail Account". To bypass this and access your NotifyLink messages, you will need to disable the account picker at startup. The option for this can typically be found by using the following steps:

Pocket PCs: (e.g. Treo 750, Sprint Mogul)
1. Go to "Messaging"/"Inbox"
2. Click "Menu" on the right soft-key.
3. Click "Options"
4. Uncheck the box for "Display account picker when opening Inbox"

Smartphones: (e.g. T-Mobile Dash)

2. Go to "Text Messaging"
3. Press the right navigation key until the "Outlook E-mail" folder is displayed.
4. Click "Menu"
5. Click "Tools"
