Multiple Exchange accounts in Outlook 2010

We have recently deployed some new machines to users, who are using Windows 7 and MS Office 2010.
Here are a couple of tips that I came across for Outlook 2010 that are different from its previous versions.

In order to create multiple exchange accounts in the past I have had to use different profiles, although MS Outlook 2010 can be configured in the following way:
Outlook 2010 supports connecting to as many as three Exchange accounts from a single profile, here is how to do it.
Windows Vista or 7: type “Mail” into the search box in the control panel to find the Mail Applet.
In Windows XP the applet is shown in the default Control Panel view.
Once you’ve launched the Mail Applet choose “E-mail Accounts…” and then “New…” From there, the wizard will allow you to add another Exchange account.
Are there any caveats or drawbacks?
Your additional Exchange accounts function just like your first Exchange account in almost every way. Some things, however, are different. For example, the To-Do Bar shows appointments only from your default store, not those from additional Exchange account calendars. To view which store is your default click the Office button, then Account Setting, then, choose the Data Files tab.
What else is improved about Multiple Accounts?
The Ribbon in Outlook 2010 is specific to the account at which you are looking. If you click New E-mail in the ribbon while looking at the Inbox of your second Exchange account, your new message will be sent from your second Exchange account.
Sending from multiple accounts:
When you add a second account of any type to Outlook 2010, the new From Picker will show up on new mail messages. This allows you to easily see which account you’re sending from, and just as easily change it. These are just some of the improvements we made to help you manage multiple accounts in Outlook 2010!
