FOCUS ON THE BASICS
Throughout this book, you’ve learned about the features of Microsoft Exchange Server, whose initial release was version 4.0. The newest release, version 5.0, gives Exchange users several new and exciting ways to access their mailboxes on a Microsoft Exchange server and adds the capability to access Internet newsgroups via Exchange Server public folders. Also new are support for connecting to Lotus cc:Mail systems and a number of general enhancements to the Exchange Server client.
NEW FEATURES IN EXCHANGE SERVER 5.0
Exchange Server 5.0 adds three new ways to access your Exchange mailbox.
For users, the biggest news in Exchange Server 5.0 may be the three new clients:
Microsoft Outlook
Internet (POP3) support
Web browser support
Outlook is an entirely new client included with Exchange Server 5.0 that organizes mail and scheduling, plus all sorts of desktop information. It’s also part of Microsoft Office 97. You’ll get an in-depth look in the next chapter.
Exchange Server 5.0 turns the server into a POP3/SMTP mail server, which means you can access your Exchange mailbox from any mail software that can access a POP3 mailbox. That could be Exchange using the Internet Mail service, or it could be a completely different mail program such as Eudora. This change is important if you need quick, reliable access to your mail (but not to public folders) from a machine that might be underpowered for the standard Exchange Server client, or that is running an operating system for which there is no Exchange client.
The third new way to access your mail is via a Web browser that supports frames and Java, such as Microsoft Internet Explorer 3.0 or Netscape Navigator 3.0. You can not only see your mailbox, but also use public folders and search the address list.
Microsoft also has added Internet newsgroup support to Exchange Server, allowing you to read and post messages to newsgroups as you would with other public folders and to publish public folders so they can be accessed by newsgroup client programs.
Another new feature is a connector to Lotus cc:Mail systems, so you don’t need to use a separate Exchange service such as MAPI ConnectorWare for cc:Mail or ccXchg (see “Enterprise Mail Services,” in Chapter 9).
Let’s start our survey of the new features by examining some general enhancements to messages, rules, and folders in the new Exchange Server 5.0 client. Then we’ll look at the cc:Mail, POP3, Web, and newsgroup features.
MESSAGE ENHANCEMENTS
Changes to the message window make it easier to browse items that you haven’t read. Exchange has added a Reply To address for your messages. Also, you can specify either MIME or UUENCODE for any particular recipient in your address book. Finally, you also can now exchange security keys with Exchange Server users at other organizations.
Improved Browsing
When you have an item open, you can easily move to the first item in the next or previous group of items or view the next or previous unread item.
To read the next unread item, choose View, Next Unread or click the Next Unread button.
To read the previous unread item, choose View, Previous Unread or click the Previous Unread button.
To see the first item in the next group of items, choose View, Next Group or click the Next Group button.
To see the first item in the previous group of items, choose View, Previous Group or click the Previous Group button.
New buttons for Next Unread and Next Group are automatically added to the toolbar in the window used to read posts in folders. To add these buttons to the toolbar in the window used to read messages, open a message, then choose Tools, Customize Toolbar. You’ll also need to customize the toolbar if you want to use the Previous Unread or Previous Group buttons for browsing either messages or folder posts.
Supporting “Reply To”
You now have the option of specifying a Reply To address to redirect replies to a different address.
You can now specify that replies to your message be sent to a different address, rather than to your own e-mail address. This feature, called “Reply To,” is often found in Internet mail programs.
To change the Reply To address for a message,
In the New Message window, choose View, Reply To Box.
The Reply To box appears at the top of the New Message form, as shown in Figure 25.1. Either type in the recipient’s name or address, or click the Reply To button to use the Address Book to enter the address.
Like the Bcc box (see “Displaying the Bcc Box,” in Chapter 11), the Reply To box will appear in every New Message window until you disable it by choosing View, Reply To Box again.
If you want both another person and yourself to get replies, enter both your own address and the other person’s in the Reply To box.
Specifying Per-Recipient Encoding
If you use MIME as the default for encoding Internet messages (see “Choosing a Message Format,” in Chapter 22), but a particular recipient needs a different encoding method, you can now associate a specific format in that recipient’s entry in your Personal Address Book. Here’s how:
Choose Tools, Address Book.
Select an Internet recipient, then choose File, Properties.
On the SMTP - Address tab of the Properties dialog box, click the “Send Options…” button to display the “Send Options for this Recipient” dialog box shown in Figure 25.2.
Check the box labeled “I want to specify the format for messages to this recipient.”
Select the format you want to use — MIME (plain text and/or HTML), UUENCODE, or UUENCODE with BINHEX for Macintosh attachments.
Click OK to save the format with the address book entry.
Note that this option works only when you have the Microsoft Exchange Server service in your profile, and does not affect messages sent through other Internet services.
Sending Security Keys
You can exchange security keys with Exchange Server 5.0 users in other organizations, letting you send and recieve encrypted and digitally signed mail.
If you use Exchange Server security (see “Working with Microsoft Exchange Server Security,” in Chapter 21), your public security keys can be exchanged with users in other organizations that also use Exchange Server security. This will let you send and receive encrypted and digitally signed mail via the Internet.
Exchange Server 5.0 includes a special form for creating a message to exchange keys. When the recipient opens the message, it displays the option to add an entry to the Personal Address Book that includes the keys.
To send your keys to another user,
Choose Tools, Options, then switch to the Security tab.
Click the Send Security Keys button.
In the Microsoft Exchange Security Logon dialog box, enter your “Security password,” the one you entered when you set up security for Exchange, then click OK.
In the Security Key Exchange Message window, shown in Figure 25.3, enter the addresses of the Exchange Server users to whom you want to send your keys. You can either type their addresses in the To box or click the To button and pick them from the address book.
Exchange automatically fills in Your E-mail Address with your Internet e-mail address. You should check both that and the Display Name, because these will be used to build a Personal Address Book (PAB) entry on the recipient’s computer.
You can transmit additional information for the PAB entry that will be created. Enter your Company and other details in the boxes at the bottom of the Security Key Exchange Message window. If you leave any box blank, clear the corresponding checkbox.
Click the Send button when you’ve finishing filling out the form.
This message will appear in the recipient’s Inbox with a green key icon and the subject, “Security Keys for” plus the name of the sender. To add the keys contained in the message to the PAB,
Open the message that displays the green key icon.
In the Security Key Exchange Message window, shown in Figure 25.4, use the fields at the bottom of the window to add any personal details that you want to store in the PAB.
Click the Add to Personal Address Book button to create a new PAB entry that includes this person’s security keys. Enter your security password if you’re prompted to do so.
Close the Security Key Exchange Message. You might want to retain a copy of the message in an archive folder in case you ever need to reconstruct that Personal Address Book entry.
Here are a few additional notes about exchanging security keys:
You don’t need to exchange keys with people in your own organization, because they can access your public keys through Exchange Server.
The recipient must be using version 5.0 of the Exchange Server client and must be enabled for Exchange Server security.
When you receive a key exchange message, both you and the sender can use the “Verify key integrity” button to display a series of codes that can be matched over the phone or by some other separate means to confirm the accuracy of the key exchange.
