Exchange Server 2003

During August, 2005, I&IT switched to the 2003 Exchange Server. This program is a mail server; it resides on a cluster of computers and receives and transfers email through Microsoft Outlook, a web application called Outlook Web Access, or another email program such as Thunderbird or Entourage. Here is an overview of the new features Exchange 2003 offers to faculty and staff:

Cached Exchange Mode

When an Outlook account is configured to use Cached Exchange Mode, Outlook works from a local copy of a user's Exchange mailbox stored in an Offline Folder file (OST file) on the user's computer, along with the Offline Address Book (OAB). The cached mailbox and OAB are updated periodically from the Exchange server. This means that Outlook no longer depends on a continuous network connection to access user information, and that mailboxes are kept up to date, so if a user is disconnected the information is available offline immediately. It also makes the switch from connection speeds more seamless. If a user is connected to a high speed network connection and then switches to dial-up, Outlook automatically reconfigures to make the transition work smoothly. Note that depending on the size of user’s mailbox Cached Exchange Mode may take a while to synch when first set.

Many current users of Outlook 2003 may already have Cached Exchange Mode set, since it is required for the Outlook spam filter. For best results, it should be turned off when the switch to the new server occurs, and turned back on later.

Outlook Web Access


Outlook Web Access (OWA) is the most improved feature of the new Exchange Server. When using Internet Explorer 5.01 and above, users will see that it has become nearly comparable to Microsoft Outlook 2003 (the email program that comes with Microsoft Office 2003), both in style and capability. The new features include:

New Appearance

Tasks

Rules

Spell Checking

Signature

Inbox Navigation

Calendar Improvements

Spam Protection

ActiveSync

Exchange ActiveSync allows devices such as a browser-enabled cell phone or a Microsoft Windows Mobile–based device to access information on the server. It enables mobile users to gain access to their e-mail, calendar and contacts and retain access to this information while offline. Use of the different features depends on your mobile provider and phone capabilities.

Migration Information

Possible Migration Problems

Q: I cannot connect to a Public Folder

A: Restart Outlook. If that doesn’t work logoff and restart your computer, then open Outlook and try again.

Q: I cannot sign into Exchange via Outlook

A: You may get this error if you left your Outlook window open overnight and your mailbox was moved to the new server. Close and reopen Outlook.

Q: I cannot connect to another user’s calendar even though I have connected to it in the past

A: This may happen if your mailbox was moved and you haven’t restarted Outlook. Restart Outlook and try again. If you still can’t connect recreate the shortcut to the other calendar: File / Open / Other user's folder / Calendar.

Q: I cannot recover my deleted items

A: Once your mailbox has been moved it wipes the deleted files from your mailbox so you will no longer be able to access them. You will only be able to access files that were deleted after your mailbox was moved. Note: This does not affect items in the "Deleted Items" folder, only items that are actually deleted.

Q: I see all my old email in Outlook, but none of the email that has arrived since the server change.

A: If the new email shows up in Outlook Web Access (and you're seeing its new interface, indicating that you are on the new server), this is probably because you had Outlook 2003 set to Cached Exchange Mode – Outlook is confused by the cached files and is still looking on the old server. Here are the steps for fixing it:

  1. In Outlook, select Tools / Email Accounts from the menu. Select "View or change existing email accounts" from the dialog and click Next.
  2. Select the default server (you will likely only have one server) and click Change.
  3. Uncheck "Use Cached Exchange Mode." Then click Next. (If it was not checked, this is not your problem, and you should click Cancel and contact the Help Desk.)
  4. Click OK, then click Finish and close Outlook.
  5. Restart Outlook and it should find your new mail.
  6. Once you have been moved to the new server, you can recheck the box to use Cached Exchange Mode, but in two weeks the problem will occur again when the final move is made. So it is recommended that you leave the box unchecked and don’t use that feature until the transfer to the new server is complete. (You can set a reminder in your Outlook calendar for August 31 to restore Cached Exchange Mode.)
