Ecommunicator N O R T H W E S T E R N U N I V E R S I T Y I N F O R M A T I O N T E C H N O L O G Y SPRING 2 0 0 5 N O. 2 ecommunicaFor staff and faculty interested in using technology that impactstor their work environment. Get Ready for a Leaner, Cleaner Inbox with Northwestern’s New E-mail Defense System If your DELETE key is getting a daily workout from the mountain of unsolicited commercial or junk e-mail, take heart. Soon, your inbox will be lighter and healthier as those annoying “need a 3.25% mortgage rate,” “this pill will fix everything,” or “take your business worldwide” messages begin to disappear. The reason: Northwestern’s new University-wide E-mail Defense System (EDS). The E-mail Defense System is an enterprise e-mail filtering system powered by Sophos PureMessage. It will scan all incoming Northwestern e-mail for junk e-mail, virus, and malicious spyware threats before they are delivered to the University’s central e-mail servers (casbah, hecky, lulu, and merle). How will the E-mail Defense System work? Using a combination of anti-virus, anti-junk e-mail and threat reduction technology, each incoming e-mail is analyzed and assigned a junk e-mail probability rating between 0% and 100%. The higher the rating, the more likely the e-mail is identified as junk and is safely quarantined in a separate location on the network. Each user will receive a daily e-mail digest with a list of quarantined messages and will have the opportunity to access, review, and retrieve any messages falsely identified as junk. Users also have the benefit of managing their quarantined messages, ensuring that desired e-mails are properly delivered. Most importantly, virus-infected e-mail is now automatically blocked, posing no threat to the network or individual computer systems. How did Northwestern choose this system? An evaluation team with University-wide representation was involved in testing the new system. Benchmarking also took place with several peer institutions, such as the University of Chicago and Purdue University, who are currently using this technology with great What’s Inside! success. Electronic Encyclopedia..........page 2 “It was important for us in the testing phase to identify and address University-wide Datacenter Upgrade...........page 2 priorities relating to the new E-mail Defense System,” said Wendy Woodward, director of NUIT Technology Support Services. “The end results were overwhelmingly high.

  • Calendar Quick Start Using Outlook Web Application (OWA) 1 Signing
    Calendar Quick Start using Outlook Web Application (OWA) Signing In • Point your browser to: email.fhda.edu 1 • Select either private or public computer. If you are the only person who has access to the computer it is private. With the private version, the system will allow a longer period of inactivity before signing you out. • Leave the box next to “User light version…” unchecked unless you are visually impaired or are using a very old version of your browser. • Enter you 8-digit Campus Wide ID (CWID) and the password you use to sign into MyPortal. Some basics: 1. E-mail and calendar are completely integrated. A meeting invitation will generate an e- mail that appears in your inbox and displays on your calendar. 2. Right clicking (Control click on a Mac) will often display a menu that contains the action you are looking for. 3. Moving your mouse over an icon will display the icon’s function. 4. Icons without a down-arrow next to them do only one thing. There is no drop-down menu. 5. Clicking on an icon or title can produce something different than when you click on the down arrow next to it. For example clicking on New in the menu bar will bring up the form to create a new e-mail. However clicking on the down arrow to its right will display a list of options. 6. Arrows pointing to the right are used to expand and collapse lists. In the example to the right, the solid arrow shows that Ann Beebe’s list of files is expanded, but the Inbox folder is collapsed.

Makes it difficult to send something that you think we will see. Find this with external more than email. Webmail and Eudora client versus looking at home. Get rid of spam, go home, and it’s all there again. They reverted back to old webmail version and I lost everything. Webmail the weakest point. I find Cyrus pretty good. Server-side mail features pretty good. Mail can be filtered into folders, don’t have to duplicate into folders, but haven’t rolled out campus-wide. This is an absolute essential, that’s client independent (device and software). Automatic contact lists. Should be able to go to like a division and have their emails loaded into your contacts. And be notified that people left Stanford. It affects the length of my contact list. Ex.: Peoplesoft indicates that they are gone and no longer at this email. Should interface with PeopleSoft. We recognize the corporations don’t have to standardize; they support choice. We work with administrative guidance stuff. Per the admin guide and request of president’s office.

Behind the Scenes: Bringing University Administrative Systems to Life! Have you ever watched the credits roll at the end of a movie? It’s amazing to see how many people it takes to create a blockbuster production. Everyone on the film crew has different jobs, working “behind the scenes” for the same goal . to bring the project to life! Minus the Hollywood glitz, Northwestern’s Information Technology Management Systems (ITMS) team works in much the same way—behind the scenes every day to keep essential University administrative systems running smoothly. If your job involves accessing functions such as payroll, job tracking, registration, or student accounts, or you have enjoyed the convenience of being able to update your directory information, view your paycheck, or review your benefits online, then you are being supported by Management Systems. “We think of ourselves as part of a much larger team within Northwestern,” said Betty Brugger, director of Management Systems. “Collaboration with other departments is essential. The varied talents, skills and interests of those we partner with help us to achieve optimal results.” Major Blockbuster Releases Management Systems’ primary customers are central administrative offices and administrative units of schools and divisions. Among the major initiatives Management Systems has helped develop and maintain for the University are the Human Resources Information System (HRIS), Electronic Time Entry System (ETES), and Student Enterprise System (SES).

  • Proposal for Aventri Intelligent Meeting & Event Management Software
    13 Marshall St. Norwalk CT 06854 www.aventri.com MEETING AND EVENT MANAGEMENT SOFTWARE OVERVIEW Prepared by Kathleen Roberge Chief Revenue Officer, Aventri PROPOSAL OUR VALUE PROPOSITION The unique offering and opportunities from Aventri help reduce total cost of ownership (TCO) and enable future growth. These two points and more have been outlined and considered extensively through each part of this proposal. A fundamental question we would pose in helping you decide would be this: would you prefer a partner that has dedicated the majority of its resources to creating, developing and seeking perfection for its product, or a partner that’s reasonably content with its product and pours all its money and resources into marketing and promoting it? Now there’s nothing wrong with marketing, but it doesn’t help Aventri successfully improve the quality of its meetings program or end-to-end event management activities. Our obsession with product perfection means we are working every day to enhance our product and have our customer base share in the results. It is this mindset that allowed us to record a 90+% renewal rate and maintain lasting relationships with organizations like Dell, Amway, Aveda, Colombia University, and The Financial Times, to name a few. It is this same mindset that pushes Aventri to constantly seek added functionality to our already- robust system. We introduce new features every two weeks to ensure the platform is constantly evolving and these updates are available instantly to our clients as part of their subscription. We bring our expertise as former event planners and event strategists to the table and offer our expertise to help you realize your vision and enable future growth.

  • Using Skype for Business for Virtual Office Hours
    Using Skype for Business for Virtual Office Hours Skype for Business is a communications platform that allows you to interact with your colleagues and students using instant messaging (IM), audio and video conversations, and Skype for Business Meetings. It runs on Windows and Mac operating systems, mobile devices and the web. The web application has limited setup options that prevent you from restricting access and recording your meetings. It is prudent to restrict access to your virtual room to avoid interruptions if you are discussing an issue with a student, and you do not have to worry about students using the room as a group chat when you are not present. Therefore, you should use the desktop version because the meeting options are more robust and stable, and you have the option to record your office hours. Scenarios There are a variety of scenarios for creating a Skype online meeting using the Outlook client (Outlook on your desktop) and Outlook for web and entering the meeting room using the Skype for Business client and the Skype for Business web application. 1. You can create Skype online meetings using both platforms for Outlook (web and desktop) 2. You only have a full set of meeting options when you create an online meeting using the Outlook client. Meeting options are limited if you create a Skype online meeting from the web application. 3. You can generate a link to the online meeting room without saving or adding attendees in both platforms. However, if you want to save the meeting, you must add yourself as an attendee in the client.
