Configuring Microsoft Exchange Online (Office 365 Email)


This information is relevant for Whiting School of Engineering users only.

If you found this page through a search and are from a different part of Johns Hopkins, you should refer to your local IT support staff for your correct information.  Following these instructions could cause you to lose mail and might cause your computer to catch fire.  You have been warned.

Webmail

The web client for your mailbox can be found in MyJH (under Messaging -> Outlook). It also can be accessed directly at http://outlook.com/jh.edu.  Webmail is a great diagnostic tool because it requires no client configuration and shows you directly, exactly what is on the mail server.  If something isn’t working right, or you can’t find something, checking that your webmail is working correctly is a perfect first step.

Email Client Settings

Most users should use the native Exchange protocols for mail and calendar when connecting to Microsoft Exchange Online, just like they did before Summer 2019.   This is the native connection type for Outlook, and is supported in many third-party tools like the Mail and Calendar tools that come with MacOS.

For Linux users, or people who prefer older clients like Thunderbird, IMAP, POP, and SMTP are enabled by default for all mailboxes on Office 365 — there is no longer a need to get prior approval to use those mail protocols.

Authentication is required for all protocols.

Username for all protocols JHED@jh.edu (ex: jdoe5@jh.edu)
Password JHED password (ex: C0mpl1catedP@$$word)

 

Protocol Server Address Port Authentication
Exchange Activesync (preferred, when available) Should autodetect, but if not:
outlook.office365.com
N/A  N/A
IMAP4 outlook.office365.com 993 SSL / NONE
SMTP smtp.office365.com 587 StartTLS / LOGIN
POP3 (discouraged, only use when other options are unavailable) outlook.office365.com 995 SSL

HOW TO Configure Outlook Mail Client

Outlook 2016 on both Mac and Windows will fairly reliably automatically configure itself for use with the Johns Hopkins mail system AS LONG AS THE CORRECT USER NAME IS USED.  For people migrating from the older Exchange servers they might need to update the username in their client.

When using Outlook with Exchange online, it’s critical to use the username JHED@jh.edu.

WORKS WORKING SAMPLE WILL NOT WORK WILL NOT WORK SAMPLE
JHED@jh.edu smethen1@jh.edu WIN\JHED WIN\smethen1
JHED@win.ad.jhu.edu smethen1@win.ad.jhu.edu
ALIAS@jhu.edu Steve.Metheny@jhu.edu

So, if you see a warning dialog in Outlook similar to this when connecting to Outlook

you should enter your credentials like this

 

In this example, Steve.Metheny@jhu.edu is the alias, and smethen1@jh.edu is the correct login name.

 

 

HOW TO Configure Mac and iOS Mail Client

We find it frustrating to configure Mac and iOS Mail for the O365 mail servers.  To be clear: we’re only talking about the Apple programs that come with MacOS and iOS… the Exchange client on the Mac is more straightforward.  It’s easy to get on the wrong path and not be able to get back.  Here’s how to make the configuration.  Versions of the mail and calendar tools change with each MacOS and iOS release.  These were made on MacOS 10.14, but the process is the same on iOS and should be the same in future releases.  In these screens, esoffro1@jh.edu is the users JHED@jh.edu, and ernie.s@jhu.edu is the user’s email alias.

The steps are a little different depending on if this is a new configuration or if you are just changing your password.

 

Version One: Password Changed (Skip if you’re doing first configuration)

When your password is changed you’ll get an alert that you need to update your password configuration in Internet Accounts.  You’ll see an alert similar to this, or will see that your mail has an alert triangle next to it in the client.

When prompted to enter your password you need to choose Sign in with another account despite the fact that this is a Work / School account.

 

After Sign in with another account has been picked, you’ll get the chance to enter your JHED@jh.edu, which will let Microsoft know that you need to log in using your Johns Hopkins JHED username and password.

 

 

At this point, you’ll get the familiar blue Hopkins login screen.  Log in here with JHED and password as on any other Hopkins system.

Version Two:New Configuration

Start by going to the Apple menu and then to System Preferences.  Pick Internet Accounts.

We want to add an Exchange-style account.

When prompted, enter your real (display) name and email alias.  This is the friendly return address you desire to use on email you send.

Now you’ll want to Sign In to your account using Microsoft.

 

When prompted to enter your password you need to choose Sign in with another account despite the fact that this is a Work / School account.

 

After Sign in with another account has been picked, you’ll get the chance to enter your JHED@jh.edu, which will let Microsoft know that you need to log in using your Johns Hopkins JHED username and password.

 

 

At this point, you’ll get the familiar blue Hopkins login screen.  Log in here with JHED and password as on any other Hopkins system.
