Known issues and changes for the implementation of Exchange 2013 at IU

Issue Description Status Last updated
Unable to access OWA from private browser windows in Firefox

After authenticating to OWA (mail.iu.edu) from a private browser window in Firefox, you will receive a message that "an error occurred." The problem was introduced in Firefox version 59.

Other browsers are not affected, and it is possible to access OWA from normal Firefox browser windows.

Expected behavior March 16, 2018
Unable to access options page from OWA

When you follow a link to OWA (mail.iu.edu) from another page and select Options, you may get an error that requires you to close the tab/window to get out of OWA.

To resolve this issue, go directly to mail.iu.edu, rather than getting to OWA from one.iu.edu, a campus homepage, or any site that is not mail.iu.edu.

Expected behavior November 2, 2017
Some users cannot access their Exchange mailboxes via desktop or mobile clients; OWA displays the error "HTTP 400 - Bad Request (Request Header too long)". This can occur if you are a member of many Active Directory user groups (approximately 120 primary groups, or 1,015 primary and nested groups). To resolve the issue, reduce the number of AD groups in which you are a member. For more, see Problems with Kerberos authentication when a user belongs to many groups in Microsoft's online support documentation. Expected behavior June 16, 2017
Some file attachments cause email delivery to fail. Certain file attachments will cause email delivery to fail and you'll receive a bounced email message with the error "Remote Server returned '554 5.6.0 Invalid message content'". Certain file attachments have embedded objects that are incompatible with the Exchange 2013 email security file scanning mechanism. Types of files that may cause this issue include, but are not limited to, some PDFs and Excel spreadsheets. Workarounds include zipping and password protecting the file before attaching it, or using an alternative service like Box or Slashtmp. Known issue October 16, 2015
In Conversations view, OWA does not provide preview text or a Reading Pane view for any digitally signed (S/MIME) email message. If you use Conversations view in OWA, preview text and Reading Pane view are not available for digitally signed (S/MIME) email. To read a digitally signed message, you must open it in a new window. Turning off Conversations view enables normal preview and Reading Pane functionality for S/MIME messages. You can enable preview text in Conversations view by installing the Microsoft S/MIME Active X Control plug-in and restarting your browser; however, Reading Pane functionality for encrypted messages cannot be enabled in Conversations view. Known issue; see Microsoft's Reading encrypted and digitally signed messages September 11, 2015
Some mail-enabled groups cannot be managed from OWA. Managers may find some older mail-enabled groups can no longer be edited from Outlook. To resolve this problem, send mail to sct2@iu.edu with the name of the group, and Support Center Tier 2 will update the affected group(s). Known issue August 5, 2015
Manually configured Exchange profiles do not work. They configure without problems, but display an error and refuse to open when you launch Outlook. If you manually configure your profile in Outlook after the migration to Exchange 2013 and then launch Outlook, you will get an error due to the way Exchange now handles server names. In Outlook 2013 the error message is:
"Cannot start Microsoft Outlook. Cannot open the Outlook Window. The set of folders cannot be opened. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost)."

In Outlook 2010 and 2007 the error message is:

"Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your offline folder file."

Exchange 2013 no longer lets a profile use an FQDN as the server name. Instead, a "connection point" is created that consists of your mailbox GUID and email domain. That connection resembles:

a53e98e4-0197-4513-be6d-49836e406aaa@iu.edu

Thus, you can no longer use www.exchange.iu.edu, outlook.exchange.iu.edu, or ads.iu.edu in the configuration wizard. If you do, you will not get any errors during creation of the profile, but you will when you launch Outlook. If you somehow discover what the GUID is for your inbox and enter it, and also configure RPC over HTTP correctly, Outlook will work. But the vast majority of people have no access to the GUID outside of Outlook's Autodiscover process, so should use Autodiscover to fully configure the profiles.

Profiles configured manually before the Exchange 2013 migration are not affected by this.

For more, see Manual Outlook configuration with Exchange 2013.

Expected behavior July 23, 2015
The OWA URL changed to https://mail.iu.edu/. This is a deliberate change to simplify the URL. Expected behavior June 9, 2015
The OWA login page looks very different. The Outlook Web App login page has been redesigned to bring it more in line with standard IU branding. Expected behavior April 28, 2015
For some users after the upgrade is complete, Lync 2013 or Skype for Business 2015 will display an error: "The Exchange server won't let us connect. We're working on fixing the connection. Your history, voice mail and Outlook features might be unavailable or out-of-date until things are fixed."

There is no pattern for whom this affects.

Delete your SIP profile folder in %userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\. The SIP profile folder will be named after your email address with the letters SIP and an underscore in front of it, for example:

sip_dvader@iu.edu

After that, restart Lync/Skype for Business.

Resolved July 22, 2015
Duplicate Contacts and Junk E-Mail folders After migrating to Exchange 2013, a duplicate Contacts folder and an additional folder called Junk E-mail were visible. This has been fixed with a cumulative update issued by Microsoft. Resolved July 7, 2015
