Exchange 2019, 2016, 2013 and 2010 Security Updates for July 2019

News

Security updates have been released for Exchange 2010, Exchange 2013, Exchange 2016 and Exchange 2019.

  • CVE-2019-1084: Microsoft Exchange Information Disclosure Vulnerability (All)
    An information disclosure vulnerability exists when Exchange allows creation of entities with Display Names having non-printable characters. An authenticated attacker could exploit this vulnerability by creating entities with invalid display names, which, when added to conversations, remain invisible. This security update addresses the issue by validating display names upon creation in Microsoft Exchange, and by rendering invalid display names correctly in Microsoft Outlook clients.
  • CVE-2019-1136: Microsoft Exchange Server Elevation of Privilege Vulnerability (Exchange 2010/2013/2016)
    An elevation of privilege vulnerability exists in Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could gain the same rights as any other user of the Exchange server. This could allow the attacker to perform activities such as accessing the mailboxes of other users. Exploitation of this vulnerability requires Exchange Web Services (EWS) to be enabled and in use in an affected environment. To exploit the vulnerability, an attacker would need to execute a man-in-the-middle attack to forward an authentication request to a Microsoft Exchange Server, thereby allowing impersonation of another Exchange user. To address this vulnerability, Microsoft has changed the way EWS handles NTLM tokens.
  • CVE-2019-1137: Microsoft Exchange Server Spoofing Vulnerability (Exchange 2013/2016/2019)
    A cross-site-scripting (XSS) vulnerability exists when Microsoft Exchange Server does not properly sanitize a specially crafted web request to an affected Exchange server. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected server. The attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run script in the security context of the current user. The attacks could allow the attacker to read content that the attacker is not authorized to read, use the victim’s identity to take actions on the Exchange server on behalf of the user, such as change permissions and delete content, and inject malicious content in the browser of the user. The security update addresses the vulnerability by helping to ensure that Exchange Server properly sanitizes web requests.

First look at the new Outlook for Windows interface with a simplified Ribbon

News

Microsoft has released a blog post and a video in which it explains and shows off the design changes that will be coming to Office.com and Office 365.

One of the major visible changes is the new simplified Ribbon. Instead of having a large button or up to 3 smaller buttons on top of each other, the updated Ribbon contains only 1 line of command icons on each of the Ribbon tabs.

Preview of the new single line command bar in Outlook.
Preview of the new single line command bar in Outlook. (captured from the video linked below)

This redesign allows for a cleaner interface with the commands which matter the most and with more vertical screen space left for the actual content that you are working on.

There will also be an option to expand the Ribbon to return the “classic” three-line layout in case you don’t like the change, want to decide for yourself when you are ready to change or when you simply want to dedicate more screen space to the available commands.

Microsoft will start rolling out this new experience in Outlook for Desktop to a select amount of Insiders in July.

Color Code your Emails, Calendar, Contacts or Tasks automatically with Conditional Formatting

Conditional Formatting buttonThe Conditional Formatting feature in Outlook allows you to get organized by automatically color coding your Emails, Calendar items, Contacts and Tasks without the need to apply a Color Category to it or move them to different folders.

The color coding isn’t just intended to emphasize certain emails but it can also be used to deemphasize certain emails such as newsletters or emails you are only a CC or BCC recipient of.

You may actually already know Conditional Formatting without realizing it as it is for instance also being used to:

  • Show unread emails in a blue and bold font.
  • Show expired emails and completed tasks in a grey and strikethrough font.
  • Show overdue emails and tasks in a red font.

The “Conditional Formatting” feature may look complex at first but creating color coding rules is actually fairly easy and quite powerful when used the right way.

This guide will help you on your way to get yourself familiar with the Conditional Formatting options with 8 color coding examples which might be useful to you as well.

Imported IMAP folders are not visible or don’t show any content

IMAP Folders buttonWhen you’ve exported your IMAP mailbox or specific folders to a pst-file which you then later open in Outlook or import into an Exchange or Outlook.com mailbox, you may be shocked to see that these folders don’t contain anything.

Additionally, when you configure this mailbox on a smartphone or tablet as an Exchange ActiveSync account, these folders may not show at all.

Luckily, this can be fixed without any data loss but the process to do so via MFCMAPI is not for the faint of heart or when you have many folder to fix.

Therefor, this guide also contains a script which you can run to apply the fix for you. You can either fix a single folder, a folder and its subfolders or your entire mailbox at once.

Downloading Outlook 2013 from Office 365 after March 1, 2017

Download Office buttonSupport for the Office 2013 versions of Office 365 has ended and are no longer being offered for download in the download sections of Office 365 Home and Office 365 for Business.

If you still have it installed, you will receive Security Updates until April 10, 2023.

Upgrading to Office 2016 is highly recommended and also already part of your Office 365 subscription. However, common reasons why you might still need Office/Outlook 2013 are;

When you still need to (re-)install Office 2013 as part of Office 365 for whatever reason, you can still download it by using a direct link or by using the Office 2013 Deployment Tool.

Autodiscover: Some quick methods to get it working

Autodiscover.xml buttonThe Autodiscover service is a required service for Outlook-Exchange connectivity since Outlook 2007 and Exchange 2007 but for whatever reason, in some Exchange environments this still hasn’t been implemented correctly.

In some part, this was due to the fact that you could still get basic Outlook-Exchange connectivity by using some legacy Exchange 2003 RPC over HTTP dialog in Outlook. This (unsupported) method now no longer works in Outlook 2016 due to the removal of this legacy dialog since Outlook doesn’t support Exchange 2003 anymore since Outlook 2013.

Unfortunately, this leaves enthusiastic Outlook 2016 users disconnected when Autodiscover hasn’t been provisioned correctly by your company.

This guide contains some reasonably quick and easy and some less elegant methods for end-users but also for Exchange administrators to get your Outlook connected to Exchange again. All discussed solutions are fully supported configurations by Microsoft and do not require any changes to Exchange or the need for a new SSL Certificate.

New and Changed in Outlook 2016

Outlook 2016 buttonUpgrading to Outlook 2016 from Outlook 2013 is easy and you’d probably need very little time to adjust yourself to it. In fact, if it wasn’t for the new default “colorful” theme, you’d hardly notice the upgrade to Outlook 2016 at first sight.

This is actually part of the Office 365 strategy where major new features are also introduced during the main lifetime of the current version, as we saw with Office 2013. In the old strategy, these features were held back for the new version. Office 2016 will get the same treatment so future updates can introduce new features as well.

Until then, there are still plenty of new features in Outlook 2016 to use and discover.

Windows 10 (May 2019 Update or earlier) and Outlook

Windows 10 buttonThinking about upgrading your computer to Windows 10 or are you using Outlook on a Windows 10 computer already and are being offered a major Windows 10 update?

What should you be aware of when you heavily rely on Outlook?

The upgrade process from Windows 7 and Windows 8 is actually quite streamlined and trouble free for most configurations. Things are even easier when applying a major update to Windows 10. However, for either upgrade, there are still a couple of attention points before you start.

This guide contains not only upgrade preparation and troubleshooting steps but also various tips about the changes that you could encounter involving Outlook after upgrading to Windows 10.

Outlook can’t connect to Gmail: Password incorrect

Gmail buttonWhen configuring your Gmail account in Outlook (or other mail clients such as Thunderbird and Mail apps on (older) smartphones), you might run into continues password prompts or sync errors.

This is because Google has turned off Basic Authentication by default for all new accounts and accounts which haven’t synced within the last 30 days and only lets you authenticate via the OAuth 2.0 standard.

As a result, you’ll get Send/Receive errors (0x800CCC0E) and could get prompted for your Gmail password again in Outlook and the login will fail even when you supply the correct password.

Solution 1: Re-enable Basic Authentication

To solve this, you must re-enable Basic Authentication for Outlook in your Google Account Settings. This can be done via the “Allow less secure apps” page where you set it to “On”.

By default, Basic Authentication has been turned off in Gmail.
By default, Basic Authentication has been turned off in Gmail.

Solution 2: Enable 2-Step Verification (Recommended)

Another way to go would be to enable “2-Step Verification”. This is a bit more work but also quite a bit more secure and highly recommended.

When you use this solution, you can create a special “App Password” which you’ll then use within Outlook to logon to Gmail rather than using your regular password.

For step-by-step instructions to set this up see: Outlook and 2-Step Verification for Gmail accounts.
