Outlook.com issues affecting email messages, attachments, and features

ISSUE

Customers using cloud services (including Microsoft services such as Outlook.com and OneDrive) are unable to sign-in or sign-out fully when using the Beta release of the Google Chrome browser (build 78 released on 19 September 2019).

This is because the latest version of the browser changes how cookies are handled.

RECOMMENDED ACTION

Customers are advised to avoid using this Beta version of the Chrome browser while accessing Microsoft services until further notice. Microsoft is working to address the situation before these changes are included in the generally available version of Chrome.

For more information read about the Potential disruption to sign-in and sign-out in Microsoft services in Chrome Beta version 78.

Outlook issues after connecting Outlook to Outlook.com

ISSUE

After connecting to Outlook for Windows (Outlook 2016, 2013, 2010 versions) to your Outlook.com email account, your may experience the following:

  • Your email account name shows up as outlook_[long series of letters and numbers]@outlook.com in the Folder Pane and when composing emails using Outlook for Windows.

  • Recipients will also receive the email from the sender with the outlook_[long series of letters and numbers]@outlook.com format.

  • When recipients reply to the email, the email bounces and you may receive the message “Undeliverable message when you send Internet mail in Outlook.”

This issue only impacts customers using Outlook for Windows. Emails sent via Outlook.com on the web works correctly and emails will be sent with the correct email address.

STATUS

The Outlook client does not currently support using a non Microsoft domain primary alias. For the time being to get the account to work in Outlook you need to change the primary alias to a Microsoft domain account, such as @outlook.com or @hotmail.com.. The Outlook Team is doing work that will enable some supported use of aliases in the near future. We will update this topic as soon as the functionality is available.

WORKAROUND

This issue occurs for users with multiple account aliases. We are actively working on a fix. In the meantime, to fix this issue, please do the following:

Note: If you do not have another alias, click the link on the page to create one "Click Add email and a new alias". Then choose the option "Create a new email address and add it as an alias"

  1. Go to https://account.live.com/names/Manage and sign in to your Outlook.com account.

  2. Set your Outlook.com email as the primary alias.

  3. In Outlook for Windows, remove and re-add the account. See the steps in this article: Add your Outlook.com account in Outlook for Windows

ISSUE

If Outlook is connected to a primary Outlook.com account that is also connected to other secondary non-Microsoft accounts (such as Gmail, Yahoo, etc.), when sending an email in Outlook, you are not able to choose the other secondary connected account as the "From" sending account.

If you manually type in the secondary connected account email address in the "From" field, the email is sent as "On behalf of" your primary Outlook.com account.

STATUS: WORKAROUND

Outlook supports sending from a secondary connected account for Microsoft owned domains such as @outlook.com, @live.com, @hotmail.com but has not implemented this functionality for third-party domains.

The Outlook team is listening to your feedback and investigating adding this functionality to future updates. Please vote up the request and add any feedback on UserVoice: Option to make Microsoft Outlook 2016 work with Outlook.com connected. In the meantime, please use the following workaround:

WORKAROUND

You can also add the secondary connected accounts (Gmail, Yahoo, etc.) in Outlook.com as additional accounts in the Outlook profile.

  1. In Outlook, choose the File tab.

  2. Under Account Information, choose Add Account.

    Add Account command in the Backstage view
  3. On the Auto Account Setup page, enter your name, email address, and password, and then choose Next.

    Note: If you receive an error message after choosing Next, double check your email address and password. If both are correct, see the next section.

  4. Choose Finish.

Currently, you can't use Outlook on Windows to edit calendars that are shared with your Outlook.com account, even if you've reconnected your Outlook.com account to Outlook. We're working to make it possible to edit shared calendars in Outlook 2016 for Windows.

To edit a shared calendar, go online to your own Outlook.com calendar, open Calendar for Windows 10, or use a mobile device. Read how to Add your Outlook.com account to another mail app.

ISSUE

When you try to accept a shared Outlook.com calendar using your Office 365 for business account in Outlook 2016, you might receive the "Something went wrong" error or your sign-in might fail.

STATUS: WORKAROUND

To access the calendar shared with your Office 365 for business account, you’ll need to accept the invitation from Outlook on the web, iOS, or Android. If you've already clicked the Accept button in Outlook 2016, you won't be able to re-accept the invitation from another Outlook application. The person who sent you the invitation will need to remove your permissions and then send a new invitation.
