Microsoft Outlook Mac Insider Fast 16.11

  • Skip to main content.
  • If you're an Office Insider, see Release notes for Insider Fast builds. Starting with the 16.17 release in September 2018, these release notes also apply to Office 2019 for Mac, which is a version of Office for Mac that’s available as a one-time purchase from a retail store or through a volume licensing agreement.

Office Insider builds for are updated on a regular basis to provide new or improved features, security updates and bug fixes. The newly released version is 16.11 which brings Outlook improvements and fixes. Check out the full changelog below.

Outlook for Mac is adding several highly requested features for Office 365 customers, including the ability to send an email at the time of your choice and request delivery notifications and read receipts. These additions deliver on four of our top 10 requested features, and are designed to help you get more done quickly and stay in control of the day ahead.

A big part of our prioritization of new features and enhancements comes from the votes and feedback we receive from you at our Outlook UserVoice site, and the input we get from our Office Insiders. We thank you all for your feedback and are excited to hear what you think of our new additions!

Here’s a look at what’s new.

Send your emails when you want

The best time to write an email and the best time to send an email may not always align. With our new Send Later feature, you can write an email now and schedule it to be sent automatically at the perfect time. Once you are done drafting your email, click the drop-down next to Send and then select Send Later. Choose the date and time to send the email and the message is saved to your Drafts folder. When the scheduled time comes, the email is automatically sent—you don’t even need to have Outlook or your computer open!

This feature is available to Office Insider Fast users today and coming to Office 365 subscribers in July. For more details, see Can I delay or schedule the delivery of email messages in Outlook 2016 for Mac?

Use read and delivery receipts to track your emails

Sometimes you need to be notified that an important email has been delivered to and read by your recipient. Outlook for Mac now supports both read and delivery receipts. A delivery receipt confirms delivery of your email message to the recipient’s mailbox, but not that the recipient has seen it or read it. A read receipt confirms that your message was opened.

In Outlook for Mac, the message recipient can decline to send read receipts. For more details, see Request a read receipt or delivery notification.

Spend less time writing emails

Sending the same email over and over again? Email templates are great for sending messages that include information that infrequently changes from message to message. Compose and save a message as a template and then reuse it when you want it. New information can be added before the template is sent as an email message. For more details, see Can I create email templates in Outlook 2016 for Mac?

Stay on top of your day by creating calendar events and tasks from emails

Emails contain the important information you need to get things done throughout the day. Often, however, those tasks need to be scheduled as part of your day to get completed on time. You can now drag and drop emails directly to your calendar to reserve that time. The subject of the email becomes the calendar subject, and the body of the email goes in the notes field.

For those of you who are task users, you can do the same thing. Drag the email to your task view to create new items.

Improving the account setup experience

We’ve simplified the Add Account experience in Outlook for Mac. Previously, you needed to know details about what type of account you have (e.g., Office 365 or Exchange, IMAP or POP). Now you can simply enter your email address and Outlook detects your account settings and guides you through the process. And if you’ve signed in to other Office apps before launching Outlook for the first time, you will be asked if you want to add that account automatically. For more details, see Set up Outlook on your Mac.

How do I get all these new improvements?

The Send Later feature is available to Office Insider Fast users today on version 15.36 (170606) and will be available to all Office 365 subscribers in July. The Request a Delivery and Read receipts, email templates, and creating calendar events and tasks from emails additions are available today to all Office 365 subscribers on version 15.35 (170610). The improved account setup experience is available to all Outlook Mac users on version 15.34 (170515).
