Outlook 2016 / 2019 / 2021 / 365 Update for January 2023

The January security and rollup update has been made available for all Click-to-Run installations of Outlook 2016, Outlook 2019, Outlook 2021 and Outlook as part of a Microsoft 365 subscription.

It contains 6 security updates for Visio (4) and Office (2).

In addition, it contains 1 new feature and 1 documented non-security fix related to Outlook Monthly Enterprise Version 2211, and 2 fixes for Semi-Annual Preview Version 2208.

  • Version 2211
    • S/MIME as an Outcome for labelling
      Providing S/MIME encryption and signing functionality as an outcome of labelling.
    • We fixed an issue that caused the focus on the message list to be lost when using CTRL+Tab to navigate from a folder in one mailbox to a folder in another mailbox.
  • Version 2208 Preview
    • Previously, when web add-ins registered for an event in an unsupported scenario, we would simply ignore the registration and return a success. We changed that behavior to return a failure, which ended up impacted existing add-ins, so we have reverted to the previous behavior.
    • We fixed an issue that caused Outlook to fail silently when adding a Modern Group as a shared calendar instead of displaying a sensible error message.

Version 2208 has now also been released to the Semi-Annual Enterprise Channel and contains 4 highlighted new features and 45 fixes which have been made available already to the other release channels. The new features are;

  • Use suggested replies in Outlook
    When you receive an email message that can be answered by a short response, Outlook can suggest three responses you can use to reply with just a couple of clicks.
    • Suggested Replies can be turned off via; File-> Options-> Mail-> section: Replies and Forwards-> toggle option: Show suggested replies
  • One-click writing suggestions
    Apply writing suggestions with a single click. Editor corrects spelling and grammar and gives you ideas for refining your writing.
  • Grammar checking’s got your back
    Outlook marks grammar errors as you type, so you can apply suggestions with a single click.
  • Show multiple mini-months in Calendar To-Do Bar
    This feature allows you to show multiple mini-months both horizontally and vertically in the Calendar To-Do bar.
