Microsoft has released version 16.90 of Office for Mac, improving the Rewrite feature for the Copilot AI assistant so that it supports fonts and lists and preserves the formatting of the original selected text. Outlook receives collapsible event headers, enables you to initiate an IM conversation directly from an email, helps identify potentially suspicious or phishing emails by displaying a warning, resolves an issue where users received a "Can't Create New Message" error when trying to Reply All to an email, and fixes a calendar bug that blocked adding an attendee to a meeting series that used the "This and the following events" option. ($149.99 for a one-time purchase, $99.99/$69.99 annual subscription options, free update through Microsoft AutoUpdate, release notes, macOS 12+)
