Using Templates and Quick Parts in New Outlook

New Outlook now supports both Templates and Quick Parts. Unlike My Templates, Templates are full email templates, similar to those available in classic Outlook.

After you write an email, you can save the entire message as a template by selecting Home > Mail Template > Save email as template. To save only a reusable text snippet, select the text and choose Insert > Quick Parts > Save selection to Quick Parts. Quick Parts supports formatted text and images.

To use a saved template, select New > Mail from template to open a new message. Templates cannot be inserted into existing emails, so use Quick Parts from the Insert tab when you want to add saved content to a message you are already composing.

If you currently use My Templates, it is a good idea to create new text blocks in Quick Parts and gradually move your existing My Templates content there, since the My Templates add-in will eventually be retired.

Templates and Quick Parts created in new Outlook are not available in classic Outlook. If you need to use a template in classic Outlook, save it as an OFT file. For Quick Parts, copy the text and recreate the entries in classic Outlook.

Outlook.com Update: SMS Sign-In Codes Are Going Away

Microsoft is phasing out SMS codes as a second sign-in factor for consumer accounts, including Outlook.com. In their place, the company is steering users toward passwordless sign-in options that are designed to be both safer and easier to use.
• Microsoft Authenticator
• Passkeys
• A verified backup email address

Microsoft’s message is straightforward: passwordless sign-in is generally more secure and often quicker than relying on passwords plus SMS. Text messages remain a common target for attackers, while passkeys offer stronger protection against phishing. These alternatives can also make account recovery smoother if you change your phone number or lose access to your device.

I’m still warming up to passkeys, but I’ve started enabling them on my iPhone and in Windows because they add another reliable way to get back into an account. On some accounts, I can also sign in using the same PIN I use for Windows, which makes the experience more convenient.

To add or update your security information, go to account.live.com/proofs/manage.
• Set up at least three verification methods.
• If you use multiple mobile devices, install Microsoft Authenticator on each one.

Handy Outlook and Windows Shortcuts

Outlook includes several keyboard shortcuts that make it easier to move between modules. In both the new Outlook and current versions of classic Outlook, you can press Ctrl + number to open the modules on the left rail. The numbers follow the order of the icons. In the default layout the shortcuts start with:
• Ctrl+1: Mail
• Ctrl+2: Calendar
• Ctrl+3: Contacts (People)

In older versions of classic Outlook, the module buttons appear below the folder list, and the shortcut numbers are assigned directly to each module:
• Ctrl+1: Mail
• Ctrl+2: Calendar
• Ctrl+3: Contacts
• Ctrl+4 through Ctrl+9: Tasks, Notes, Folder List, Shortcuts, and Journal

For Quick Access Toolbar commands, press Alt+1 through Alt+9 to run the matching command. Alt+09 through Alt+01 access the next nine buttons in reverse order. If the toolbar has more than 18 commands, additional shortcuts use 0 (zero) followed by a letter, such as Alt+0A.

Windows uses a similar shortcut system on the taskbar, but with the Windows key instead of Ctrl or Alt. To open apps quickly, place your most-used apps closer to the Start button and use Win + number to launch them. Windows assigns shortcuts 1 through 0 to the first 10 taskbar apps. If an app is already open, the shortcut usually switches to that window. In Outlook, however, it may open a new window unless you create a custom shortcut that uses the /recycle switch.
