The basics

If you’ve used classic Outlook, most of MailCraft is where you’d expect it.

Search

Type in the search box at the top (Ctrl+E, or ⌘E on a Mac). Search matches the start of words and ignores capitals and accents. Add these to narrow it down:

Type	To find
from:ada	Mail from someone
to:, cc:	Mail to someone
subject:budget, body:invoice	Words in the subject or the text
has:attachment, attachment:report	Mail with attachments, or an attachment’s file name
is:unread, is:read, is:flagged, is:important	Mail by its state
importance:high	high, normal or low
category:red	Mail in a category
after:2026-10-01, before:, on:	Mail by date
"exact phrase"	Words together
-draft	Leave out mail with that word

For example: budget from:ada has:attachment after:2026-10-01 is:unread.

Flags, categories and pins

On the Home tab, under Tags:

• Follow Up flags a message, with a due date if you like.
• Categorize gives a message a colour category. All Categories lets you add, rename and delete them.
• Pin keeps a message at the top of the list.

Rules

Rules sort mail as it arrives. On the Home tab, under Move, choose Create Rule or Manage Rules. A rule can look at who it’s from or to, the subject, the text, attachments and importance, and can move, categorise, flag, mark as read, set importance or delete. To run your rules on mail you already have, choose Folder › Clean Up › Run Rules Now.

The calendar

Switch to the calendar with Ctrl+2. Click or drag over empty time and type to make an appointment. Drag it to move it, drag its edge to change its length, and hold Ctrl while dragging to copy it. Double-click to open it in its own window, with recurrence, reminders and the Scheduling Assistant.

Working hours, the first day of the week, the clock and time zones are in File › Options › Calendar.

Keyboard shortcuts

On a Mac, use ⌘ where it says Ctrl.

Keys	Does
Ctrl+1, 2, 3, 4	Mail, Calendar, People, Tasks
Ctrl+N	New email
Ctrl+R, Ctrl+Shift+R, Ctrl+F	Reply, Reply All, Forward
