Stop Treating Your Inbox Like a To-Do List

You open Outlook. There are 47 emails.

• Three need proper replies.
• One needs a quotation.
• Another means checking something with a supplier.
• Two involve documents you need to review.
• Somebody has asked you to investigate something that will probably take an hour.

So you flag a few messages. Maybe you mark one as unread. Then you carry on.

Tomorrow you still have 47 emails, except now several have little red flags next to them.

A flag does not create any time

This is the problem with using your inbox as a task list. An email can tell you:

In classic desktop Outlook, a useful way to bridge that gap is to turn the message into a calendar appointment. The email stays attached to the appointment, but now you have also reserved time to deal with it.

An email becomes actual work

Imagine somebody emails:

Keep the original email and instructions with the appointment. Now two things have happened: you have not simply remembered the task, and you have decided when you are going to do it.

How to do it in classic Outlook

In classic Microsoft Outlook for Windows, the familiar route is to drag an email onto the Calendar icon. Outlook creates a new appointment containing the email content.

1. 1Give the appointment a meaningful title.
2. 2Choose when you are going to do the work.
3. 3Decide how much time it genuinely needs.
4. 4Save the appointment.

If your organisation uses new Outlook or Outlook on the web, the menus and supported actions may differ. Use the workflow available in your version rather than assuming that a classic Outlook instruction applies everywhere.

Your calendar shows reality

Most people have considerably more work in their inbox than they have time available to complete. Flags hide that problem. Your calendar exposes it.

If you need 30 minutes for one email, 45 minutes for another, an hour to prepare a quotation and two hours to review a document, that is nearly half a working day.

When those tasks only exist as flagged messages, it is easy to pretend you can somehow squeeze them in. Once they are sitting in the calendar, reality becomes visible.

Do not calendar absolutely everything

You do not need a 15-minute appointment called “Reply saying thanks.” If something takes a minute or two, doing it immediately may make more sense.

Calendar blocking becomes useful when the email represents actual work:

• preparing a proposal
• reviewing a contract
• investigating a problem
• analysing figures
• producing a document
• making an important decision
• carrying out research
• completing a technical task

Those jobs need time, not just reminders.

This is really about protecting your attention

Email has a nasty habit of letting everybody else decide what appears in front of you next. Another message arrives, then another, then another.

If you spend your working day reacting to whatever is newest in the inbox, important work can easily get pushed aside.

Putting work into your calendar changes the relationship slightly. You are saying:

The IT Club view

Sometimes a genuinely useful technology tip is considerably less exciting than a new app or AI feature.

Drag an email into your calendar. Reserve the time. Do the work.

Your inbox tells you what people want from you. Your calendar tells you what you have actually decided to spend your time on. Those should not always be the same thing.
