# Configure Calendar defaults and work hours

> Set busy-block labels, default meeting length, week start and full-day or half-day time ranges for your MSP.

**Audience:** MSP administrators with Calendar settings access and permission to manage Calendar settings. Company users can [read and filter the Calendar](/user-guides/calendar/filter-calendar-events); they do not change these tenant settings.

Open **Settings > Calendar > General Settings**. These defaults apply across your MSP tenant. They are separate from the current viewer's filters and the [Freeze Windows](/user-guides/calendar/manage-freeze-windows) and [Post-Meeting](/user-guides/calendar/configure-post-meeting) tabs.

## Change general defaults

<Steps>
  <Step title="Choose busy-block labels">
    **Show event details** displays an available subject instead of a generic Busy label for calendar busy blocks. Access restrictions and missing subjects can still limit the details shown. This is not a setting for every meeting, file or private note.
  </Step>

  <Step title="Set the default meeting length">
    Choose **Default Meeting Duration**: **15 minutes**, **30 minutes**, **45 minutes**, **1 hour**, **1.5 hours** or **2 hours**. It provides a starting length for new Calendar meeting drafts. Review each draft before saving it.
  </Step>

  <Step title="Choose the start of the week">
    Set **Week Start Day** to **Sunday** or **Monday**. This affects calendar week layout and date ranges. It does not move existing meetings to another date.
  </Step>

  <Step title="Save">
    Select **Save** in the page header and wait for completion. Switching tabs does not save the draft; unsaved changes can remain when you return to General Settings. Reopen the page to verify the saved values.
  </Step>
</Steps>

Changing these defaults does not rewrite existing meeting start/end times, send invitations or change Microsoft/PSA synchronization settings.

## Set Regular Hours and half-day ranges

In **Work Hours**, edit the Start and End clock fields for each range. Check the hour, minutes and any AM/PM segment shown by your browser.

| Range                                     | Used by                                          |
| ----------------------------------------- | ------------------------------------------------ |
| **Regular Hours**                         | The meeting editor's full-day duration shortcut. |
| **Morning** under **Half Day Settings**   | The morning half-day shortcut.                   |
| **Afternoon** under **Half Day Settings** | The afternoon half-day shortcut.                 |

<Frame caption="MSP example: Regular Hours set to 8 AM–5 PM. Your MSP can choose different defaults.">
  <img src="https://mintcdn.com/msportal/CuJu_16D8ZGdquKW/images/product/calendar-regular-hours.png?fit=max&auto=format&n=CuJu_16D8ZGdquKW&q=85&s=8254bdceeee8d6e8fd12e16689bb2c65" alt="Regular Hours showing Start at 8 AM and End at 5 PM" width="772" height="260" data-path="images/product/calendar-regular-hours.png" />
</Frame>

Each range must end later than it starts on the same day. An overnight range such as 10 PM–6 AM is not accepted here. The form disables Save for an invalid range and displays **Enter valid start and end times, with the end after the start.**

These are clock-time defaults, not a time-zone selector or a rule that prevents meetings outside office hours. Check the Calendar time zone and the final meeting dates/times before saving a draft. A full-day or half-day label uses your configured range; do not assume it always means exactly eight or four elapsed hours.

Select the header **Save** after editing the ranges. Reload to discard unsaved changes and return to the saved defaults.

## Troubleshooting

* **Save is disabled:** there may be no changes, a save may be in progress, or a Start/End range may be invalid.
* **Save fails despite opening the page:** viewing settings and managing them are separate permissions. Ask an MSP administrator to check your role.
* **Busy is still shown:** check whether a subject is available, the saved Show event details setting and your access. [Calendar Blocks visibility](/user-guides/calendar/filter-calendar-events) is a separate control.
* **Existing meetings did not change length:** defaults affect new drafts and explicit duration choices, not previously saved meetings.
* **I need calendar synchronization settings:** use the appropriate [integration guide](/user-guides/integrations/index). General Settings does not connect a provider calendar.
