How to change working days and time in the Outlook calendar

Outlook 2016 2013 2010
The standard Outlook work weekdays are Monday-Friday, and work hours are 8:00 AM - 5:00 PM. The Scheduling Assistant uses this information to show your availability when someone wants to schedule a meeting with you. Skype for Business can forward your phone calls to an alternate phone using this information.

To change your working days and working times in Outlook, do the following:

   1.   On the File tab, click the Options button:

Outlook 365 options

   2.   In the Outlook Options dialog box, on the Calendar tab, under Work time:

Calendar options Outlook 365
  • Modify Work hours
  • Select workdays by checking of days
  • Choose the First day of week and, if it needed, the First week of year.

Note: Unfortunately, Outlook does not allow custom shifts:

  • Different times for different days of the week,
  • The transition of working time in a day, when a work shift begins in the evening and ends in the morning. In this case, Outlook displays the message:
Message in Outlook 365

For example:

Calendar options Outlook 365

To verify the new settings, create a meeting request and click the Scheduling Assistant. It will show the updated work hours and display Monday as a non-working day for you. However, only Exchange users get the full benefits of work time settings because it allows other users to check this information in the Scheduling Assistant.
