Currently, start day for the week and the work-week are set based on your language in Settings in Microsoft Teams. The Calendar team has work on the backlog to address the case where users may want a different week/work-week start day than is usual for their language setting.
Until then, the team wanted to share this workaround for setting the work-week start day via OWA, while leaving your language settings as-is.
- Open Outlook Web Access (“OWA”), and go to the Settings panel, as described in this article: https://support.microsoft.com/office/calendar-settings-in-outlook-web-app-84544ef2-d5cf-4696-bcb3-cc87719a3e07.
- In the OWA Settings, click “View all Outlook Settings”
- Use the settings under “Show work week as” to choose your work-week days.
- Click “Save”
- Return to Teams, click on your photo/initials at the top right and choose “Sign Out”
This item remains on the backlog.
