Sharing your Outlook calendar with other people is the best way to inform them of your schedule. However, there can be restrictions regarding calendar sharing depending on the kind of account you’re using. There are primarily two ways you can share your calendar: via the Outlook desktop app or the web app.
- If you’re using a Microsoft 365 email, you can easily share your calendar within your organization. However, to be able to share it with people outside your company (e.g., clients, suppliers, family), your administrator needs to change your security and privacy settings. You may contact your administrator for help regarding this.
- On the contrary, if you’re using an outlook.com email, you can freely share your calendar with anyone. This includes people using outlook.com accounts, gmail, or even custom accounts.
