Share a specific user's calendar with all employees

Hello, @abderrahmane belabes,

Welcome to the Microsoft Q&A platform!

To share a specific calendar within a mailbox, you need to follow the right steps to ensure that you're sharing the correct sub-calendar rather than the default one.

Here’s a general guide on how to share a specific calendar in Outlook:

1.Open Outlook and go to the Calendar view.

2.In the left pane, under your 'Events' mailbox, find and select the 'Parties' calendar.

3.Right-click on the 'Parties' calendar and select Sharing Permissions.

• In the Sharing and Permissions window, click Add.
• Enter the email addresses of the employees you want to share the calendar with.
• Set the appropriate permissions (e.g., Can view all details).
• Click Apply.

4.Ask one of the employees to check if they can see the 'Parties' calendar in their Outlook. They might need to go to Add Calendar > From Directory and search for the 'Parties' calendar under your 'Events' mailbox.

Moreover, using a shared mailbox can indeed simplify the process of sharing calendars with multiple people. A shared mailbox allows multiple users to access a common mailbox, which often includes shared calendars, emails, and contacts.

If you encounter any issues, you might need to add the employees to the Full Access list in the Exchange Admin Center. At the same time, double-check if there are organizational policies or restrictions regarding calendar sharing, especially if sharing with external contacts.

If you are using the File > Open & Export > Other User's Folder functionality, it only work for default Calendar folder, not any additional ones. To access non-default shared calendar, you need to instead use File > Account settings > double-click the account > More settings > Advanced > Add and enter the name of the mailbox. This method will expose all folders within said mailbox to which the user has been granted access, not just he Calendar.
