Syncing Office 365 calendar with Outlook 2007

Hi there,


We are a small business with three Office 365 users.  We have set up a team calendar on Office 365 and would like to have this calendar showing up on each of our desktop Outlook calendars.  We would like any new appointments made in our Outlook Calendar to appear in our Office 365 calendar, and vice versa.   Ideally we would do the same with our individual calendars as well.  Is it possible to do this?


Thank you

  • Hi Anna,

    I would like to confirm if the team calendar is the Shared Calendar. If so, please refer to the article below to connect the Windows PowerShell to cloud-based service first.

    Then, please use a user account (such as: User1) to set up a Shared Mailbox and give the users FullAccess permission. You can refer to the following article:

    After that, try to use the Shared Calendar in this Shared Mailbox to share calendar with the User1, User2 and User3. In OWA, the three users will separately receive an email with the subject “I'd like to share my calendar with you”. Please click “Add This Calendar”. Thus, they will see the changes in Shared Calendar from their desktop Outlook Calendars.

    To see the changes in desktop Outlook Calendar from the Shared Calendar, in OWA, it will need to send a share calendar to this Shared Calendar from User1, User2 and User3 separately. Log into the Shared Mailbox, you will see 3 emails with the subject “I'd like to share my calendar with you”. Please also click “Add This Calendar”.
