How to Open Another User's Calendar in Outlook Web Access

Outlook Web Access Web Parts lets you access Outlook Web Access content directly from a URL
To do this, the account you use must be delegated at least reviewer access to the calendar folder of the mailbox.
  1. Enter the following URL:
    https:// Outlook Web Access URL /owa/ SMTP address of the other mailbox /?cmd=contents&module=calendar
    • If you are already logged on to Outlook Web Access by using a user ID that has at least reviewer access, the calendar will open immediately.
    • If you are not already logged on to Outlook Web Access, you will receive a logon prompt. Log on by using a user ID that has at least reviewer access to the calendar.

For eg, if I want to access Sean calendar via webmail, Sean will need to give me reviewer or editor rights to his calendar.
Here is what I'll type to access Sean's Calendar
https://OWAExternalURL/OWA/Sean@domain.com/?cmd=contents&f=calendar&view=weekly

Login with your username and password and the calendar will open immediately in weekly view
