Recently I migrated company's email to Microsoft Office 365. Because I haven't worked before with Office 365 the process wasn't so easy as I expected initially, but after passing all challenges, I got it done. Next challenge was to create a company calendar so every user can use it. There are few posts on the web that teaches you how to accomplish this task, but none of them was complete as I intend this post to be.

Note: You will need a Windows machine... (I know this sucks, but there is nothing you can do about this).

Well, let's get to work.

First thing to do is to download some  packages that we will going to use to get this task done!

1. Connect to Office 365

2. Create a new mailbox called "Organization Calendar" (you can choose whatever name you like, of course):
[codesyntax lang="powershell"]

New-Mailbox -Name "Organization Calendar" -Alias OrganizationCalendar -Shared
Add-MailboxFolderPermission OrganizationCalendar@organization.com:\Calendar -User user@organization.com -AccessRights Author

[/codesyntax]

3. Go to the Calendar view

4. Right click on OTHER CALENDARS and choose open calendar

5. In the From Directory field search for Organization Calendar created above and click Open.

That's it!
