In this post I describe what Microsoft Outlook Spaces (Preview) aka Project Moca is and how to enable the preview of it. Recently, Microsoft made Outlook Spaces available as preview.

What are Microsoft Outlook Spaces?
Spaces is a new way and service to manage and organize yourself and others at a central placed and in a more appealing look and feel.
Key capabilities are as follows:
- organize different things in one space in buckets
- take notes, define tasks and track targets
- save and manage files in OneDrive and other 3P storage services
- create links, contacts and mails
- manage and integrate Outlook tasks, Microsoft To Do, Teams and Office documents (Excel, Word, PowerPoint) centrally
- manage calendars/appointments
- add some gimmicks like locations and weather

How to enable Outlook Spaces (Preview)?
To enable Outlook Spaces you can connect to Exchange Online by using PowerShell and enable the feature for the default or better a certain OwaMailboxPolicy.
Please note: In case you want to test this you might want to create a new OwaMailboxPolicy and assign to a test user (group) and enable it than. I recommend to test this in your test environment first.
#https://docs.microsoft.com/powershell/module/exchange/set-owamailboxpolicy
Connect-ExchangeOnline
Get-OwaMailboxPolicy | fl name, *moca*
Set-OwaMailboxPolicy OwaMailboxPolicy-Default -ProjectMocaEnabled $true
#check user OwaMailboxPolicy assignment
Get-CASMailbox erik...@domain.tls | fl *owa*
Disconnect-ExchangeOnline
After enabling the preview it can take some time until you are able to test it. So, if you open Outlook Spaces you might see “Under construction”, which means that you need to be patient and check it again later.

Update 2020-10-26
I re-checked a while after enabling the preview and noticed that Outlook Spaces are showing up in Outlook on the Web as depicted in the screenshot below.

After clicking on “Project Moca” the Outlook Spaces page opens.

You then create Outlook Spaces to test it.


On the last screenshot I was playing around a bit with what you can do to organize mails and its content in buckets. It’s easy to put content via drag and drop from the right pane to the empty canvas and move it in your order as needed. To me it felt like a virtual dashboard where you can pin important content as need to “link” it or get an overview.
