New Outlook Working Offline: Coming in April 2024


***Update 4/4/2024: The date has changed from January to April. 


The "first set" of Working Offline capabilities for the New Outlook for Windows will be available to all users.

This feature will allow you to access your mail, calendar events, and contacts even when you're not connected to the internet since they will be stored on your device. You can also still perform important actions on your mail, such as flagging, moving, deleting, and composing new messages, to ensure your productivity remains uninterrupted even when you're offline while at the airport or home office.

With my New Outlook user hat on :smile:, several questions came to mind about working offline.  

Gio, There is one reference that I need clarification on. What does "first set of capabilities" mean?

I am aware users will have the flexibility to choose the number of days to download messages to mobile devices is coming soon. 


  • My concern is storage space for these files on both mobile and PC. 
  • The syncing process will surely be done when online. However, will that then take the data offline to strictly online or share properties for both offline and online?
  • What's in the pipeline for future releases that you can share?

I really appreciate any help you can provide.

Did it not happen in January? I still don't have offline support of any kind

Hi @Teresa_Cyrus,

I am frequent traveller and would need to get access to my emails offline. When will this be available?

thank you




I checked again this morning, and it is not available for new Outlook or web yet.
Stay tuned. 

@Teresa_Cyrus, I see the offline feature mentioned in New Outlook help, but I don't see the option in settings. Has it rolled out? See screencap below.





A common occurrence. FAQ documentation rolled out ahead of launch.

Confirms the feature is soon to be released.


It has not been rolled out yet. I am waiting patiently for this feature as well.



And here we are a week later - any updates by chance???

@katrielf - the mail>view>general>offline does not feature on my version of 'new' outlook. Is mine old? How do I move my outlook offline?


@Colin1315 @chbreaux  @katrielf 

Microsoft has not started rolling out this Offline Mode feature yet. I have early access to Outlook features and still don't see this feature. 


Remember, depending on your region, some folks may see it before you. 


I will continue to update this post.

The Work Offline function is now no longer working in the old Outlook either! I have it in my toolbar ribbon, and it disappeared (not sure when). I found it today to add back, but when it appears its greyed out and I still can't access it. I assume this has something to do with it being activated in the new Outlook, but hope this doesn't drag on. I use the function to check merged emails from Word before sending, but they've taken away that ability. Wonder if anyone has any updates?


I will investigate it. I will give an update by the end of next week. It is a holiday weekend in the USA. 

Keep your findings up to date in this thread.  Thanks for sharing your experience.



I had no idea that the new Outlook would not work in offline mode.  Had I known, I would have stayed on the old version.  The update says February/March but it's now April.


Microsoft, the silence is deafening!!!!
