Microsoft's revised announcement states that the Mail and Calendar Apps will no longer be supported at the end of 2024 and will become the New Outlook for Windows.

Microsoft Message Center Details In Part
We will replace the Mail and Calendar apps in Windows with the new Outlook for Windows by the end of 2024.
After this change is implemented:
- Users can no longer use or download the Mail and Calendar apps.
- Users with a Microsoft 365 or Office 365 subscription with access to the Microsoft 365 desktop apps can use the new Outlook for Windows.
- Users can use the new Outlook for Windows with any personal email account (Outlook.com, Gmail, etc.), even without a subscription.
- If you would like to prevent users from adding their corporate email accounts to the new Outlook, you can follow the instructions in this document to disable the application for a single user, group of users, or the whole tenant:
- In mid-September 2023, we will begin auto-migrating Mail & Calendar app users to the new Outlook for Windows with an option to go back if they choose. Users can return to the current Mail & Calendar apps by clicking the toggle in the new Outlook for Windows. We also want to reiterate that these changes will not affect your organization’s use of classic Outlook for Windows.
What you need to do to prepare:
There is nothing you do to prepare now, but we recommend you:
- Let your Microsoft Windows users know about the change to the Mail and Calendar apps
- Start trying and testing the new Outlook for Windows

I already use O365 for Outlook. It also appears you have already squashed my calendar on my Insider build.
What I want is my separate calendar back, the one I have shared with family, the one pulling data from multiple places. Not "Outlook for Windows" which I have no reason to use!
I did not use Windows Mail, but I did use the calendar, and in fact depended on it.
All you're doing with this drivel is making me switch to a shared Google calendar instead. Not what I wanted, but at least I can call up just the calendar, which is what I do want.
The more Microsoft pushes me into the Googlesphere, the more I start looking at other Google offerings to completely replace Microsoft. I prefer to use One set of tools, not a hodgepodge mix and match mess.
So, thanks for giving me one more reason to not renew O365 when the time comes, I guess Google Office Suite it is.Several users have reported issues connecting GMail Accounts to New Outlook. Here are some resources that I found to help. I will continue to update this thread as I find new information. Please if you find anything - Share It.
- You may need to allow 24 hours for the Email emails to appear.
If you have multiple accounts, try adding one account at a time to allow synchronization. My speculation is it may be timing out. Again, this is my speculation - it is not confirmed.
- Make sure you have the latest version of Windows 10 and 11.
Go to your computer and check for updates.
- In this article, a user did not have any issues with his Gmail Business Account but with two of his personal accounts. See the resolution from a MS agent.
New Outlook Personal Gmail Accounts Show No Emails - Microsoft Community
- Mac Users: See this MS article: Known issues syncing Google accounts to the Microsoft Cloud - Microsoft Support
- It also made me wonder if some of these issues apply to PCs.
I hope this helps.

#traccreations4eThanks Teresa, I am trying to get work email accounts/profiles to show up, not gmail or external accounts. When I switch over they do appear but when I click on them it says they are duplicates and the account is already created then they disappear. I will have to try to keep the new version running longer than a day when work isn't so busy to see if it syncs them. If I try to add them it says the account already exists. I keep having to switch back to the current version because I need into those inboxes.
- You may need to allow 24 hours for the Email emails to appear.
- My main concern is resource consumption.
At the current version, new Outlook consumes around 500MB of RAM mostly because it has to bootup Microsoft EdgeView2. Whereas old Microsoft Mail uses less than 100MB.
If the user doesn't have any other application that makes use of EdgeView2 then it means that 500MB will go only to managing email in Windows.
Would you consider adding the option to add third-party accounts into outlook.live.com/mail web client and probably add some PWA support to it ?
That would be greatly appreciated as it will allow to bypass EdgeView2 engine requirements and allow users to make use of the service through preferred browser of choice, with mailto: link handler support already being present in most browsers.
This will make a net RAM consumption around 200MB for Outlook web app which is still an improvement over the new Outlook app.Hi Coddy
Thank you for sharing this information. I don't have any control over or a recommendation to RAM Management. My advice is to give that feedback to Microsoft. It is a legitimate concern.

Teresa_Cyrus - I quickly tried out the New Outlook in the desktop and I saw many good things but I was having troubles figuring out how to get different profiles and although it said an account was added I couldn't find it in the left panel. With the profiles in the current Outlook, it asks me what profile I want to log into before the app opens. Where do we find profiles and missing accounts in the new Outlook? I switched back because I need access to the added accounts and the profiles created.
Hi TanyaVG
Sorry you are having problems with your profiles. To manage the profiles or accounts,
View Tab | View Settings | Accounts | Email Accounts.I also please allow enough time for the accounts to sync.
Please report back and let us know the results. Thank you for sharing your experience.

- Can you run the new Oulook for Windows side-by-side with existing Microsoft 365 Subscription that includes Outlook Desktop? - or -- Does the new Outlook for Windows Replace both Windows 10 Mail App and Microsoft 365 Subscription version of Outlook?
Originally, I was unsure if you could run both Mail App & New Outlook for Windows simultaneously. So I tested it. Here are the results.
I was able to open both versions at the same time.
Note: You can only use either Classic Outlook or New Outlook, but not both simultaneously.
I hope this helps.
/Teresa
#traccreations4eI have been able to open both the current version and the new version of Outlook at the same time. When I viewed the new Outlook I saved the link to the task bar. Then I switched back to the original Outlook. With the link for both versions of Outlook on the taskbar I can open both versions at the same time. I did it to see what some of the smaller changes entailed.
- Is there any hope of adding the features of the current Outlook to new Outlook? It would take the rest of the day to list the missing features.
Hi AmyChapman
It took me some time to compile a comprehensive list of missing classic features. I'm constantly updating the list as users share their experiences, so I understand how you feel.
I'm unaware of Microsoft's process of determining which classic features will make the cut and which won't. Follow my channel to stay updated - as Microsoft rolls out new features, I will publish a video about them.
It's important to continue giving Microsoft feedback about the missing features. The more people share their experiences, the more likely the feature may be considered. When providing feedback, be sure to include details about how you use the feature and how helpful it is, rather than just asking for it to be kept.

- Well, let's start with the ability to add SharePoint "calendars" (i.e. a special sort of list), because that came up yesterday.
And the ability to export your entire calendar.
- Is this downgrade going to be forced on Office 2021 users as well next year, or only those with 365 subscriptions?
Hi phen314,
Based on my understanding of Office 2021. It is a one-time purchase and download. You will not get any new features. These changes should not impact you.
Great question. Thanks for asking. This question will help other Office 2021 users.

- The new app connects fine to my Gmail but does not show any messages. No change after deleting the account & re-connect.
There are also new bugs in the older app (Mail) but no place to report them...Hi Yuval Welis,
Please update your version of the old Mail Application in the Microsoft Store. See the image below of my Mail App version, then try to connect to Gmail again. Also, you should have the Help | Support.
Let me know if this works for you.
- Hi
Just got updated on one of my PCs. But no joy - still no visible messages on the Gmal account in the app,
Teresa_Cyrus It appears that with the removal of com applications, multiple third party apps are going to break sadly. Personally we are noticing Boldon James classifier and Proofpoint's phish reporting application break.
Are there plans to eventually integrate add-ins back to the ribbon?
Thank you for sharing your experience. Just remember, I am an independent advisor, so here are my comments.
You're the first to mention issues with add-ins not functioning properly. I'll need to investigate further to determine the cause.
My initial thoughts are that third-party apps must be compatible due to Microsoft's shift from classic to modern Outlook. It may also be helpful to reach out to the makers of the third-party apps to inquire about their plans. In some cases, these makers may release an application without providing updates for future development.
Also, please give MS the feedback by hitting the Help button and selecting Feedback.
If you find this information helpful, please mark it as the best response or like it which will help others.

- thanks, i have reached out to the third parties involved, one has documentation around how to move forward (proofpoint), while the other i dont hold out much hope for (boldon james classifier) as it looks like they need to update their architecture to support web calls.
pantherfan69 I assume that you are a user of the desktop Outlook application? While the new Outlook can be accessed from the desktop Outlook application, I believe that it is a substitute for the Windows Mail application, and hopefully it will not be a replacement for the desktop application for at the moment, at least, it does not support any automation.
- Correct, the "new outlook" experience is also coming to office 365 users, so it impacts that as well. The issue that i was referring to seems to be related to the switch from com add-ins to web based add ins (as the new outlook is really an updated OWA imho).
I get why they are trying to slowly move everything to the OWA route, i predicted it 10 years ago lol, but sadly third party developers are far behind on the new add-in models, as in some cases like boldon james classifier it requires a new model for their backend architecture to support it.
For your automation issue, i expect the push will be to move that stuff to power platform, which has a lot of stuff already pre-configured for stuff like moving attachments to onedrive, etc.
I've checked out the new Outlook. I'm not liking the calendar changes at all. I work in an office where I have multiple staff calendars open. They no longer auto adjust to view all on one screen and no overlay feature (which I didn't like anyway). I see you can scroll back and forth, but that is more bothersome in a busy office. I also see the Card option for viewing contacts is no longer in the program. I know there's still over a year before it comes out so hopefully they'll put these features back in.
Thank you.
Thank you for sharing your experience. I will add these features to my watch list.
I encourage you to give MS feedback.
Stay connected.

- What about tasks? that's literally the whole best thing about Outlook and we're scrapping it? I really wouldn't know what to do with that feature.
