New Outlook is unsatisfactory on so many levels. Deficiencies include:

No unified displays - that is, for those of use with many accounts, there is no way to search for a consolidated inbox, consolidated sent items, etc.

Does not accept *@domain.com email addresses, such as used for catch-all accounts on Ionos and other hosting companies..

Ability to "send from other email address" is clunky compared to Outlook Classic

No calendar conditional formatting

Does not support CalDAV or CardDAV for those of us who wish to host our own calendar and contacts on non-Exchange accounts.

No VBA code, required for much functionality, special filtering, etc.

I will NEVER use New Outlook. eM Client is not as good as Outlook Classic, but is far better than New Outlook.

Hi @Barry A Sorkin,

Good day to you! Welcome to Microsoft Q&A.

Thank you for your great question. For your information, classic Outlook for Windows will officially begin its opt-out phase in April 2026, meaning it will no longer be the default experience for most users. At that point, Microsoft will start transitioning users to the new Outlook, which offers a modern interface and improved integration across Microsoft 365 services.

However, it's important to note that support for classic Outlook will continue until at least 2029 for users who installed it via perpetual licensing (such as Office LTSC) or Microsoft 365 subscription plans that include desktop apps. This extended support ensures that organizations relying on classic Outlook for business-critical workflows can continue using it safely and securely for several more years.

Microsoft has outlined a three-stage migration process:

Opt-in phase – currently active, allowing users to try the new Outlook while retaining access to classic Outlook.
Opt-out phase – starting April 2026, the new Outlook becomes the default, but users can still revert to classic Outlook if needed.
Cutover phase – at a future date (not yet announced), classic Outlook will be fully retired for most users, and new installations will only include the new Outlook.

If you're using Outlook through a Microsoft 365 subscription or have a perpetual license like Office LTSC 2021 or 2024, you’ll continue to receive updates and support for classic Outlook beyond 2026. This includes security patches and compatibility maintenance.

I hope this information is helpful. If you have any questions, please feel free to reach out.

I'm looking forward for your reply.

I received an email from [Moderator note: personal information removed] about switching to new version of email. Failure to switch will result in immediate termination of my email account. Is this a legit request? Or spam?

AOL did make some changes to their plans November 2025. But not to AOL email.

https://help.aol.com/articles/changes-to-netscape-isp

Rest assured, your Netscape/AOL email account will remain active and accessible at mail.aol.com at no cost after November 30, 2025. No action is required on your part to keep your email service.

Is that you question?

Anything else, concerning Classic Outlook or your outlook.com email account, is Spam.

The new outlook is terrible, why can users not continue to use the classic version? If I wanted my outlook to look like online, I would use the online version. What are you going to offer to make the experience more user friendly? I do NOT find the new outlook user friendly, everything from the color scheme being hard on my eyes (even messing the settings does not fix this), finding it difficult to see categories, and even my to do list is now a giant window instead of a small bar on the right of my app. Microsoft is purposefully slowing down my experience to get me to switch and it is horrible.

If classic outlook is discontinued that very well may force me to migrate off of O365. The new outlook is not even close yet in functionality

I need the VB for Apps support as I have custom code I run for backing up my email. Further I need pst and auto archive support.

Along with the above, the new version is just plain clunky and hard to use. It is like switching from Excel to Microsoft Works.

I feel MSFT had a good strategy going over all but is now losing it. Getting rid of the password vault support on authenticator was a big mistake and just forced me to migrate that use case to iCloud. MS Access seems to have been left to die and what has gone down with Win11 and the rumors of what will happen in Win12 are discouraging.

Note that Thunderbird, while a great program, does NOT have native support for Exchange accounts.

eM Client is a pretty good substitute for the functionality we will loose when Outlook Classic is gone.
