When I updated to win11, I could not use my old Exchange ActiveSync account in new outlook. How can I use my old Exchange ActiveSync account in win-email(new outlook) ? My old Exchange ActiveSync account not office 365 account.

Hi @ Jie Zheng , Welcome to the Microsoft Q&A platform! Based on your problem description, I would first like to clarify that the new Outlook for Windows 11 does not support Exchange ActiveSync (EAS) accounts. This protocol has been deprecated in favor of other connection methods and is not available in the latest version of Outlook. However, you have several options: 1.Use Windows Mail app: The built-in mail app in Windows 11 supports Exchange ActiveSync. You can add your account there and continue to use it without problems. Please refer to the following steps for details: In the Windows 11 Start menu, search for and open the Mail app. Click the Settings gear icon in the lower left corner and select Manage Accounts. Click the Add Account button. In the pop-up window, select Advanced Settings. In Advanced Settings, select Exchange ActiveSync. Enter your email address, user name, password, server address, and other information. Usually, the server address can be obtained from your email provider. After filling in all the necessary information, click the Sign In or Done button. 2.Upgrade to a supported email service: If possible, consider migrating your email to a service supported by the new Outlook, such as Exchange Online or Office 365.For specific operations, please refer to this document: https://learn.microsoft.com/en-us/exchange/mailbox-migration/migrating-imap-mailboxes/migrate-other-types-of-imap-mailboxes Please feel free to contact me if you have any queries.

Thanks a lot!

For step 1: it only works in old version of Mail APP, but when I re-open the App, it will automatically show the new version, and I can not find the "Advanced Settings" in new version;

For step 2: Due my email belonging our own company, I can't login to office 365 even online.

After my test, in my Windows 11 environment, the method of adding an EAS account in the latest version of Mail APP is shown in the screenshot below.

Hi @Jie Zheng,

Thanks for your quick response.

According to your description, I just found the official document released by Microsoft, which states that Windows Mail, Calendar, and People are being replaced by the new Outlook for Windows. If you want to return to Windows Mail and Calendar, you can do so by selecting the toggle switch in the new Outlook for Windows as you said.

If you are not interested in trying the new Outlook for Windows, you can stop using Windows Mail and Calendar and instead manage your email and calendar through the service's web mail application or other email clients. Support for Windows Mail, Calendar, and People will end in 2024, so if you don't want to use the new Outlook for Windows after the trial, you will need to migrate to other applications before the end of 2024. Details on specific end-of-support dates will be provided in accordance with the modern policy of the product lifecycle.

Please feel free to contact me if you have any queries.

Best,
