Failure in adding Exchange account to Apple Mail

As your issue description is primarily written in English, I will provide my response in English for your convenience. Please feel free to let me know if you would prefer the information in another language.

Hi,

Thank you for reaching out regarding this issue.

Referring to Microsoft's official documentation and building on the suggestions provided in the AI response, the first recommended step is to re-enter the credentials for your Exchange or Microsoft 365 account. This can help refresh the connection between Apple Mail and the Microsoft 365 service.

Re-enter your account credentials:

Open Apple Mail and, if prompted, select Edit Settings. Then re-enter the email address and password associated with your Exchange or Microsoft 365 account.

If Apple Mail does not display a prompt, please try the following:

• Open Settings.
• Navigate to Apps > Mail > Mail Accounts.
• Select your Exchange account.
• Re-enter your account credentials.

Remove and add the account again:

If re-entering your credentials does not resolve the issue, please to remove the account and adding it back.

On iPhone or iPad:

• Open Settings.
• Go to Apps > Mail > Mail Accounts.
• Select Exchange.
• Tap Delete Account.
• Return to Mail Accounts and select Add Account.
• Choose Microsoft Exchange.
• Enter your email address, select Next, then choose Sign In and complete the authentication process.

On Mac:

• Open Mail.
• Select Mail > Add Account.
• Choose Exchange and select Continue.
• Enter your name, email address, and password, then select Sign In.
• Select the apps you want to sync, such as Mail, Contacts, Calendar, Reminders, and Notes, then select Done.

For detailed guidance, please refer to Microsoft's official article: Reconnecting your Microsoft 365 account to Apple Mail | Microsoft Support

If the problem continues:

If Apple Mail is unable to configure the Exchange account automatically, please wait a while and try again later.

Alternatively, if you only require email access and your organization permits it, you may try adding the account as an Other Mail Account using IMAP/SMTP settings. Microsoft lists the following server settings for Microsoft 365 email accounts:

• Incoming server (IMAP): outlook.office365.com
• Outgoing server (SMTP): smtp.office365.com

For additional information, please see: Set up email in Mac OS X Mail | Microsoft Support

Additionally, if this is a work or school Microsoft 365 account, your organization may have security policies that require device enrollment or mandate the use of the Microsoft Outlook app instead of Apple Mail. In that case,I recommend contacting your IT administrator to review the issue further and determine whether any organization-specific policies or configurations may be contributing to the problem. If additional investigation is required, your IT administrator can open a support ticket with Microsoft so that the appropriate support team can assist with more advanced troubleshooting.

I hope this information helps. If you have any questions or need further clarification, please feel free to reply. I'll be happy to assist you further.

Thank you for your patience and understanding, and I look forward to hearing from you.

Kind regards.
