C Wealthall,

Are you getting an error with a particular e-mail account? Which type of account? Gmail? Outlook.com? Or something else?

Which version of Outlook do you have?

It’s an outlook account, emails are fine on my phone but not my Mac. I think from investigating I have to do a process of account recovery 🤦‍♀️

Dear John Buchholz,

Warm Greeting from Q&A Forum.

I understand you're experiencing the issue of unable to send/receive emails in Outlook.

There will be many reasons which can lead to this issue. Could you please share us more detail about:

Your email domain: Are you using a Microsoft 365, Exchange, IMAP, or POP account?
Issue error showed: Do you see any error messages when trying to send or receive?
Issue Time Started: Has this issue just started, or has it been ongoing?

Otherwise, we would like to suggest you to a basic step first before we are diving into more difficult issues:

1.Try connection on Web Outlook version:

Sign-in by Web Browser, other device and with a different network connection.
Send a test email to check again to see if the issue still remains.
Check Mail Storage as in New Outlook for Mac, Microsoft has not yet included a built-in feature to view mailbox storage usage directly within the app.

2. Reconfirgure account:

Open Outlook → go to Outlook > Settings > Accounts.
Select your account → click the minus (-) to remove it.
Click the plus (+) → choose account type (e.g., Microsoft 365).
Enter your email and password → follow setup prompts.
Confirm sync by sending/receiving a test email.

Please don’t hesitate to reach out. We're here to help!

Kind Regard,

Jane Nguyen | Microsoft Q&A Specialist,
