Thank you for reaching out to Microsoft Q&A Forum. I understand you’d like to speak with Microsoft Support by phone, especially when your email works on the web and phone, but not in Outlook on your Mac.
Could you please confirm is your BT email set up in Outlook for Mac as IMAP or POP (or do you know which)?
Please try these steps before contacting Microsoft Support team:
- Make sure Outlook isn’t set to “Work Offline”
In Outlook for Mac, check the Outlook menu and confirm Work Offline is not selected.
Also confirm your Mac has a stable internet connection (try loading a few websites).
- Re‑enter your password / refresh sign-in
If it works on your phone/web, the Mac app may be holding an outdated sign-in token. Microsoft recommends verifying credentials and account settings in Outlook for Mac.
- Remove the account from Outlook and add it back
- Open Outlook, click Outlook > Settings > Accounts
- Select the affected account
- Click the – (minus) button to remove it
- Close Outlook then reopen Outlook
- Click Add Account
- Sign in and let Outlook fully re‑sync the mailbox
- If you want to reach a support agent
Once you’ve tried the steps above, you can also reach out directly to the Microsoft Support team. For personal account/product It mainly offer live chat and, depending on your subscription/region, an option to request a callback:
- Please go to Contact - Microsoft Support and sign in to your account.
- Type a brief description of your issue in the search box.
- Click "Get Help", then scroll to the bottom and select "Contact Support”.
- Choose the appropriate Products & Services/ Category.
- Look for and select "Chat with a support agent in your web browser" (during business hours) or a similar callback option (if available). Explain your situation clearly.
