Using classic Outlook for Windows in business environments
Dear @Simone Vilbert,
If you can send emails but aren't receiving them on your new Windows laptop, the previous Mac sync is unlikely to block incoming mail entirely. In Microsoft 365 / Outlook, email storage and delivery happen at the server level.
Here are the most common causes and steps to resolve this:
Step 1: Outlook on the Web (OWA) Log in to outlook.office.com via your browser.
- If emails appear on the web version: The issue is isolated to the desktop app synchronization on your Windows laptop.
- If emails do not appear on the web version: The issue is account/server-wide (e.g., inbox rules, forwarding, or account storage capacity).
Step 2: Turn Off POP3 (If Applicable)
If your Mac was configured using the POP3 protocol with the setting "Delete copy from server upon download" enabled, your old Mac will pull incoming messages off the server before your new laptop can see them.
- On your Mac (or in your account settings), verify if the account is set up as Exchange/IMAP rather than POP3.
- If it is POP3, turn off the Mac's mail app or change the account configuration to Exchange or IMAP.
Step 3: Check Focus / Other Tabs & Rules
- In Outlook for Windows, check the Focused and Other tabs.
- Check your Junk Email folder.
- Verify there are no auto-forwarding rules or inbox rules routing incoming messages directly to another folder.
Step 4: Update Sync Settings in Outlook for Windows
- Go to Send / Receive tab in Outlook.
- Click Update Folder or Send/Receive All Folders.
- Outlook is showing "Connected" in the status bar at the bottom right.
Please check Outlook on the web first to narrow down whether this is a local app sync issue or a server configuration issue, and let me know what you find.
