Answer 1

Hi Kathy Dzugan

From your description, I understand that Classic Outlook on your Windows PC is stuck in Offline mode, so you can’t send or receive emails, while it still works normally on your phone.

To avoid repeating the Q&A Assist reply, could you confirm have you tried those steps? If yes, what happened when you tried?

In addition, please try the following steps:

1, Fully close Outlook

• Close Outlook completely
• Press Ctrl + Shift + Esc to open Task Manager, find "Outlook" in the list, right-click it, and select End Task to ensure no background processes are still running. Or restart Windows first, then open Outlook.

2, Start Outlook in safe mode

• Close Outlook completely
• Press Windows + R > type: outlook.exe /safe > press Enter
• If it's stable in Safe Mode, an add-in is the likely trigger. In that case, disable add-ins in normal mode and re-enable them one by one:
  • Go to File > Options > Add‑ins > Manage: COM Add‑ins > Go…
  • Uncheck all unnecessary add‑ins, restart Outlook and re-enable one by one to find the culprit.

3, Disable VPN/ firewall temporarily

If you use a VPN or third‑party firewall, disconnect it briefly and reopen Outlook. These can block Outlook’s connection while other apps still work.

4, Repair Office for Windows

Try a quick repair first, and if that doesn't work, try the online repair. Please refer to: Repair an Office application - Microsoft Support

5, Test on Outlook on the web

• Please sign in at Outlook on the web and try testing there.
• If it fails on the web, this points to an account-level restriction.
• If it works on the web but not in the app, the issue is local to the app/device.

Please feel free to let me know how it goes after trying these steps. I truly appreciate your time and understanding.

Answer 2

Use these steps in classic Outlook on Windows to get out of Offline mode and restore send/receive:

1. Check Outlook’s status bar
   • Look at the bottom of the Outlook window.
   • If it shows Working Offline, Disconnected, or Trying to connect…, Outlook is not connected to the mail server and cannot send/receive.
2. Turn off Work Offline
   • Go to the Send/Receive tab on the ribbon.
   • In the Preferences group, select Work Offline once to toggle it.
   • If the Work Offline button background was shaded, it should become clear when you are back online.
   • After toggling, click Send/Receive or open the stuck message in Outbox and send it again.
3. Confirm internet connectivity
   • Open a browser (for example, Microsoft Edge or Google Chrome).
   • Browse to a site such as http://www.microsoft.com or http://www.bing.com.
   • If those do not open, fix the network connection in Windows first; Outlook cannot connect while offline.
4. If Outlook still shows Working Offline in older versions (2007/2010)
   • In Outlook 2010: click Send/Receive, then click Work Offline so it no longer appears in the lower-right corner.
   • In Outlook 2007: click the Offline indicator in the lower-right corner, then click Work Offline to clear it.

Once the status bar no longer shows Working Offline or Disconnected, Outlook should send and receive mail again, just as on the phone.
