I’m happy to help. From your description, I understand how frustrating it is when Outlook says you’re connected but you still can’t send/receive.
Just to confirm, are you using a personal Outlook.com/Hotmail account, or another provider (Gmail/ISP/work email)?
Please try the following:
1, Fully close Outlook
- Close Outlook
- Open Task Manager and end Microsoft Outlook, then reopen Outlook
- Re-check the status bar
You can see this guide: Work offline in Outlook - Microsoft Support
2, Start Outlook in safe mode
- Close Classic Outlook app completely
- Press Windows + R, type outlook.exe /safe > press Enter
- Try testing in Safe Mode
- If it's stable in Safe Mode, disable add-ins (Go to File > Options > Add-ins > Manage: COM Add-ins > Go) and re-enable them one by one to find the culprit.
3, 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
4, Test on Outlook on the web
- Please sign in at Outlook on the web and try sending an email 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.
