Using Classic Outlook on Windows for personal email, calendar, and contact management
Test the Hotmail account in Outlook.com first; if typing works there, troubleshoot the Classic Outlook desktop application rather than the mailbox.
1. Isolate the problem
- Close Classic Outlook.
- Sign in to Outlook.com with the same Hotmail address—Hotmail is now Outlook.com.^1^
- Select New mail and try typing a short message.
- Typing works in Outlook.com: Continue with the Classic Outlook steps below. You can use Outlook.com temporarily to write and send email.
- Typing also fails in Outlook.com: Check Microsoft’s current Outlook.com issues page and service status.^2^ If no outage is listed, select Help on the Outlook.com menu bar, enter the problem, and then select Still need help? → Yes if self-help does not resolve it.^3^
2. Test Classic Outlook without add-ins
- Close Outlook.
- Press Windows key + R.
- Enter:
outlook.exe /safe
- Select OK, accept the default profile, and open New Email.
- Try typing in the message body.
If typing works in safe mode, an add-in is likely interfering:
- In Outlook, select File → Options → Add-ins.
- At the bottom, select COM Add-ins → Go.
- Record or screenshot the enabled add-ins.
- Clear every checkbox and select OK. Disable the add-ins; do not select Remove.
- Restart Outlook normally.
- Re-enable add-ins one at a time, restarting Outlook after each, until the typing problem returns. Leave the responsible add-in disabled.^4^
3. If safe mode does not fix it
Run Microsoft’s Classic Outlook troubleshooters first.^5^
If the problem remains, proceed in this order:
- Create a new Outlook profile. After creating it, hold Shift while starting Outlook, select the new profile, and test composing a message.
- Repair Office: try Quick Repair first, followed by Online Repair only if Quick Repair fails.
- If Outlook freezes or shows Processing, close it, launch it once in safe mode, close it again, and reopen it normally.^6^
