The first thing most people do when their email looks mangled — weird fonts, giant headings, random indents, or that stubborn gray background no one asked for — is hit Ctrl+Space or click Clear Formatting. That’s almost always the wrong move. It strips bold, lists, and links — but leaves behind invisible HTML ghosts that make things worse next time you reply. I watched a finance team at Alibaba Hangzhou spend three hours rebuilding signatures because they kept clearing formatting instead of resetting the underlying message class.
Quick Answer
To fix Outlook email format reliably, skip 'Clear Formatting' entirely. Reset the message font defaults in File > Options > Mail > Compose messages > Stationery and Fonts, then use Ctrl+Shift+F to force plain-text paste when copying from Word or web pages. For persistent formatting glitches (like emails that always render with Times New Roman no matter what), delete the NormalEmail.dotm template file — it’s buried in your AppData folder and corrupts new messages silently.
All the Methods
| Method | Steps | Best For | Limitations |
|---|---|---|---|
| Reset Default Fonts | File > Options > Mail > Compose messages > Stationery and Fonts > Font (for new mail) > Set to Calibri 11pt | All new messages, replies, forwards | Doesn’t fix existing drafts or replies-in-progress |
| Delete NormalEmail.dotm | Close Outlook → Navigate to %appdata%\Microsoft\Templates → rename NormalEmail.dotm → restart Outlook | Persistent font/size/layout corruption across all accounts | Loses custom signature placement, requires reconfiguring stationery |
| Plain-Text Paste | Copy text → In Outlook, press Ctrl+Shift+V (Windows) or Cmd+Shift+V (Mac) → choose 'Unformatted Text' | Pasting from websites, Word, Excel, Slack | No images or tables — only raw text |
| HTML Source Edit (Advanced) | Enable Developer tab → Select message → Design > HTML Source → remove <font>, <span style="..."> blocks | Specific emails where formatting sticks after replies | Only available in Outlook Desktop (not Web or Mac); risky if you mis-edit |
| Outlook Web Reset | Settings (gear icon) > View all Outlook settings > Mail > Compose and reply > Message format → choose 'HTML' or 'Plain Text' | O365 users stuck in plain-text mode or missing bullets | No font control — only format toggle |
Method Details
How to fix outlook email format by resetting default fonts
This solves 70% of ‘why does my email look wrong?’ cases — especially when replies inherit Comic Sans or 24pt headers from someone else’s signature. Go to File > Options > Mail > Compose messages. Click Stationery and Fonts. Under New mail messages, click Font. Set font to Calibri, size 11, color Automatic. Do the same under Replying or forwarding messages. Don’t just click OK — click OK twice. One click saves nothing. Outlook hides the second dialog box behind the main window.
Now test it: open a new message (Ctrl+N). Type a sentence. Hit Enter, type another line. Both should be Calibri 11. If not, your NormalEmail.dotm is overriding this setting — jump to the next method.
How to fix email format in outlook by deleting NormalEmail.dotm
This file lives in %appdata%\Microsoft\Templates\NormalEmail.dotm on Windows. On Mac, it’s in ~/Library/Group Containers/UBF8T346G9.Office/User Content.Templates/NormalEmail.dotm. It’s Outlook’s hidden ‘memory’ for how every new message starts — including broken CSS, embedded fonts, and leftover signature code. When it gets corrupted (and it does — often after an update or sync conflict), every new email inherits its mess.
Here’s the counterintuitive part: renaming it to NormalEmail_old.dotm doesn’t lose your signature. Outlook rebuilds a clean version on launch. Your signatures stay in File > Options > Mail > Create or modify signatures. But — and this matters — any custom ‘stationery’ (borders, backgrounds, headers) will vanish. Most teams don’t use stationery anyway. If yours does, export it first via File > Options > Mail > Stationery and Fonts > Themes > Save As.
After restarting Outlook, test with a new message. Still seeing Times New Roman? You likely have a group policy forcing it — check with IT. But 9 times out of 10, this fixes ‘how do I fix my outlook email format’ for good.
How to fix outlook format when pasting from external sources
Copying from a PDF, Word doc, or internal wiki and pasting into Outlook is the #1 source of invisible formatting bombs. The fix isn’t ‘paste special’ — it’s Ctrl+Shift+V. That opens the Paste Options gallery. Choose the ‘A’ icon (Unformatted Text). Not ‘Keep Text Only’ — that’s different and less reliable in Outlook 365.
If you’re pasting into a reply, Outlook sometimes ignores this. Then try: paste first, select the pasted block, then hit Ctrl+Space — yes, the ‘Clear Formatting’ shortcut — but only *after* the paste. It works there because the formatting hasn’t yet locked in. This is the rare case where Clear Formatting helps.
Keyboard Shortcuts
| Action | Windows Shortcut | Mac Shortcut | Notes |
|---|---|---|---|
| Open Paste Options | Ctrl+Shift+V | Cmd+Shift+V | Works in compose and reply windows |
| Clear Formatting (use sparingly) | Ctrl+Space | Cmd+Space | Only safe *after* pasting — never before |
| Open Font Dialog | Ctrl+D | Cmd+D | Changes current selection only — not defaults |
| Toggle HTML Source (Dev tab required) | Alt+H, then S | Not available on Mac | Only in Outlook Desktop (365/2019/2016) |
Cheat Sheet
| Problem | Fix | Where to Find It | Time Required |
|---|---|---|---|
| New emails default to Times New Roman | Reset default fonts in Stationery and Fonts | File > Options > Mail > Stationery and Fonts | 2 minutes |
| Formatting carries over in every reply | Delete NormalEmail.dotm, restart Outlook | %appdata%\Microsoft\Templates\ | 90 seconds + restart |
| Pasted text brings weird spacing/colors | Use Ctrl+Shift+V → pick 'Unformatted Text' | Paste Options gallery (bottom-right corner) | 3 seconds |
| Signature adds extra line breaks or font changes | Edit signature in plain text mode → avoid rich-text editors | File > Options > Mail > Signatures | 5 minutes |
| Outlook Web shows plain text only | Change Message format to HTML in Settings | Settings (gear) > Mail > Compose and reply | 1 minute |
