Question details

Users are unable to retain table borders when copying data from Microsoft Excel to Outlook on the web.

Product
Microsoft Excel, Microsoft Outlook 365
Device & OS
not provided
Scenario
Copying and pasting a formatted Excel table into an Outlook web email message.
Observed behavior
Table borders and gridlines disappear in the Outlook message, even though text, alignment, and HTML email formats are preserved.
Before you start

Ensure your Outlook email format is set to HTML and not Plain Text, as Plain Text will automatically strip all formatting, including table borders.

Solution 1Recommended

Use Microsoft Word as an Intermediary (Recommended)

Pasting the Excel table into Word first preserves the formatting, which can then be safely copied into Outlook web without losing borders.

Due to how Outlook on the web parses clipboard data directly from Excel, it sometimes fails to read the border styles. Microsoft Word handles HTML clipboard translation differently, making it an excellent bridge to retain your table's appearance.

1
Copy from Excel

Select the formatted table in your Excel spreadsheet and press Ctrl+C to copy it.

2
Paste into Word

Open a blank document in Microsoft Word and press Ctrl+V to paste the table.

3
Copy from Word

Click the crosshair icon at the top-left of the table in Word to select the entire table, then press Ctrl+C again.

4
Paste into Outlook

Go to your Outlook 365 web email draft and press Ctrl+V to paste the table. The borders should now display correctly.

Use Microsoft Word as an Intermediary (Recommended)
Formatting Retained: This method also helps in preserving complex cell shading and font alignments that might otherwise break in the web version of Outlook.

Frequently Asked Questions

Why do my Excel borders disappear when pasted into an email?

This happens due to inconsistencies in how the email client's HTML editor (like Outlook on the web) reads the clipboard data generated by Excel. The editor sometimes fails to parse the specific CSS or border attributes correctly.

Does changing the Outlook email format to HTML fix this issue?

While setting the email format to HTML is strictly required to display any table borders, a known bug in Outlook 365 web means borders might still be stripped even when HTML format is actively selected. Using a workaround like copying through Word is recommended.

Is this a permanent bug in Outlook on the web?

Microsoft frequently updates Outlook 365. This clipboard parsing issue often appears periodically after backend service updates. Reporting the issue via the Outlook web 'Feedback' tool can help Microsoft prioritize a permanent patch.

Will adding thicker borders in Excel force them to show up in Outlook?

Usually, no. If the Outlook web editor is failing to read the border styles from the Excel clipboard data, changing the border thickness or color in Excel will not bypass the underlying compatibility glitch.
