Sending, receiving, and organizing email in Outlook.com
I understand how disruptive this is, especially since copying formatted tables from Google Sheets previously worked correctly.
Please first try Outlook.com in an InPrivate or Incognito window and temporarily disable browser extensions. If the behavior continues in another supported browser, it may indicate a change affecting the Outlook.com compose editor.
As a temporary workaround, use Insert > Table in the message draft, then paste the cell contents into the Outlook table. Outlook.com officially supports creating and editing tables directly within messages. Insert or edit a table in Outlook.com
