A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
I am using CTRL+C and CTRL+V.
Outlook Desktop version 2306 (Build 16529.20154), Microsoft 365 for enterprise.
I updated Office/Windows and restarted my computer once the issue started, but it is still happening.
To clarify: copy/paste works fine from Excel Desktop to Outlook/Word Desktop and from Excel Desktop to Outlook/Word Web. The issue seems to be with Excel Web to anything other than the same browser instance of Excel Web.
Below is what it looks like when I copy/paste into Outlook Desktop - embedded in the upper right is what it looked like in Excel Web.
