Good morning,
Unfortunately the "copy and paste" option for Excel and Google Sheets have stopped working and instead of pasting the Excel/Sheets table, it only pastes the data.
The "paste as is" no longer working and I now need to copy and paste data from Excel/Sheets to my Numbers program on my Mac and then copy and paste it to the email.
What is even more strange is that I can copy a table from Sheets or Excel and paste it to Microsoft Teams or Word without it giving me any issues.
I would have to imagine that there has been an Outlook update with a glitch because I have also tried changing to Microsoft Edge where it continues to give me the same problem.

This is what happens if I copy and paste the same information to a Teams chat with a colleague:

The information is pasted correctly and keeps the table the same as the original copy.
If I want the same result for an email, I have to copy the information first to Numbers:

And then paste it to the email:

I have spoken with the IT Team at my company but there are unable to guess what the problem is and suggested contacting Microsoft directly.
I would say that it has only been this way, maybe for a week or less but it is annoying to have to work this way adds considerable time to what used to be a routine copy and paste procedure. My colleagues have reported having the same problem as well.
I look forward to your feedback on the matter and kind regards.
