Hello,
Thank you for posting in Q&A forum.
First of all, we regret for the inconvenience caused to your work. Based on your description, I have a general understanding of your question, please kindly refer to:
On the View tab, select View Settings.
- Select Accounts > Signatures.
- Select New signature, then give it a distinct name.
- In the editing box below the new name, type your signature, then format it with the font, color, and styles to get the appearance you want.
- Select Save when you're done.
- With your new signature selected from the list above the editing box, go to Select default signatures and choose whether to apply the signature to new messages and to replies and forwards.
- Select Save again.
In addition, unluckily the option to add signature to a meeting invite in the new Outlook it doesn't seem feasible at the moment. We understand your feelings, but unfortunately, our forum does not have permission to help you change, because the default feature changes of the product are decided by the development team and the design team of the product. And about your suggestions, I also believe that this is the voice of many users, everyone is anxiously looking forward to early improvement, in order not to waste more time and better help you, I strongly recommend that you submit your valuable suggestions to outlook feedback so that relevant technical developers and designers can see your valuable suggestions. Please believe that the relevant departments of Microsoft will strive to improve themselves after seeing your valuable suggestions, and your valuable opinions will also help more users and make the work more efficient. Thank you in advance for your contribution!
And about how to give feedback to outlook please kindly refer to Contact support and provide feedback in new Outlook for Windows - Microsoft Support
