Using New Outlook on Windows for personal email, calendar, and contact management
You used to be able to simply click a button to add your signature to a calendar invite. However, in the new updated version, it appears that this function is no longer available. The only workaround currently is to manually copy and paste the signature from another email.
Please consider restoring the 'add signature' function for calendar invites.
Agree. Seems like Microsoft rushed through this upgrade process and skipped over seeking the advice of actual users that would provide honest feedback. Any user of Outlook would have given true feedback about keeping this, along with several other functions that were not carried over to the New Outlook.
