For Outlook on Mac, how to stop signature automatically being added to calendar events

Question

This never used to happen, but recently when I create a new calendar event, or edit an existing event, my email signature is automatically added to the notes of the event.

I go to Signatures to try to adjust but the only options I can choose is New Message or Replies, no options for New Calendar Events. There is no distinction or selection I can choose for New Calendar Events. I can choose no signatures for New Message and that will stop the signatures to my calendar events, but then that also stops my signatures on actual emails, which I do need so that's not a solution. Is there a way to separate the signatures from New Messages vs. New Calendar Events?

This is extremely frustrating and it just started happening about a week or so ago.

Answer 1

You're not alone—many Outlook for Mac users (including myself) have recently reported that their email signature is being automatically inserted into calendar events, and unfortunately, there is currently no built-in setting to disable this behavior independently from email signature settings.

As of July 2025, Microsoft has not yet released a fix or toggle for this behavior in Outlook for Mac

It’s being tracked as a known issue, and users are encouraged to report it to help prioritize a fix.

Answer 2

Same here, very annoying

Answer 3

YES ... totally annoying ... please address

Answer 4

Same problem and this is incredibly frustrating. My signature has my Zoom meeting link in it, so every time I create or even edit a calendar event, Outlook both includes my signature AND labels the event an online meeting.
