Signature button missing from Insert ribbon when scheduling a meeting

Question

In the past, when creating a meeting users have have the option to select which signature to use. This has been handy in the event the meeting is not a Teams meeting and they want to change from the Teams information to their standard signature.

Sometime recently however this button has disappeared. When scheduling a meeting and going to the Insert tab the only options are Attach File, Outlook Item, and Business Card. This is happening for every user I've checked on.

• We're using Exchange Online and Outlook 365 (build 2306 and 2307).
• The button shows up when opening Outlook in Safe Mode.
• I've reset the view settings on an affected machine with no change.
• I've reset any ribbon customizations on an affected machine with no change.
• I've disabled all Outlook add-ins on an affected machine with no change.

An interesting thing to note (and why I think it's just a bug) is that if I go to customize the ribbon, it shows the Signature button should already be there.

However as you can see in the screenshot it isn't showing up.

As a temporary workaround we've just created a new group and added the Signature there, which shows up fine.

Is there something else I'm missing? The button is present in other locations (composing a new email, etc) but not on the New Meeting page.

Hi @Joe Grover ,

We're using Exchange Online and Outlook 365 (build 2306 and 2307).

Could you share the detailed build number via File > Office Account > About Outlook?
I checked it in my Outlook 365 Version 2307 (Build 16626.20170) and can still see the Signature button when scheduling a meeting:

Besides, in case it has something to do with the Shared Calendar Improvements feature in Outlook, I suppose you could try it on one of the affected machines by disabling it:

1. In Outlook, select File >Account Settings >Account Settings. Select the affected email account and choose Change.
2. Choose More Settings, followed by the Advanced tab.
3. Clear the checkbox next to: Turn on shared calendar improvements.
   
4. Close and restart Outlook.

Moreover, if the above doesn't work and you still suspect it could be related to any change in recent update, you can consider using either of the methods below on one problematic machine to check the result:

1. Revert to an earlier version of build of the current update channel. Detailed steps, you can refer to: How to revert to an earlier version of Office.
2. Change the update channel to a slower one like SemiAnnual and see it the signature button can appear. For instructions about changing the update channel, you can see How to Change the Update Channels for Microsoft 365 Apps.(Please Note: Since the web site is not hosted by Microsoft, the link may change without notice.
