I used to be able to share to Teams from Outlook but I think I reinstalled Office and now it doesn't work. I have a Share to Teams button in the ribbon that is fully colored in. When I use that a browser is opened and then the Share to Teams box opens like it used to. Previously a browser did not open. When I try to actually share to a Team I get an error message that says:
"! We're still setting up this team. Try again later."
When I open an email and hit the three dots I have a Share to Teams button that is just the outline (I believe this is the newer icon). When I use that I get a different error message that says:
"The property does not exist. The field you want to modify is not valid for this type of item."
I have uninstalled and reinstalled Teams. I have rebooted. I have checked for updates to Outlook. I am running Outlook for Microsoft 365.
