About two weeks ago I started having an issue where ICS files won't open at all in New Outlook. No warnings or error messages. It just does nothing. The workaround is to Open with... Outlook (legacy).
I'm wondering if it could be related to the fix they just applied for a similar issue: https://support.microsoft.com/en-us/office/outlook-prompts-security-notice-opening-ics-files-after-installing-protections-for-microsoft-outlook-information-disclosure-vulnerability-released-dec-12-2023-df8647ef-1828-421b-a266-79120b6190bd
My IT team hasn't been able to figure it out yet.
