Using New Outlook on Windows for professional communication and productivity
Hello Wiktor Skonieczny,
Thank you for the detailed information you have provided, it is very helpful in understanding the behavior you are experiencing. I also appreciate the effort you’ve taken to clearly outline the scenario and testing across different Outlook clients.
At the moment, I haven’t seen any official communication confirming this as a known issue in New Outlook for Windows. Given that the behavior is reproducible across multiple users in your organization and works correctly in other clients such as Outlook on the web and classic Outlook, this suggests that a more in-depth investigation would be required to fully understand what is happening in your specific environment.
In this case, I would recommend asking your IT Admin to create a support request through the Microsoft 365 Admin Center, so that the support team can take a closer look from the backend.
You can follow the guidance here: Get support - Microsoft 365 admin | Microsoft Learn
By raising a support ticket, an agent will be able to collect detailed logs, analyze the service behavior, and verify whether there are any tenant-specific factors or service-side conditions contributing to this issue.
This type of investigation is especially important in scenarios affecting multiple users, as it helps determine whether the behavior is related to configuration, service interactions within the product team.
I hope this helps point you in the right direction. Please feel free to let me know once you have an update from the support team or if there is anything else I can assist you with.
Warm regards,
