Using Outlook for iOS for personal email and calendar management
Hi Dimitri Unger,
Many thanks for your update and we sincerely apologize for any inconvenience caused to you.
I understand that you are having the same issue when using a personal account and it only happens in the Outlook web app. Based on the research, if your device is enrolled in the Intune policy, it will impact your device instead of a single account. Meanwhile, it is likely your other Office applications are not updated, so they are not impacted. In this scenario, we would suggest you contact your IT admin to check whether the policy is applied and ask to adjust from their end as your account is fully managed by your Org IT admin.
