iPhone Calendar not syncing with MS Exchange (Outlook)

Your device may not be connected to the internet.

Connecting to Wi-Fi is the initial step, followed by establishing an internet connection.

However, it's important to note that connecting to Wi-Fi does not automatically guarantee an internet connection. In the event that you are unable to connect to Wi-Fi, the issue may stem from settings on your iPhone or the router/modem.

On the other hand, if you are unable to establish an internet connection despite being connected to Wi-Fi, the problem is likely related to the settings on your router/modem. In such cases, it is advisable to promptly contact your Internet Service Provider (ISP) for assistance.

Check your WiFi Router / Modem for --> Recommended settings for Wi-Fi routers and access points ...

iPhone Calendar? Apple Calendar? There is no such thing.

Please check which is your Default email Account for the Calendar on your device? Settings > Calendar > Default Calendar

All the devices sync with an email client server which hosts your calendar. If you have a Calendar on iCloud that will not sync with Google Calendar. Settings > Calendar > Default Calendar [Choose what you want]. What you add (Event) on iPhone Calendar is synced with default calendar unless you have chosen a specific calendar at the time of event creation.

To which email account are the calendar events synced with your iPhone? This is not clear in your post

I have had this problem since almost a year now. I have spoken with Apple Support on several occasions as well as with my employers IT support. The only real response so faR has been from IT support that states that Apple have issues with this and that it will be solved in the next OS release ... But I am still waiting ...

Anyone solve this? Maybe a real response from Apple instead of the nonsense answer that was posted earlier? Having the same issue on both Mac and iOS. Someone at Apple broke this big time.
