If you can’t open Meeting Requests on an iPhone, you are not alone. A client had the same issue on an iPhone 6 and needed my help and I was able to fix it by sliding the calendar option to ‘ON’ in their exchange settings. Thankfully, it worked as my last resort would have been to completely remove the account from the iPhone 6 and then add it back.
Sometimes, setting up Microsoft Exchange on an iPhone is easy while other times, you will find yourself pulling out hairs from your head as you forgot your current password or the correct server domain and has to wait to set up until you can locate the information.
