Hi Aaron,
From the description, you mean that the mails and calendar items are not syncing/displaying properly in the Outlook app on the phone, am I correct? Is Outlook desktop client affected by this issue?
Since this forum focuses more on questions related to Microsoft Outlook desktop application, if only Outlook app for iPhone is affected, I'd recommend you post a new question to the following dedicated forum to get further assistance:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.
If I've misunderstood something, please feel free to let me know. Thank you for your understanding.
Regards,
Steve Fan
