Avoid Calendar Errors Affecting iOS Devices

The University of Miami IT team has identified an ongoing Microsoft-related issue that may impact iOS devices (iPhone and iPad) accessing University email through Apple’s built-in Mail and Calendar apps—specifically those with Microsoft email accounts.

This issue may result in:

  • Old calendar invites being re-sent unexpectedly.
  • Meetings being unintentionally canceled, sometimes by the person who created the meeting or by someone invited.

If you're using Apple’s Mail and Calendar apps, and something isn’t working as expected, we recommend removing your University email account and setting it up again. This refreshes the connection and can help resolve calendar-related problems.

4. Set a Fixed End Date for Recurring Events

Recurring calendar items without a fixed end date or defined number of recurrences are more likely to trigger this issue.

Before creating or updating recurring meetings, make sure they have a set end date or a limited number of occurrences.
