Over the past 5-yrs, organizations have complained about Microsoft Outlook calendaring problems where users describe issues of calendar appointments not showing up, meeting appointments disappearing, calendar delegate issues occurring, just overall 'odd' behavior of calendars. It usually happens in mixed environments where some users are Apple Mac users, and some users (frequently the exec admin / delegate) running Windows, and typically active use of iPhones, iPads, Android, or other mobile devices and tablets. And over the past 5-yrs, I have actively blogged about the problem and the solution to FIX the calendaring inconsistencies. This is a April/2015 update that I'm glad to post as there is FINALLY a great solution to the problem.
More specific to the noticed challenges:. Lost Appointments: Appointments sent to someone, the person accepted the appointment, but now the appointment isn't in their calendar anymore. Duplicate Appointments: Having the same appointment show up multiple times in the calendar. Appointment Corruption: Appointments (typically recurring appointments) that cannot be opened as an error notes 'Cannot read one instance of this recurring appointment. Close any open appointments and try again, or recreate the appointment'. Odd Delegate Issues: Where a Boss/Delegate relationship is challenged by the delegate not getting appointments consistently, or approvals not showing up as approved I originally blogged about the problem and the (then) solution back in 2010.
Here's a link to the original article: Since writing that article back in 2010, I’ve since written several other “how to fixes” to the various problems including as well as What is typically common with disappearing and corrupt appointments that happens between Exec and Exec Admin occurs when an appointment is scheduled on a Windows PC (or Mac), accepted on a Mac (or Windows PC or iPad/Android tablet/device), and then slight modification to the appointment from a different make/model of device occurs. So an Exec using a Mac, with an Exec Admin using a PC will almost certainly corrupt the calendar appointment as they accept, change, modify appointments in the shared delegated calendar. Or an appointment created on a Windows PC, accepted on an iPad, while either the Exec or Exec Admin uses a Mac will also surely corrupt the calendar appointment. The above articles go through the technical details of the issue, that I clearly reference Apple Tech notes and Microsoft Tech notes of the root problems, however the challenges over the past several years is as soon as Apple fixes a bug on their end, Microsoft comes out with a patch or update that injects a new problem, and then Apple comes out with a new version of their email and calendar client (for iPads or Macs) that then causes corruption that Microsoft patches and fixes.
It was an ONGOING back/forth problem that was very difficult to keep on top of. To summarize the technical issues that create the problem, when say for example a calendar appointment is created on a PC, that appointment has a unique message ID that links together the calendar appointment and any recurring instances and attachments to the appointment. However various versions of the free calendar app that come with the iPad, iPhone, even the Calendar app native to Apple Macs (and even Microsoft's own Entourage and Office 2011 for mac) had varying behavior issues that do not always adhere to the associated appointment message identifier that Exchange (and Office 365) uses. So in varying instances when the appointment is accepted and changed on an Apple device, the appointment ID is changed, the attachment is detached from the appointment and given a unique message ID, and recurring appointments are split up and saved as separate individual calendar appointments. Effectively, the calendar appointment on the Mac or iPad is now disassociated with the original Windows-based calendar message ID. When the appointment is changed, updated, modified, different behaviors kick in that delete the appointment on one type of device (but not others), or an appointment deletion on the PC side doesn't delete the new appointment ID that was created on the Mac, etc.

This is the root cause of the problem that I go in to more detail in the other blog posts and briefly summarized here in this update. So how does one SOLVE this calendar corruption problem today??? The solution requires 3 fixes:. an updated and reliable backend environment (ie: the latest Exchange 2013 or Office 365 in the cloud).
use of the latest Microsoft provided client software (ie: Outlook 2013, Outlook for the Mac (2013 or 2016), iPad/iPhone/Android Microsoft provided Outlook client). good user behavior Many orgs have begun migrating off Exchange on-premise to Office 365 in the cloud that has solved a big portion of the problem. With Microsoft's updated backend environment, a third of the problem has been addressed.
But that doesn't solve the entire problem. As noted, organizations need to get to a consistent client software as well. If users continue to use the built-in Apple clients against Office 365, they'll still get quirky issues with delegates because the free Apple clients (for Mac and iOS) have varying quirks to them that Apple fixes, then Microsoft fixes to work around the Apple fix, that Apple then works around to fix the fix that Microsoft injected, etc Here’s the best solution:. Update your client software to use ONLY the latest Microsoft versions of software.
