Exchange 2016 and the iPhone Meeting Request Bug



We're seeing many complaints that Outlook automatically sends meeting updates to the attendees several times a day. When users delete the responses from their inbox it triggers another update to attendees.
It appears to be a problem only for people who sync iPhones with Exchange 2016.

This issue is caused when iPhone users accept / edit or even view meetings on either their iPhones or iPads with the native iOS Exchange Active Sync.

Symptom
Invitees are receiving constant calendar meeting updates for a meeting created by me  even though no changes have been made.

The updates are being sent every 5-10 min

Workaround
Until Microsoft or Apple releases a fix, use this solution:

Delete existing appointments and create a new one. Regard the following steps to avoid the same issue again.

Other workaround which may work: Disable the “Time to Leave” feature via the “Settings > Calendar > Default Alert times”  > Disable Time to Leave (Source: https://blogs.technet.microsoft.com/ericwhitehill/2017/05/10/smart-forward-on-ios-devices-or-why-am-i-seeing-so-many-calendar-invites/ )

General recommendations:

When you receive a meeting invite wait a few minutes before accepting or processing it.  Allow time for all your devices (phone, desktop, home) to get the message synced to them.

Do NOT accept/respond to meeting invites and updates from your mobile phone or device.  Wait until you are at your desktop (Outlook) to respond from there.

For a person doing the scheduling:  do not create meetings on mobile devices (personal appointments are ok just don't invite others). Use a desktop client or web client to schedule meetings. When an occurrence of a recurring meeting needs to be moved or updated, it is best to cancel the occurrence and create a new one time meeting on the correct date. Also, don't schedule recurring meetings for longer than 6 months.  Start a new series instead.
