Iphone => Appointments disappears

[owc]

Hi,

I got a problem for Iphone users.
When a user accept an appointment on zimbra webmail, he receives a notification on his iphone.
When he clicks on "ok" on the iphone => the appointment is moved to the current time.
Ex: I receive an appointment for June 25th. I accept on the webmail.
Then I receive notification on my iphone => appointment move to June 15th.

It seems the bug is present on EAS 14.1 and seems not to be present on EAS 16.
I upgraded max EAS version to 16 on zimbra admin, but some iphones stay at version 14.1.
Is it normal?

I also got lines like this in mailbox.log:
calendar - Encountered time zone with no definition: TZID=GMT+01.00/+02.00

Thank you for your help.
Robin

Hi,

Can you share your ZCS & Zextras version ?

You have to reconfigure account from the device, otherwise you have to wait some iphone do self upgrade to 16.1

Hi,
ZCS version:
Release 8.8.15.GA.3869.UBUNTU16.64 UBUNTU16_64 FOSS edition, Patch 8.8.15_P9.
Zextras version: 3.0.9

All iphones have updated their EAS version. Issue seems to be resolved upgrading EAS 16.1.

Thank you,
