Description

I have a full set up Mailcow Server with two mails configured: One for me, one for my girl. When my girl creates an appointment (on her iPhone in her calendar - configured using EAS for Mailcow) an invites me to that appointment (so it will also appear in my calendar), the invitation will be send to me multiple times, on and on once every hour. Not depending on wheter I already accepted that invitation or not. That invitation keeps on popping up in my inbox. it is also reproduceable when she sends the invitation to another mailadress (eg. @live.com) or If I send an invitation to her, she receives the invitation multiple times.

I made a few tests and can now confirm, that this behaviour only happens, when the invitation was sent trough an iOS device. What I tested is:

1. Create an appointment in SOGo and send invitation trough SOGo -> OK
2. Create an Appointment in iOS Calendar App and send invitation trough SOGo -> OK
3. Create an appointment on iOS and send invitation trough iOS -> invitation sent multiple times
