Hi all. Here is my situation. We run IceWarp email server at work. Our company is too cheap to spring for the Microsoft Active Sync plugin for all the email users in the company to use active sync. So, we are using CardDav and CalDav to sync to the email server to get contacts and calendar appointments. We use IMAP to get emails to the phones. It seems to work fluid enough. HOWEVER....Since iOS 7 there seems to be some kind of glitch in iOS in regards to CalDav. It brings in double and triple appointments. Then if you edit the appointment in Outlook (which then syncs back to the email server), it brings in another duplicate entry into the iOS Calendar. I'm fairly certain this is an iOS bug, because the few people at work that use Android and Caldav app do not get double and triplicates in their calendars, only iOS users. And, this didnt happen back on iOS 6. So, my question to all of you is this....is there an alternative Calendar app for iOS that will use CalDav? I've looked at Outlook, but it obviously only syncs with major services like GMAIL, Yahoo, Outlook.com, etc. It wont use IMAP and CalDav. Thanks!
