In addition to the challenge with calendar synchronisation (https://community.mailcow.email/d/2701-calendar-not-syncing-on-mobile-device), I noticed other problems today that seem to affect Active Sync in general.
I am using iOS 16.6 and the latest versions of Outlook and Spark. In the Outlook app, not all emails are displayed. The last 5 emails that were migrated to the mailbox are missing. However, new messages are displayed without any problems. Calendar synchronisation does not work at all. The calendar is simply missing from the overview.
In Spark I see the missing emails, which I don’t see in Outlook. However, the calendar is also missing here. Because I have different results in two different apps, something seems to be fundamentally wrong here.
I have other mail apps like Newton and Canary Mail etc… all of them cannot even be set up. Error message attached:
I don’t know what to do and would appreciate a bit of your support 😉
