Replicating is easy. Just put new account Outlook.com to your em Client. Switch on airsync. Syncronize contacts, calendar and task. Wait 1 day and you will get error and no sync anymore
As @Olivia_Rust advised in the “Announcement link” via @Gary post further up in this thread, if you can replicate the AirSync Synchronisation error, then if you are happy to do some troubleshooting you can email the below address to then help find the problem and get it resolved.
Quote extract from Olivia’s post.
“where this issue can be replicated that you’d be willing to provide temporarily for testing, please send the details to [email protected].
It would greatly help us in troubleshooting and finding the workaround to this issue”.
