We are experiencing many synchronization problems on ActiveSync accounts with Outlook 2013 and 2016, for instance a user with the same SM account on 3 devices, 2 PC's with Outlook and an iPhone with OS Mail, the iPhone is equal to Webmail on inbox messages and on Unread Items, but the PC's are different from webmail and different from each other, the number of inbox messages is different and the unread itens is different from webmail and from each other, we delete the Outlook profile, and create a new one and after a full synchronization everything is OK, but after some time other differences appear again.
This kind of sintoms is happening with various accounts, even a user account with only one device, PC with Outlook sometimes has differences from Webmail. This only happens with Outlook 2013 and 2016 on Windows, mobile devices are normally correct with webmail.
Does somes has the same issues or is just us ?
I'm getting tired off SmarterMail, since the release of version 16 we are having various problems, our clients are always complaining...
I need a solution. Thanks.
