Leo, what problems are you having specifically?
We have updated to 15.5. Same issue. Today 2 users, one with outlook 2013 and one with Outlook 2016, lost some emails. Logging in to webmail everything is ok. We are getting problems with active sync almost everyday and we are very disappointed because this problem is not new to smartertools but seem that nobody cares about this. The offical answers are also the same: "Update to latest version", or "buy a ticket" or "we don't have any problem in our tests".
We are workarounding the problem using IMAP on pc and using activesync only on mobile phone.
Seems like Urgent patch is in the works, is that right Smarter Tools?

Yeah, Matt commented on an early post, but I'll add this as a reply:
We have opened an incident with Microsoft on an issue where, when using EAS, moving messages from one folder to another, as well as in other cases, the proper commands aren't being issued back to the mail server. We've replicated it with Outlook and connecting to Outlook.com as well as Office 365, so it's not a SmarterMail issue but definitely an Outlook issue when using EAS. Hence the ticket with Microsoft.

Microsoft's proverbial feet must be held to the fire whenever issues such as these occur. The problem is that SmarterTools can be looked at as a "third party provider." IT heads and email admins can take some refuge behind "We're end-to-end Microsoft" when they are using (Exchange or Office 365) + Outlook, but when the mail server is provided by someone else, and Outlook doesn't perform as it should, the blame can come down disproportionately on IT/email management and the third party software provider. It may not be fair, but it is how things work in some environments.
Today other users with same problem. Outlook is resyncing everything. Every day same thing for someone. It's impossible to work this way
