ActiveSync randomly stops working Blackberry 10 since 1.8.17 upgrade

[FiZi]

I don't know if this helps at all but I've found someone else with a similar to identical problem using the same OS versions as me but with a different model (Q5 instead of Q10).

They use http://www.zarafa.com/

Update: The same user using the above product reports the exact same syncing bug you fixed/worked around in the custom build. They also would set a sync interval on their phone and all sent items would sync. Doesn't look like the issue is specific to your implementation of ActiveSync and might be a bug in Blackberrys device that doesn't happen on a Microsoft ActiveSync server.

You may be able to work around the issue by setting scheduled sync every 5/15 minutes instead of push.

I've switched to 15 minute syncing instead of Push to see if this eliminates the problem.

After switching to a 15 minute sync the issue re-occurred. It felt like it took longer.

I then changed back to Push. The issue re-occurred.

I am back on a 15 minute sync to see if the issue occurs again.

Confirmed. Even with a 15min sync instead of push this issue occurs.

Hello FiZi!
We received multiple reports about the same issue and we're still investing the possible causes to see if there's a chance to apply a server-side workaround...
Are you running the very latest BBOS version?

Thank you for looking into it.

I was running the latest OS available from my carrier (10.2.1.3247) when I first reported the issue and I am now running a newer, beta version of BBOS and still having the issue.

This might be related. I use a StartSSL Wildcard SSL certificate on my web server.

I haven't tried disabling SSL on my account.... I kinda don't want to either

Fyi I've switched to an iPhone 6 which has obviously solved my problem. I still have my Q10 and am more than happy to continue troubleshooting and testing bug fix releases.
