Activesync logging repeated error

Hi all,
 
I don't expect that I'll get much of a response as this seems more like a ticket issue but I'll give it a go here first. In my SM daily activeSync.log I'm seeing this error with a frequency of every two seconds or greater!

I enabled an ActiveSync subscription a few weeks ago but didn't reboot the mail server for any maintenance reasons until last night. After the reboot, I now have a daily 'activesync.log' file in my log folder. This didn't exist prior to the reboot. Anyone have any ideas of what this means or how I troubleshoot? I'm on 14.4.5801.

Hi Matthew.  I believe upgrading will fix this, as this was in the release notes for SmarterMail 14.5.
 
  • Fixed: A scenario in Exchange ActiveSync where a sync key mismatch could cause a null reference exception to occur which prevents a proper response to the client.
