@techs: Bug [maybe]. Suddenly was getting a record writing error with the API queries. Turns out the multiboot machine on August 10 somehow acquired a sizeable set of FAHV under Linux and then booted into W10 to not return to Linux ever since. Now I'm getting a record writing error because the ReceivedTime field on those expired No Reply are sent with a null value [nothing] where it is expecting something numerical. Could this be changed?

Alternate, with the open sortkey request on ModTime, could a filter be added for ReceivedTime to only sent <> null or > 0?

For reference, this is an analysis app-tool [compileable for Office32/64] I'm developing and have not come this particular exception in the past 110 12 hour cycles.

Thanks.

P.S. Just powered up to force a device connection to get rid of these and the null error. Sure enough no more error as the RT field is now time populated.
