Hi aLL, I had this issue.
When i Sync my HTC touch with Gmobile i had this Error Message " NullReferenceException"
But if i change it to:
Syn Previous Days 7
Sync Future Days 7
There is no error. BUT the Calendar DID NOT update on both Gmail and HTC.
The error will appear when i set to Sync more than 14 days( Future ).
HTC Touch ( CE OS 5.2.1238 (build 177220.127.116.11 )
Can anyone advice please ......... THANKS !!
