This is an odd one. I have the BB 8310 and when I try to sync using DM 4.7 all is fine except for one thing, the calendar refuses to sync. The following error is what I get;
"Access to the current record is denied, Validate your permission to access the record"
When I check the sync log on DM 4.7 it says "internal error #4238"
What I have tried.
1) Totally diff computer with DM 4.7 and it only syncs 27 calendar entries (i have thousands)
2) Different sim card
None of these fixed this. So I think the problem is a setting on the phone.
