Blackberry Sync not syncing calendar properly

Blackberry Sync not syncing calendar properly

Hi there

I have set up Zoho sync on my BlackBerry which is working perfectly for my contacts (changes are going both from Zoho and Blackberry and it is all working fine). However, the calendar sync is not working at all. I have followed the instructions, as well as deleting all the previous calendar items from my BlackBerry but it just won't sync properly.

What am I doing wrong please?!

Many thanks,

Michael
