I am currently using Blackberry 9700. I am facing strange issue and I have decided to discuss with you all. Well I am using BES 4.1.6 Lotus Domino on v18.104.22.1683 (Platform 22.214.171.124). Well in my situation I am having duplicate calendar entry on my phone. I think there is compatibility issue between device and BES. I am not having any idea to work around this particular situation. Any suggestion will be highly appreciated. Thanks a lot in advance.
