I have a client with an iPhone that connects to his exchange account via activesync.
he seems to be getting mails ok, but there is sometimes a huge lag in updating calendar entries and sometimes they need to be removed and readded to make them appear on the iPhone.
Anyone else experienced this problem before? I am not sure how often the iPhone (on UK Vodafone) checks with the server or of it could be a problem with the server (2003/Exch 2007) not pushing the data to the phone.
Any help would be appreciated.
