Hi, I am having an issue with my diary. I have setup two exchange accounts on my iPhone. They are from different company (called them C1 and C2) and there is no relation between them, i.e. no domain trust or anything C1 users has no access to C2 and visa versa. Email works fine I am getting email from both system. Outgoing email is also OK. A little issue on diary. As I own C1 my default calendar has been set to C1 (exchange). C2 user can input appointment on my Outlook (in C2) and it shows up on my iPhone, no problem with that. However, if I input something on my iPhone diary it will ONLY go to C1 (my default) so nobody in C2 is seeing that appointment. Ends up double booking my slots. So I am after an app that could help me resolving this WITHOUT changing the way myself and C1/C2 users work. I want an app that will automatically update my C2 diary when I put things on my iPhone. Is there such a thing? Many thanks for the help.
