Exchange sync not for business use?

Hello out there clever guys and girls,

I recently got the Samsung Galaxy S. It's a very nice phone, I like it a lot, but:
is it a .... phone for business use       ???

My SGS syncs with the MS-Exchange server of my work (at VU university Amsterdam). I have the following problems with the standard Samsung agenda application and with the standard Samsung e-mail application of the SGS.

Agenda:
-Maximum of data to sync with the MS-Exchange server account is only 1 month (!). This results in the annoying problem that I cannot go any further than 1 month from today in viewing my appointments in the SGS. When I try to go to a date after 1 month from today, the agenda application (proces com.android.calendar) is forced to close down.
For business use this sucks a lot. I realy must be able to sync and adress more agenda data then only data up to 1 month from now.

Am I doing something wrong here? Is there a agenda app for the SGS that allows a better synchronisation for the agenda with the MS-Exchange server?


E-mail:
-The folder structure (main folders, sub-folders, sub-sub-folders) is not synchronized correctly. All the folders are listed at the same level. This results in al list of a couple of hundreds (!) of folders without any hierarchy. This sucks to.
-In the SGS e-mail app I cannot move read e-mail to a folder when I am ready with it. So I cannot archive the mail while I am on the road to a folder (or sub-folder) of my choice.

Again:
 am I doing something wrong here? Is there a e-mail app for the SGS that results in a better synchronisation of e-mail and folderstructure with the MS-Exchange server?

Are these problems solved in android 2.2?

I will be very gratefull for your replies. I am not a bits-and-bytes pilot so I realy need you help here.

Thanks a lot,
Jan-Willem

I will try to find out what version of MS-Exchange we are using. In the meantime my agenda crashed completely and will not start at all anymore. Is there a way to re-install only the agenda? Or do I need to do a factory reset now?

By the way, you recognized my e-mail problems; do you no a better e-mail app?

Cheers,
Jan-Willem

@Jan-Willem:
For email, I have no alternative (because the synch is kinda embedded, don't think a third party can do it better), so I just do simple email on my Android, and the moving and deleting, I just do it on the desktop.
Also, can you check if clearing the Calendar cache helps, since you can't start it at all now ? It's in Settings > Application > Manage Applications (make sure menu key > filter > is set to All) > Click Calenda > Clear data

For both @Jan-Willem (after your Calendar starts working again) and @bionksie, are your Sync contacts and Sync calendar checkboxes checked (green) ? It's on by default, but check again at Settings > Accounts and Sync > Click on the Exchange account in question > Account settings (scroll down a bit)

Good news! First of all, Froyo is out for NL (as I know, I just updated it through KIES). Second of all, default email app now has Move to Folder command. Folders still same level though (Android just doesn't like tree structures I guess, unlike Windows)

Is K9 client an app for android? Can I install it on the SGS?

Cheers,
Jan-Willem
