Modes "En cache" et "Hors connexion"

[Xhork]

Hello,

My situation is the following :
- I have lots a roming users
- Migration to Windows XP/Office 2K3/Outlook 2K3 is incoming
- Users will use a single MAPI Profile (as it was done before)
- I need to find the most releavant way to configure the MAPI client
- Exchange Server version is 2K3

Do I need to use the offline mode ?
Do I need to use the cahe mode or a combination of both modes ?

More globally, I have never found any article that gave me quite an accurate
comparison between both modes ?

Thanks a lot to anyone could provide me good info or a least just a link
where I could find a releavant article.

Regards,

Xho

With roaming users, you need to use a direct online connection to the Exchange server, not offline folders, not Cached Exchange mode.

Hello Sue,

Thanks for your answer.
So you mean that for :

- Desktop I can/must use the Exchange cache mode
- Laptop I must continue to use offline folders

Am I right ?

Why technically cache mode is unpropre for laptop that may switch between
LAN, offline and RAS connections ? I have the greatest difficulties to find
technincal explainations.

Thanks a lot in advance.

If users are roaming and you have them set up for either Cached Exchange mode or offline folders, then you'll have a lot of network traffic every time the user logs in to copy or update the .ost file.

It sounds like you didn't tell us the whole story. The only factor you asked about was roaming users, which in the Windows+Outlook context means users who do not use the same computer every day. If you have other factors that apply or if you mean something else, then provide details.

Hello Sue,

Here the situation in more accurate details. I confess that I forgot some
details :

- All our users use local profiles (roaming profiles are not in place). Its
a business decision.
- 50% use desktops
- 50% uses laptops (randomely connected to LAN, RAS or disconnected due to
their activity)
- We intend to activate cache mode for desktop users.
- We wonder if it is necessary to activate both cache mode and offline
folders (OST files)

Knowing that I have not sufficient technical skills I am not able to
determine wether we have to activate both modes or just one (but which one ?)
for laptops users.

I only said that I couldn't find any technical article that answer this
question (though I searched in the engine www.google.com/microsoft).

These are my situation and question.

I hope that I made myself clearer

Thansk U.

Cached Exchange mode uses an .ost file to maintain a local cache for the user's mailbox folders and, optionally, Public Folders\Favorites. It's recommended for use in all but roaming user scenarios, as it provides greater reliability and flexibility.

Ok. So to sum up could you tell me if the following scenario for a MAPI
Profile :

- For laptops users
- Server is Exchange 2000 (headers/mails body download priority won't be
manageable)
- Exchange cached mode will be activated
- MAPI Profile will be configured to "Detect connection state automatically"
so that users won't have to choose between Connected/Not connected (sorry for
thet translation). We assume that Outlook will be "smart enough" to know
wether a network connection is up or not (RAS, LAN, not connected).
- The former technology (with the offline file) won't be used anymore.

Sorry to be so insistant
I have spoken with plenty of workmates (current of past) and we all agree to
say that MS never provided any doc to answer this subject in a business
context.

Thanks
