Thanks guys for the opinions Let me explain what Im up against I work for a Broadband Company who does not really understand Citrix Server Farm in the Netherlands.......affiliates around Europe So everytime they accuire a company they go and throw out all their hardware and replace it all new, put in exhange server,sms etc I have suggested we keave there local infurstructure intact and give them our services over Citrix. The response was what will users do if they were working on a train using outlook (no internet connection).........how will they syn back to there mailbox (there will be no local Exchange server, only via Citrix which will be based in the Netherlands) (I have a very small group who dont like Citrix, hence the painful questions) I said give the users UMTS PCIMA cards and there is no issue Thanks to your comment I have a few things to check out with the exchange guys Evan Mann <emann@xxxxxxxxxxxxxxxxxxxxx> wrote: I only have a small number of mobile uses on Citrix. Prior to this, they used Outlook 2003 with RPC over HTTP (as I use for every fat client outside my corporate office). RPC over HTTP, when combined with cached mode, is almost as good, if not better at times, then using Citrix (in my opinion). With cached mode, there is no delay in opening e-mails, but without it, there is delay based on bandwith. Cached mode means your e-mail is delayed slightly for incoming/outgoing, but we're talking < 1 minute even in the worst case scenarios from my experience. Now, having said that, I tell my mobile uses that use Citrix to never use their local Outlook. Ok, so there are a few times we tell them they might want to use it, primarily if they are on an airplane, or need to lookup info. This is still an issue, because, if they never open it to let their cache update, the info they may be looking for is not there. In reality, of the few mobile users I have, only 1 or 2 of them would even use their laptop in an offline mode for Outlook. Those 1 or 2 people are smart enough to understand that they need to let their local Outlook update the cache, and if they compose mail in it when offline, they need to let it send that mail when they get a connection again. What's my point? I think you'll find that if you got the straight and narrow out of your mobile users, you'll find 99% of them don't use their e-mail when they don't have an internet connection, thus they don't take advantage of an offline/cached mode in the first place, and it's not an issue. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Russell Robertson Sent: Saturday, October 29, 2005 5:38 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: OST Files Hhhmmm, I've tried a couple of times to answer this question and I'm not sure hat you want to do. If your mobile user is offline, they are offline. If they use Outlook locally it's going to wait till there is a connection. If you are remote and get a connection, local Outlook can only connect via rpc over http or using functionality via MSAM. This will get your local Outlook connected to remote Exchange. But if you get connectivity, performance is always going to be better (IMHO) using Citrix to connect. Do this help/make sense?
