Exchange online and Citrix
Exchange online and Citrix
- Hi,
I have a large Citrix enviroment spread across 5 Regional data centers. About 9,500 users in thin client.
Currently we use Lotus notes but are looking at moving to an exchange solution. The IT operations team is not the best so a hosted solution is the prefered option.
I have done some testes with the Microsoft Online solution but have came across the same old issue of cache mode on terminal servers.
Is this looking at being resolved or is there a work around for this.
I would like to move the 13,000 users into the Ms system, but if this cannot be resolved then i am going to have to look else where.
Ideas welcome.
Thanks

What Cache mode problem are you referring to? I am currently running a TS Citrix environment. I only have 5 users on my test server but things seem to be running fine.
- Make sure you have the most recent version of Outlook hotfix and SP. The full version of Outlook running in a thin client environment really defeats the thin client approach. When Outlook does it's sync with the server it is taxing as well as storage on the Citrix server for the ost files. What I have seen a lot of companies doing is only allowing OWA connections which will give you good speed and keep the hardware overhead low.
David Allred - Yes, but that is not really an option for us.
I am not worried about storage or access speed. The SAN and the EMC kit we have can handel it. We are looking at using the MS Online Exchange enviroment, so the cache function is critical.
We are now working with the outlook developers on the issue.
So should be intresting. - With our situation, the Citrix servers are in the Data Center. Link speed to MS is great. What we need is to be able to configure the single sign on not to cache. We have ERP systems that call Outlook to email PDFs out of Citrix. The problem is that in the MS Online situation, users will have to repeatedly have to type passwords every time they want to send an email.
Wouldn't it be fairly simple for the ONline team to create a SSO client that doesn't default to the cache button being selected? How hard would that be? It would fix most Citrix issues out there, I believe. - I agree that we have a HUGE problem regarding Terminal Server and Microsoft Online/Outlook 2007/SSO Client!
As I understand It's not supported to run Outlook 2007, cached mode, in a Terminal Server/RDC/Citrix environment
So the only solution to host the rich Outlook 2007 client is to have it use integrate with the MS Online SSO Client WITHOUT turning on cached mode.
I have myself been searching like a crazyman for a solution or at least in-depth technical info on the matter, in vain....
I would assume MAPI is out of the question and will not be concidered by Microsoft Online team.
Help us out!

- I am currently working with the Microsoft BPOS team and the outlook developers to see if this can be fixed.
Microsoft have admitted it is an issue and is putting alot of large possible BPOS customers off the solution.
The reasons MS would not allow cache mode on terminal servers is due to the IO overhead and the fact that by default the cache file is stored in the profile wich would then need to roam.
We have been able to force the cache file to be directed to a network location on out EMC datamove (Only fat client).
We are not working on a patch to enable the cache function and see what the performance issues are. Other issues have been noted over the MS Online Client and the amount of memory it uses. MS are enableing Federation service in Q3 next year i think which will mean this client is not needed.
I will keep you all posted I am currently working with the Microsoft BPOS team and the outlook developers to see if this can be fixed.

Thanks Andrew. I'm aware of the password synchronization feature that's coming. That might indeed solve the SSO client issue. The problem is, how do we provide Outlook 2007 (Outlook 2010 even when it's around) to work in uncached mode, and even if it will, how would performance be with RPC/HTTP(s) uncached in a Terminal Server/RDS environment?
So basically, I want my problem fixed, then I want to nag about the performance ;-)
Please Andrew, Microsoft and any of the billions on this earth, let's tackle and solve this problem- It works in Uncaches mode as standard and performance is shocking.
We are working on getting it to work in cache mode, however there is issues. But like i say, the Outlook developers are working on it. I am expecting a test patch some time on November.
Keep you posted - Andrew,
What you might want to look at working with is a "live archiving" option like Live Office's Personal archive to keep OST's low and refrence older or legacy items from with in the cloud in tehi web based outlook lug in.
