Office365: Using Exchange in Online Mode

Hello:

We are contemplating moving our in-house Exchange environment to Office365.  We are a Citrix XenApp shop and as such, will probably have to use Online Mode.  I've tested cached mode with the cache being on a network share.  It works reasonable well, but I haven't scaled it out.  I've read some whitepapers that explain why this isn't a good idea.

So, in testing Online mode, there is a detectable delay when switching emails or folders.  My question is this:  how do I test this accurately?  We have 1500 users and I don't know what the bandwidth requirement is.  Second to that, I read somewhere (can't find it) that you can exhaust your WAN IP's available ports, as each Outlook session will require multiple ports.

How can I test this to scale?  Are there other things I should be considering?

Thanks,

Dan

Outlook 2013 sounds pretty cool.

Our problem is that we are stuck with 2010.  We have some legacy apps that require it.
