Office365: Using Exchange in Online Mode

Posted on 2013-06-11
Last Modified: 2013-10-26

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?

Outlook 2013 sounds pretty cool.

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

So this is good information to have, but I really need help finding a solution for testing this to scale.  Any suggestions?
