Greetings, You did not mention your EXCHANGE and client versions? I support EXCHANGE 2010.x with 1300 users so that is my caveat.
Regarding performance issues, unless you have some server issues, I have not heard about the folder location being a performance issue. I would suggest you determine if your clients are using ONLINE or CACHED mode just so you know. There can be site specific setups on why you are using either/both configurations. As others noted, if you have Retention Tags, then you have to know where they are applied. At my site, we apply to the INBOX (and some other standard folders) , and that is where our users create sub folders. But YMMV if this is not an issue. Again, I am not aware of a folder performance issue with any of this, and more of an operational and support issue managing your EXCHANGE environment. Hope this helps or please post any questions.

There's a debate going on in my group about the best practice for placing Outlook subfolders. One group is saying it doesn't matter, so let users continue creating subfolders under the Inbox. While one group argues that Inbox subfolders do affect Outlook performance, so they said subfolders must be placed under the root of the maillbox. So, I'd like to heard both sides of the arguments on this list. I personally don't think it's an issue where it's placed. Thanks.
