In my Exchange 2010 environment, when users (mostly on Outlook 2013) when they go to type in a new e-mail and type a recipient and click "Check names", or if they click "Address Book", if begins lagging and having problems connecting to the Exchange server.
I believe I've got AD/Sites configured properly and DC's in the proper locations.
What else do I need to check? What's entailed when invoking Check Name or Address List that would cause Outlook to start hanging with connecting to Exchange (trying to retrieve data from exchange server)?

Best practices analyzer didn't find anything strange but 1 critical issue of the "MaxPageSize is set too High" which is set at 10,000, I'm told my other admins due to LDAP query needs. I'm not sure if that's going to affect the issues are having with Outlook, though.
