Q: How does DSAccess choose a DC/GC to talk to?
A: It really is discussed in great detail in the following white paper at http://www.microsoft.com/downloads/details.aspx?FamilyID=c976433f-f979-4745-b7a6-9d8446ef6409&DisplayLang=en . A good guideline to keep in mine is that the server will try to talk to those available in the site it belongs to and then other sites/domains. Best practice is to always have a GC for your domain in the same site as your Exchange server.
Q: At http://www.microsoft.com/exchange/techinfo/security/antispam.asp I read the following: “These user-maintained block and safe lists are shared from the clients to Exchange, where server-side filtering is conducted.” Does this mean that the lists are generated on the Exchange server?
A: Not really. This is actually a server side rule that is generated by the user. This is NOT taken away from the 32K limit that normal server side rules have.
Q: When sending a large attachment in cached mode I am seeing a larger amount of traffic than when I do this in online mode. Why is this?
A: When sending in cached mode, we first send the message, then the server notifies us that there is a new message in the “Sent Items” folder and we download that message again. Unfortunately we cannot change this in the current build of Outlook. But we did make some other changes that were a lot better than we used to work when we were using .osts. It used to be that when you read a message, replied to a message or forwarded a message we changed the icon on the message and that required another download because the message had changed. Now we don’t do that. We only tell the server to change the flag for the object so that the icon is different and don’t download the change.
