Hi, I've been having problems with the EMSX on our 10 Exchange 2010 SP1 servers. 1. Users often see "Microsoft Outlook is trying to retrieve data from the Microsoft Exchange server..." I've seen that this is usually an issue with 4.2 and Windows 2008 R2, I've followed the KB article and while it's got better I'm still getting the issue 2. I've told EMSX not to scan all files (selecting the default extension list from all the different sections in the Settings Panel, but I can still see under Statistics that it's constantly scanning all the *.tmp files, I've even added an exclusion to C:\Windows\Temp\*.tmp and still it scans them 3. In event viewer I keep getting error 9843: I've looked on Google and can't find any reference to this issue.
