Hi I am wondering if

Connect to Exchange server using HTTP

would improve performance the user opens 4-5 other mailbox's calenders.
will Connect to Exchange server using HTTP cause problems - will it make it faster for her - she is complaining about hour glass/circle very slow - any way to fix - it s 1-2 2 users on a 20mb connection - im hoping i dont need a riverbed or like? - any other solution - im not keen on cached mode as she opens 3-4 other mailboxes - and with that cached mode does not work well. - thanks

    Sorry, what exactly do you mean by "Connect to Exchange using HTTP"?  Do you mean switch this user over to webmail?  Or do you mean using http instead of https?  (I wouldn't recommend the latter)

    A comment on not wanting this user to use Cached Mode - that might be the answer to your speed problems.  What problems do you see when this user uses Cached Mode?

    I would recommend you switch to RPC over HTTPs and enable cached mode. You can exclude the addidtion mailboxes from caching, which will eliminate the issues you are seeing. To do that, go to File- Account Settings - Change - More Settings - Advanced - Uncheck "Download shared folders"

    You should see a big performance improvement just enabling caching alone.

    thanks how do i do this - switch to RPC over HTTPs? - where are settings for this?

    Accepted Solution

    i think this was due to the sttic arp - not working/resolving accross router - as expected!

    ill need a static arp in her switch /subnet.

    the static arp is due to the NLB/windows - for the 2 x cas servers.
