When trying to access a shared clendar in Exchange Online from Outlook 2013 it is very slow to open / create items. We have tried numerous things to improve performance without luck, eg.

  • check anti virus isn't causing problems
  • turning off hardware accelaration
  • turn off caching for shared folders
  • etc.

We have discovered today that during the wait for an item to load (which can take in excess of 20 seconds) if we perform a "Reconnect" from the "Connection Status" option of the systray icon then the item will open as soon as the reconnect occurs.

 

Can anybody advise what we can do to improve performance?

I should also point out that accessing other mail items in a shared mailbox is not nearly as slow as accessing calendar items
