I also have a problem with the Outlook plugin...
The outlook plugin loads a blank screen in the Todoist frame. If I wait 4-5 minutes (doing nothing), it partially loads the Todoist web page login screen without images or styles.
If I click in that frame and reload it by hitting F5, it loads the web version of my project/task page (with the projects on the left and the tasks on the right) and I have to scroll frame to see the relevant portions of the screen.
I can provide screen captures if you need them. This has been happening for the past few days -- I am a new user, so I have only been using it that long.
I am on Win7 64bit and IE9 (I cannot upgrade to IE10 due to business restrictions). The plugin version is 220.127.116.11
Following your answers to other users in the past few days, I have done the following:
Cleared the IE cache
Uninstalled the plugin
Rebooted the computer
Cleared the IE cache again
Downloaded the latest version of the plugin and installed again
Can you help?
