We are using outlook 2010 and exchange 2010. We work in online mode, not cache and use Windows XP. We did not migrate from another version. I now have two people within my corporation that cannot view their tasks properly in their to do bar. I thought perhaps it was the client, so I reinstalled, no go. I tried a different pc all together and that did not work. I tried the outlook /cleanviews /resettodobar /cleanviews. I created a new profile but this did not work.
I'm not too sure what to try next. The first person it happened to I thought was a fluke but now that I have two people, I am afraid it might happen more. The weird thing is that if you add a new task, the task list shows properly however when you close the client and reopen, the list is empty again. If you play around with the view of the sort order that sometimes works too. But nothing seems to fix it.
