Quite often I get my whole inbox displaying each document with the words “index:colicon1:9998” instead of the Subject, and index:colicon:177" instead of the Date.If I go to another view and back to the inbox, it all displays properly.
I HAVE moved some columns around, if that helps anyone to debug this.
Subject: Same issue triggered by deleting
Myself and another user here have been getting this occurring when deleting messages from the inbox, rather than moving to folders, in an inbox with rearranged columns. We run 8.0.2 FP1 on Windows XP. Switching views and back corrects the problem.

Subject: Same issue here
I am having the same issue with my mail and that of someone else. What we have in common is that both of us have moved our columns around.Changing views and going back seems to resolve the issue.
In my case this is triggered when I move items to folders.
Any assistance would be greatly appreciated.
