Today I see the index paused, but the number of element indexed still increase, slowly now. When I delete for example 50 spam emails, I see how the total number of the index elements decrease in the same amount.
I've been replaying some emails and after a while, if I search in outlook, the emails are found, so definetelly those are being indexing despite the"paused index" message.
But I can tell that the indexing of those files are too slow. It doens't find the emails until few minutes, and my index database ended yesterday, so I don't think it has too many things to add.
In resume, this doens't work properly and I don't see Microsoft giving a solution soon.
I also have problems with the search of content inside PDF files even I installed a ifilter and enabled seach for content too. I tried several ifilters and I did always a index rebuild. It is frustrating.
