Good day.

I have noticed that if I have started a Lync conversation with someone during the entire day that it stores multiple copies of the conversation in my Conversation history folder. Let me explain with an example.

I talked with John Doe from 8am-9am uninterrupted. It will store that convo into the history folder with a size of 100kb.

I come back to John around 10am and talked to him for another hour uninterrupted. Outlook will then combine the earlier conversation and append this convo to the bottom and save it in the history folder with a size of (100+ 70 = 170kb). However, if you look at the history folder, it will still save the first conversation (100kb) and have this new convo as well (170kb). It does not cleanup the first conversation.

The cycle continues throughout the day where I have multiple conversations with John and they get stored in multiple times without removing the old one. End result we get a potentially large # of conversations stored chewing up a lot of space.

I have been manually doing the cleanup of duplicate messages to free up space. This leads me to the question on whether if there is a cleanup mechanism or setting I need to enable so that I can avoid this manual work?

Your response(s) are greatly appreciated.

Hi All,

Found a third party software online and ran the executable and it looks to have done the cleanup. Apparently Microsoft Outlook Cleanup Conversation Folder could not perform the cleanup.

Hi,

Base on my test, the same result as you.

If I IM with another user and not close the IM windows, after the conversation history be saved, then go on IM with him, then this time, conversation history will save all information on the IM windows.

The workaround is close the IM windows after finishing the chat every time.
