There were lots of articles on the internet with complicated solutions, which did not work for me.

After disabling caching for my account, it still kept the OST file, even after forced deletion. Then I noticed some offline folders were being kept, like Inbox and Sent Items (right click -> Synchronization tab -> Offline folder contains…). When those were emptied, there was still something left in that OST file (<20MB). This is how you can disable offline folders altogether.Victor Zakharovdevopssoftwareexchange
