Current limitation: a message filed in multiple places (like when using Send & File) only appear in one place in Verse Mobile. Fix this. See this technote of known limitations:
Mail documents only appear in one folder
"The IBM Notes Client allows a single mail document to be in multiple folders or views, but the mail application on the device only allows a single mail document in a single folder. Therefore, the device will only show the mail document in the most recent folder. If you are using the IBM Notes Client Send and File feature or a rule with a Copy to Folder action, the mail message will only appear in one folder on the device even though it may appear in multiple folders/views in the IBM Notes client. Sent and Drafts are special in that they are always the most recent if the document appears in either one of them."
