possible danger emptying the recycle bin
 

As far I can tell, the following are the case - most good - one dangerous:

1. delete any item sends it to recycle bin .... good

2. shift delete any item to permanently delete - but first a pop up asks do you want to delete any sync'ed outlook items or files, where if the checkbox is checked that equals "yes I do"..... good

3. delete any item in the recycle bin (NOT empty the recycle bin) provides the same pop up choice as in 2. above.... good

4. Empty the Recycle bin pops up "are you sure you want to permanently delete all links..." .... dangerous!!!

In point 4, If the pop up "do you want to delete any sync'ed outlook items or files", was PREVIOUSLY checked "yes I do" - then when you empty the recycle bin, you are essentially potentially unknowingly deleting any sync'ed Outlook Items, and/or Files!!!

Therefore, when performing the operation Empty the Recycle Bin, a pop up needs to also confirm whether or not you want to permanently and non reversibly delete synced Files or Outlook Items...

Yes, it should also include that option on Empty Recycle Bin. This will be fixed in the next release. Also note that UR moves synced items to the Deleted Items folder (Outlook) or Recycle Bin (Explorer) and doesn't permanently delete them.
