in SharePoint I have created a Folder Content type with additional columns (one of them a lookup column) using site columns and site Content types. I assigned this to a library so I can now use metadata on Folders. Also I added the columns to the Standard view. I connected to this library with harmon.ie for Outlook. At first, when creating a new Folder with metadata the lookup values etc. were also visible in the harmon.ie Panel in Outlook. In the next step I changed the view to have a grouping on this lookup column.
From this Moment the lookup values did not appear anymore in harmon.ie. Funny Thing is - when editing the values the metadata fields are shown and I can edit and save them. In this case the metadata is also saved in harmon.ie and the Folder is in the right Group.
I guess it's a bug? Tried it with Outlook 2016, latest harmon.ie Version, with SharePoint 2010 and also Office 365/SharePoint Online.
Any ideas?
Thanks and best regards Bernhard
