We installed the Harmon.ie personal plan (harmon.ie add-in for outlook on W10 pro laptops of similar brand/model) for some of our users. After supplying their O365 credentials and SP URL, all users of one of our office groups are able to see the SP document library in the harmon side bar in outlook, including the folders / document sets within that library.
However, in the sidebar only some users can actually click into the folder / document set and see the contents (ie individual files). Others can click but the contents of the folder is not shown (in fact nothing happens on double click).
The users are all part of the same O365 group and the entire group has edit permission level for that document library. Users that can not properly use the sidebar have access to the folder and documents using SP online.
Any ideas on the possible cause and ways to resolve? Thanks for any help!
Update: I looked into the error log (harmonie.log) and around the time the user clicked on a folder name in the add-in, the error logs lists numerous errors with similar headings (see below). The add-in 'hangs/stalls' for a couple of seconds, you can not highlight another folder and then it defreezes again. Lines from error log:
