Hi,

We updated to Sharepoint 2013 (from 2010) late last year and as part of the update had hoped to use Onedrive for Business to help us sync documents back to Sharepoint across our business. Due to multiple issues with Onedrive we abandoned this approach as it was buggy and unreliable to say the least.

One of the many bugs we encountered were that a number of users started receiving errors when attempting to open Office documents from Sharepoint stating "Incompatible Office products are installed on your system....". Initially this seemed to be caused by a Windows/Onedrive Update back in Feb/March. Removing the update worked for a period of time, then the error returned (even without the update installed).

At this point the only solution appeared to be removing Onedrive for Business completely, which had worked up until now.

I now have two users so far who are encountering the exact same issue once again when opening Office documents from Sharepoint. The temporary fix is to end task msosync.exe and perhaps a more permanent solution will be to prevent mosync.exe from running at all. My concern is that this will break some of the functionality between MS Office (2013 Professional Plus) and Sharepoint - opening/saving/checking in and out/etc.

Please can someone confirm whether:

a) disabling msosync will cause Office and Sharepoint functionality to break

b) there is an alternative more appropriate fix for this issue

I have encountered these issues running Windows 7 Pro, Windows 7 Home and Windows 8.1 Home so far. Thanks for any help offered.
