Hi,
unfortunately Offline Folder support is not working well with Windows Home Server, since there are difficulties due to the special methods Windows Home Server uses to store data in shared folders (by using tombstones in the original share, which are pointing to one of the potential duplicated copies. So it could be, that sometimes only the tombstones are visible offline, which means the real data is not accessible.
In the past users reported also issues with Office files, here the files were only accessible offline after copying them off to a real local folder.
So the statement remains, it is not supported.
Ifd you still wish to synchronize certain folders, tools like
MS SyncToy can be helpful.
Best greetings from Germany
