Hi, I have configured WebDAV with Apache2 on a Ubuntu machine using the mods dav, dav_fs and dav_lock.
Connecting to WebDAV folders works fine, from both Windows and Linux clients. Even writing, modifying and deleting documents is possible. Then only problem is when I try to save documents from Microsoft Word 2016. Word first creates the file on the server, but then following error appears: There has been a network or file permission error. The network connection may be lost https://support.microsoft.com/en-us/help/291156/you-receive-a-there-has-been-a-network-or-file-permission-error--the-n (Solutions there don't help) error.log: Could not DELETE /pinakos/admin/66AEE86C.tmp due to a failed precondition (e.g. locks).
