i have the following problem happening only with Office365 files. Once they have been stored in the vault, they cannot be overwritten. This only happens when trying to store out of the application. Moving (and owerwrite) with Windows Explorer works.
Looking with Explorer into the folder, there is a .tmp file that has not been renamed to the original name (but has the right content if renamed manually).
Windows 10 Pro 22H2 Build 19045.5011
Cryptomator 1.14.0
Office 365 18.2409.1301.0
