Excel Upload Failed (Save a Copy)

Hi there! I intend to use Cryptomator for file encryption, however, under Cryptomator 1.8 an Excel file residing in a container cannot be edited and saved to the vault without resorting to make a copy, defeating Cryptomators purpose.
Microsoft Excel (Version 2208 Build 16.0.15601.20590) 64-bit shows an error “Upload Failed” in the status bar with the option to “Save a copy” or “Discard Changes”.
Is there any workaround for this issue? I saw posts about editing the hosts file, however, this has already happened and does not help.

Hey and welcome to the Cryptomator Community :slightly_smiling_face:,

I highly assume you’re using Dropbox as cloud? We have just found a bug that matches your description that is specific to the combination of Windows + Microsoft Office + Dropbox, see Dropbox + Word: Failing to save document · Issue #2880 · cryptomator/cryptomator · GitHub for more information.
