Unable to connect to database on Webdav with Android 8.0

[eleifhh]

Trying to open a database on an Office365 library results in an error. KeePass for Windows can open the database without any issues. Any help is appreciated!

Here is the log:

this indicates that this error comes from the authentication model used by Office 365: https://sharepoint.stackexchange.com/questions/165367/the-remote-server-returned-an-error-403-forbidden-when-accessing-office365-si

But maybe you can also try something like this: https://support.microsoft.com/en-us/help/2988732/403-sorry-access-denied-error-when-a-user-tries-to-sign-in-to-outlook

Philipp, thanks for your quick reply. I tried to understand your suggestions and links but am unsure what is needed to accomplish. Can you give me some hints or some reference how to connect to O365?
