A Microsoft file hosting and synchronization service.
Hi, Krupička Lukáš
Thanks for posting in the community.
The shared folder in OneDrive becomes .Internet shortcut is indeed a long-standing problem. Recently, more users may be affected due to some updates.
We are glad that your efforts have brought some good results, which may help other users refer to this method to reduce the impact on work and life.
According to your description, you seem to copy the path (cloud address) of the last opened file through OneDrive in the Office application, and then map the address as a network folder and access it through Explorer.
We are on the same side as the users and we are also waiting for this issue to be resolved. We welcome any suggestions that may help users solve their problems.
Thank you again for your careful observation and hard work!
