@claudioegj This error indicates a buffer overflow (/GS) or DEP exception. Can you provide more info on the OS and it's version (Win+R -> type 'winver'), the version of the Office package installed (also specify if it's x32 or x64), also describe the conditions, i.e. was it working before or it's a fresh installation... any updates installations recently, etc.?

Hello thank you very much for the answer, I use on windows server 2012 R2, I got this problem these days but I realized that the synchronization has not been done since February, there is no office installed on that server

@claudioegj Googling ucrtbase.dll + OneDrive, shows this problem has been encountered many times


The article below suggests uninstalling OneDrive and redownloading the latest version.

I tried to install old and updated versions but it doesn't work at all
