Microsoft Office has a general path length limitation of 250 characters. This affects any external application interacting with Office, not just AOS. Office can handle more than 250 characters in many cases, but Microsoft does not provide official support in these circumstances. These are problems that you might encounter if you use long paths:
- Office reports that a document cannot be registered and OLE linking is deactivated (due to the path length limitation in OLE)
- The browser plug-in does not open a document
Avoid deep folder structures and path lengths over 250 characters, or if you must use long path lengths, test extensively with Office before deploying to a production environment.
