I segregate my customer contacts in sub folders to contacts. One folder for each customer. It does cause problems. This Outook for Android isn't syncing properly. I added a new contact in a "Vendors" sub folder and for some reason it synced yet there are other contacts in other sub folders that don't sync. I haven't figure it out. Strange little program. Even then once it is in Outlook it need to sync to Android contacts which it doesn't seem to be doing either. Any ideas on what I might be missing? Anyone else find this Outlook for Android not to be all together there?
