Hi,
I don't know why but my Online Address Book is not fully sync with Exchange on Android.
It's first time this happen.
The sync procedure ends well, no error, but I can't find a lot of contact.
One example:
Cate**** Cerra*****
cate**************@yahoo.it
338 4** 4**4
appears on my address book on zoho mail but not appears in my addres book on Android.
The same happens also to another my account, synced with another smartphone (android 6.0).
