I would find it highly useful for not only us but our customers, to enable password sync but leave exchange attributes editable in the 365 portal for users who wish not to have any exchange products on premise.
Almost like filter out all mail related attributes from the sync, soft match users via another method and enable people to edit mail attributes from the 365 ECP
many customers we have are migrating from IMAP systems to 365. but then get most upset with us when they want DirSync and realize they either need to use unsupported tools to edit user email settings such as ADSI edit, or install exchange EMC onsite.. when
the whole point of moving to 365 was to get rid of dependency on on premise installations.
I wondered if this is something Microsoft acknowledge and will look into resolving for SMB's with a small server base (one or two physical boxes) who want Dirsync but without an onprem requirement for exchange.
Thanks

Also, just to make clear, most our customers would be happy with something as simple as extending the Schema and then a dll addin to add a "365" tab to ADDS. just like the old acctinfo.dll - basically anything to make 365 with Dirsync but no on prem EMC a supported scenario, which looking at all the previous questions and responses Microsoft must see is something people want and need?
