Moved all my users to GMail.
Can find no redeeming feature in either Outlook or Exchange at all, and certainly not in OWA.
For those whose inbox was precious, I just used GSSMO (be careful, GSMMO or something is a similarly named tool!) and imported their mailbox into GMail.
The only blocker was a couple of people who use desktop programs that use MAPI to send their mail... but Google Sync for Outlook sorts that out - they have an install of Outlook that syncs to their GMail and it sends the mail from GMail.
The administration, the spam-filtering, the access, the compatibility, the calendar... so much better with GMail and Google Calendar.
If I was a millionaire starting my own business, I'd just buy GSuite. So many problems solved so very simply in any modern browser.
