Extremely disappointed! We endured more than two hours on the phone, experienced disconnections, and spent another hour trying to resolve our issue, only to discover what has already been posted about on this thread: To integrate our emails into the Outlook app, we're required to upgrade every company inbox to full Business Office 365 accounts.
Given our reliance on multiple Salesforce Outlook plugins, customer service ticketing, and shared templates, webmail is not a viable option for us. The cost to upgrade 5 emails is $143 per license, totaling an exorbitant $715! Despite being advised by GoDaddy that switching to Microsoft would necessitate this costly upgrade, we're at a point where further time investment is unjustifiable. It feels like a complete scam.
If you are reading this before you upgrade>> TRY TO INSTALL THE LEGACY OUTLOOK, add emails, then upgrade to new outlook. I have always had all email addresses in my Outlook., and still currently do - with only Email Essentials. The employee that kicked this off got a new laptop, reinstalled Office 365 on the laptop, and then it blocked her from adding the old email essentials account back in.
EDIT: It appears from other posts that MS covered their bases with the legacy install workaround. You'll just have to give them their pound of flesh.$$
