Hi, David
At this moment, it's meaningfulness to choose a point for standing by.
Have you contacted the Apple's support? The reason why we asked you to contact their side since you're not using O365 applications.
And the product which design by Apple's team, so please give a attempt to figure out the reason the service is not available for accessing shared mailbox on the iOS application.
If they mentioned that it's a change from the protocol with Microsoft and Outlook, then we can refer you to the Microsoft Feedback portal.
If it's the change of the iOS Mail application, you should contact to iOS mail application.
Thanks for your time and your understanding would be highly appreciated.
Regards,
Alex.
Hi, Alex.
This is always easiest way to send off to another company support team but the problem starts with Microsoft.
Microsoft turned off basic authentication on exchange online.
Now no one no matter what email client uses can't access shared mailbox (except of course by Outlook app).
Nevermind what client I use, could you please tell if it's possible to connect shared mailbox with IMAP right now or we are waiting to all vendors all over the world will adapt to new MS regulations and use OAuth2 for a shared mailboxes?
Please do not recommend me using Outlook mobile app. There are many reasons why not to use it. For me it is a ****, don't have many config options, it's slow, searching mails or contacts is a mess, hangs up many times. Sorry but there are many other mail clients better. Please let me know if you see any workaround of that situation. That's not the first time MS wants to make all people happier.
