Using Outlook for Android for personal email and calendar management
That is not my experience. I just tried at least 6 email apps on my phone when the HUB stopped working to evaluate alternatives, and every single one worked. This is on my Samsung S23 Ultra. I haven't found one that does everything HUB+ does, but they all authenticated and worked as expected.
So you can confirm You managed to add MS activesync accounts into Your S23 without problems? Where did you added the accounts? Under Settings-Accounts-Add Account-Exchange? Because I can also add any IMAP or POP account as well into phone but I can't add any ActiveSync accounts to get addresses and calendar synced.
