Using Outlook for iOS for personal email and calendar management
I understand that all your accounts are listed in Outlook on your new iPhone, but only two circular account icons appear in the sidebar.

Please first update Microsoft Outlook from the App Store. Then open Outlook, tap your profile icon in the upper-left corner, select Settings, and check each account under Accounts.
For an affected account, select Reset Account if that option is available, then close and reopen Outlook. If the icon still does not appear, remove and re-add one affected account through Settings > Accounts > Add Account. Please avoid removing all accounts at once, especially if any use custom IMAP settings or work or school security requirements.
If the issue continues, contact Outlook Mobile Support from within the app by tapping your profile icon, the question mark icon, and Contact Outlook Mobile Support. This allows the support team to review the relevant app diagnostics.
