Using classic Outlook for Windows in business environments
For an on-premises Exchange account in classic Outlook, the most relevant next step is to create a new Outlook profile from Control Panel > Mail instead of relying on the in-app account flow.
- Exit Outlook.
- Open Control Panel and select Mail.
- Select Show Profiles > Add.
- Enter a name for the new profile and select OK.
- In the account setup wizard, add the user’s email account and complete the wizard.
- Back in Mail, select Always use this profile and choose the new profile.
If Outlook still cannot create the profile, a documented cause for profile creation failures is cached Microsoft Entra broker account data. In that case:
- Delete all files from:
%LOCALAPPDATA%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AC\TokenBroker\Accounts - Restart Windows.
- Re-create the Outlook profile.
If the mailbox had been migrated from on-premises Exchange Server to Exchange Online, Outlook profile setup can also fail when all local Autodiscover options are disabled and connected experiences are also disabled. In that scenario, Autodiscover has no available path to retrieve account settings.
Manual setup is not supported for Microsoft 365 or Exchange Server accounts in classic Outlook unless POP or IMAP is being used.
