几乎所有的账户设置失败都归结为四件事之一：
- 你的提供商需要一个不同的密码。 许多提供商不再在邮件应用中接受你通常的密码，而是发放一个单独的密码。
- IMAP 已被关闭。 某些提供商自带邮件应用访问被禁用，有的在你一段时间不使用时会再次关闭。
- IMAP 需要额外收费，或不提供。 少数提供商仅在付费计划中允许邮件应用，或根本不提供。
- 这是工作地址，雇主决定可以连接什么。

Your provider isn't listed?
Work through these four, in order, they cover most of what's left:
- Sign in with your email address and password first. Leave Allow BlueMail to auto-detect the server details of your account ticked. If that works, nothing else here applies.
- Check for an app password. Search your provider's help for "app password", "application-specific password" or "password for mail programs". If they issue one, use it instead of your normal password.
- Check IMAP is switched on in your provider's webmail settings, usually under a heading like POP3/IMAP, External access, or Mail apps.
- Get the server details from your provider's own support page and enter them by hand. See Configuring your account manually.
Still stuck? If the app showed Setup could not finish, that error has its own page, Setup Could Not Finish (Error 3017). Otherwise Can't Add My Account has the full checklist and the page for each specific error message.
Adding a particular kind of account
- What provider should I choose from the list? if you are unsure which entry matches your address.
- Setting up iCloud Mail on Android, iPhone and desktop.
- Adding Gmail with manual IMAP and an app password, when the browser sign-in is not an option.
- Adding a shared or delegated Office 365 mailbox.
- Configuring an account for incoming mail only.
- Adding more than one account, and how many is sensible.
- Fixing an issue on the Google console if you manage your own OAuth setup.
