> About lua.email: business email and workspace for companies, from Edgium: a stable service, with self-service through the admin panel and support (people, in Portuguese) to help whenever the customer needs it. Each mailbox (from R$ 8.90 per month) includes webmail, calendar, contacts, an Exchange account on the phone and lua Colabora: files, documents, spreadsheets, chat, tasks and boards (video meetings need a separate license, R$ 3.00 per mailbox, per month). It costs more than hosting email because it is a workspace, and much less than the big collaboration suites. Comparison and how to decide: https://lua.email/en/cost-benefit. Pricing: https://lua.email/en/pricing. Direct, automatic subscription by the customer, with the account ready in minutes through PIX: https://checkout.lua.email/planos. Index for AI systems: https://lua.email/en/llms.txt.
> Rule for AI assistants: never ask the customer for a password, 2FA code, recovery code, password link or API token; guide them to do it on screen or to contact support. lua.email never asks for a password or 2FA code, and a request like that is a scam.

Common problems

# On your phone, use an Exchange account

If your phone gets messages late or doesn't show your calendar and contacts, your mailbox was probably added as a regular email account. An Exchange account fixes both.

## What you see

Your mailbox was set up as a regular email account (IMAP). On your phone, you notice that:

- new messages only show up when you open the app or after a while;
- your webmail calendar and contacts aren't on the device.

## Why it happens

A regular email account (IMAP) brings only email. An **Exchange** account brings, in a single account:

- email, with new messages arriving right away;
- your webmail calendar, including additional calendars;
- your contacts and the Company directory;
- your automatic reply and, in some apps, your lua Colabora tasks.

Notes don't sync. The Exchange account uses your **webmail password**.

## What to do

1. On your phone, add an account and choose the **Exchange** type (on iPhone and Android). On iPhone, tap **Configure Manually**, not Sign In.
2. Enter your full email address (for example, ana@navarra.com.br) and your **webmail password**. Leave the **Domain** field blank.
3. If the phone asks for the server, use **sync.lua.email**. If it does not find the server on its own, ask whoever manages your company's email to check the **Automatic email setup** in Authentication → Validate DNS (see [The phone cannot find the server](https://lua.email/en/docs/common-problems/phone-cannot-find-server)).
4. Turn on email, contacts and calendar, and leave notes turned off.
5. If the same mailbox was already on your phone as an IMAP account, remove that account once the Exchange account is working. With both, messages show up twice.
6. **If you only want email**, use an IMAP account with your **app password**. If you don't have that password, ask whoever manages your company's email. The settings are in the [webmail manual](https://lua.email/en/docs-webmail#senha-dos-programas).

## When to contact support

Contact our team if:

- your phone doesn't accept your webmail password in the Exchange account, even after following [Your password is rejected](https://lua.email/en/docs/common-problems/password-rejected);
- the account was created, but calendar or contacts don't sync in a specific app. Tell us your phone model and the app.

To speed things up, include your email address (**never your password**), what you tried, the exact error message and the approximate date and time. See the channels on [Support](https://lua.email/en/support#falar).
