# Email

> Configure a team inbox and follow up on email requests.

Every Flow team has an email inbox. A team administrator can change its address before sharing it
with requesters.

<Warning>
  **Connect Directory Sync before accepting email from new requesters.** Open **Settings → Identity**
  and complete [Directory Sync setup](/setup/administration/identity-and-directory#set-up-identity).
  Single sign-on (SSO) alone is not enough. Connecting Slack or Microsoft Teams does not enable email access.
</Warning>

Invited Flow members with a known email can use email without Directory Sync. Flow always checks
email authentication, including for existing members.

## Configure the inbox

<Steps>
  <Step title="Open Flow Teams settings.">
    Open **Settings → Flow Teams**.
  </Step>

  <Step title="Open the team's Flow settings.">
    Expand the team and open **Flow settings**.
  </Step>

  <Step title="Edit the address.">
    Under **Email**, edit the **Team email local part** if needed.
  </Step>

  <Step title="Save.">
    Select **Save changes**, or **Save address** to reserve an automatically provided address.
  </Step>
</Steps>

If Flow displays a reserved address instead of an editable field, contact Flow support to change
it. The page also shows the default email signature.

## Following up by email

Requesters can email the team inbox to start a request. They should reply in the existing thread to
add more information.

Operators reply from **Conversations → Requester chat**. Select email under **Communication Channel**
when it is available. If the reply area offers attachments, select email before adding them.

One incoming email can include up to 25 attachments. Files that start a new conversation can be up
to 10 MB each. Files in a reply to an existing request use the configured upload limit, which is 25
MB by default. Flow keeps the email comment when a file cannot be added and shows a separate notice
in the conversation. See [Request tracking](/setup/request-tracking#browser-chat-file-support)
for the supported formats. The browser count and size limits on that page apply only when you upload
through Flow.
Flow can read worksheet cells and saved formula results from an unprotected XLSX attachment up to
10 MB. A larger file may remain attached to the request without being readable in the conversation.
Dense workbooks may show only part of each worksheet; Flow marks omitted cells.
