Syncing email on my Samsung Galaxy Ultra S 26 only allows me to choose the number of days to sync. It does not enable me to auto-sync continuously. It had worked previously but changed for some reason. What settings need to be changed?

    For Samsung Email, continuous syncing is controlled by the Sync schedule setting, not by the days of email to synchronize setting.

    Try these checks:

    1. Open the Samsung Email app and go to Settings.
    2. Tap the affected email account.
    3. Check whether the account was added as Exchange or as IMAP.
      • If it is IMAP, calendar and contacts will not sync, and the account may only offer limited sync behavior.
      • Remove the account and add it again as Exchange for Microsoft 365/Exchange accounts, or Outlook.com.
    4. In the account settings, make sure Sync Calendars and Sync Contacts are enabled if needed.
    5. Check the Sync schedule setting.
      • Set it to As Messages arrive for continuous syncing.
      • If it is set to Manual or another schedule, mail will not sync continuously.

    If this is a managed work or school device, an Intune policy can also control this behavior:

    • Sync schedule can be set by policy.
    • Contacts and Calendar sync can also be enabled or disabled by policy.
    • If those settings keep reverting, the device policy is likely enforcing them.

    If the account previously synced continuously and now does not, removing and re-adding it as Exchange is the main supported fix for Samsung Email.

    Hi Terry Duke,

    I understand how inconvenient it is when email stops arriving automatically after working normally before.

    As the AI-generated answer explained, “days to sync” only determines how much older email is stored on the phone, while automatic delivery of new messages is controlled by Email sync schedule. Please try the steps in that answer first, especially setting the sync schedule to As messages arrive, if that option is available.

    If the setting is already correct but the issue continues, Android may be restricting Samsung Email from running in the background. Please also check the following:

    • Go to Settings > Apps > Samsung Email > Battery and select Unrestricted.
    • Go to Settings > Battery > Background usage limits and make sure Samsung Email is not listed under Sleeping apps or Deep sleeping apps.
    • Under Settings > Apps > Samsung Email > Mobile data, enable Allow background data usage.
    • Temporarily turn off Power saving mode, then send a test email while the app is closed.

    If the issue continues, please confirm whether you are using the Samsung Email app or the Microsoft Outlook app, and whether the account is Outlook.com, Microsoft 365, or another email provider. The available sync options can differ depending on the app and account type.

    As Samsung Email and the phone’s battery-management settings are Samsung features, Samsung Support may also be able to check whether a recent app or system update changed the background-sync behavior. Thank you so much for your understanding.
