How often does microsoft outlook check for new mail

Microsoft Outlook's frequency of checking for new mail depends on several factors, including the version of Outlook, the type of account you're using (e.g., Exchange, IMAP, POP3), and your system settings. Here are some general guidelines:

Outlook 2016 and later:

• For Exchange accounts: Outlook checks for new mail every 30 seconds by default. You can adjust this interval in the "Account Settings" dialog box under "Advanced" > "Schedule an automatic send/receive every [X] minutes".
• For IMAP and POP3 accounts: Outlook checks for new mail every 10 minutes by default. You can adjust this interval in the "Account Settings" dialog box under "Advanced" > "Schedule an automatic send/receive every [X] minutes".

Outlook 2013 and earlier:

• For Exchange accounts: Outlook checks for new mail every 1-2 minutes by default.
• For IMAP and POP3 accounts: Outlook checks for new mail every 10-15 minutes by default.

Outlook Web App (OWA):

• OWA checks for new mail every 1-2 minutes by default.

Mobile apps:

• Microsoft Outlook mobile apps (iOS and Android) typically check for new mail every 1-5 minutes, depending on the app's settings and your device's connectivity.

Other factors that can affect Outlook's mail checking frequency:

• Your system's network connectivity: If your system is not connected to the internet, Outlook will not be able to check for new mail.
• Your account's settings: Some accounts, like Exchange accounts, may have specific settings that control the frequency of mail checking.
• Your system's power settings: If your system is set to sleep or hibernate, Outlook may not be able to check for new mail.

Keep in mind that these are general guidelines, and the actual frequency of mail checking may vary depending on your specific situation.
