IMAP/POP Setup for Faculty/Staff GVSU mail

These instructions are for devices that do not support a direct connection to Microsoft Exchange.

It should be noted that use of IMAP, and especially POP, should be rare and avoided whenever possible. 

IMAP/POP will only synchronize email to your device. Your calendar, contacts, and task lists will not be synced to your device.  

*IMAP - If your device has the option, we recommend that you set how many days email is locally stored. This will conserve space on your device

**POP (not recommended)  Downloads the content of your email to your device potentially consuming a great deal of space and removing it from your online Outlook account.

We recommended using the web client at for most devices.

Available By Request

POP and IMAP are disabled for Microsoft 365 accounts by default but is available by request. Send an email to [email protected] or fill out an Application Access Request form to start your request.

Mobile Device POP and IMAP Clients

The use of POP and IMAP to connect to a email address should be rare, as most modern mobile email apps support Microsoft Exchange. However, if you encounter a mobile device that is using the POP or IMAP protocol to send and receive mail after a mailbox is moved to Exchange Online, attempt the following steps:


Remove and re-add the account:

  1. Ensure you are disconnected from any WiFi networks (Apple performs an SSL verification, and I've found the results can vary depending on the WiFi network. Disabling WiFi temporarily and using cellular data is a good work around for getting consistent results).
  2. Open Settings
  3. Scroll down to the Mail setting
  4. Open Mail
  5. Click Accounts
  6. Click the POP or IMAP account to be remove
  7. Click Delete Account
    • After deletion, you will be brought back to the Accounts page
  8. Click Add Account
  9. Click Other
  10. Click Add Email Account
  11. Enter Name, Email, Password, and Description information
  12. Enter the incoming and outgoing mail server information based on the table above. NOTE: username and password are required for both incoming and outgoing servers
  13. Click Save



Remove and re-add the account:

  1. Swipe down from the top of the screen
  2. Select the gear icon to access Settings
  3. Click Accounts and Backup
  4. Click Accounts
  5. Select the account you'd like to delete
  6. Click Remove Account
  7. At the confirmation pop-up click Remove Account
  8. Navigate back to the Accounts screen
  9. Click Add Account
  10. Select POP3 or IMAP
  11. Enter email address and click Manual Setup
  12. Select POP3 or IMAP
  13. Enter your network password
  14. Enter your userid and password, and the incoming server information:
    1. Click Next once complete
  15. Enter your userid and password, and the outgoing server information:
    1. Click Next once complete
  16. Select your preferred account options (notifications and sync frequency) and click Next
  17. Enter your display name and click Next


macOS or Windows POP and IMAP Clients

The use of POP and IMAP clients on desktops and laptops is also quite rare, but there are some computers that require the use of third-party email clients. There are dozens of third-party email clients that support POP and IMAP, but below are troubleshooting steps for one of the most popular clients:


Remove and re-add the account:

  1. Right-click the account name/email address from the left-hand navigation menu
  2. Click Settings
  3. Click Account Actions
  4. Click Remove Account
  5. Confirm you'd like to remove the account by clicking Remove
  6. Click OK
  7. Click Account Actions
  8. Click Add Mail Account...
  9. Enter your name, email address, and network password
  10. Click Continue
  11. Select IMAP or POP3 and click Done
  12. Click Finish
