What is IMAP, and Why Use It with Office 365?

IMAP (Internet Message Access Protocol) allows users to access their emails from multiple devices. Unlike POP3, which downloads and removes messages from the server, IMAP synchronizes emails across all platforms, ensuring that any action (like reading or deleting an email) is mirrored on all devices.

Benefits of Setting Up Office 365 IMAP:

1. Access from Anywhere: Read and manage emails from multiple devices, ensuring consistency across your phone, laptop, and tablet.
2. Real-Time Synchronization: Every action you perform is instantly reflected on all devices.
3. Data Security: Emails remain on the server, so there’s no risk of losing data if a device is lost or damaged.
