IMAP is a popular email protocol that allows users to access and manage their email accounts across multiple devices while keeping messages synchronized.

That means you can have your email on different devices and still have access to everything in your email account. However, you might encounter issues where your folders fail to synchronize correctly, which can lead to missing emails, duplicated folders or inconsistencies in your email settings.

You can temporarily disable your antivirus or firewall software and check if your the IMAP synchronization problem persists.

Sometimes, using all kinds of your antivirus for your system can interfere with some functions on Outlook. If disabling your antivirus or firewall makes your Outlook function effectively, you should reconfigure it to grant full access to Outlook.

Then configure your IMAP account within the new profile and reconfirm the status of the synchronization.
