If yes, then you are not alone, since many users go through this issue. Thus, to bail you out of this problem, we prepared this expert guide consisting of the prominent causes, tried-and-tested solutions, and some expert tips for a seamless experience to resolve the issue.

Why Are IMAP Folders Not Showing in Outlook?

• In various IMAP accounts, the user has to manually subscribe to the mailboxes to make them display in Outlook.
• If the configured IMAP account’s root folder path is incorrect, at that time as well some common folders such as Inbox, Sent, Drafts, etc. do not show in Outlook.
• Another common reason behind IMAP folders missing in Outlook can be the disabled synchronization of the new folder structure.
• Adding incorrect IMAP incoming credentials such as port, authentication, and so on also prohibits IMAP synchronization and therefore leads to the IMAP folders not displaying in Outlook error.
• Weak internet connection, system malfunction, and outdated Outlook version are other reasons behind this issue.
• Apart from this, if the IMAP email server is not responding due to any server downtime or other technical issue, then users face the folders not showing in Outlook problem.
• Last but not least, when the IMAP account’s mailboxes are too large, it slows down the synchronization process and makes the user feel that some folders are missing from Outlook.

Important Note: Since all of these are manual settings, they are prone to error and therefore lead to data loss or manipulation. So, make sure to backup IMAP server emails using a certified, simple, and fast utility. Apart from this, you can also move your data to another platform if not satisfied with Outlook’s performance.
