How to Fix Outlook Flag Display and Missing Follow-Up Options for IMAP
Question details
The user is experiencing missing follow-up flags or limited flag options when using an IMAP account in Outlook, particularly noticing feature differences between New and Classic Outlook.

- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Trying to set specific follow-up dates, custom flags, or reminders for emails using an IMAP account.
- Observed behavior
- Follow-up timing options (like Today, Tomorrow, Custom) are missing or flags do not display correctly for IMAP accounts, and PST import features are limited in New Outlook.
Before troubleshooting, verify whether you are currently using Classic Outlook or the New Outlook for Windows, as feature availability for IMAP accounts varies significantly between the two versions.
Revert to Classic Outlook for Full IMAP Features
Classic Outlook provides more robust support for IMAP features, including custom follow-up flags and PST management, which are currently restricted or missing in New Outlook.
The New Outlook is still undergoing development and currently lacks certain advanced IMAP features, including specific date flags and full PST file support. Switching back to the classic version restores these capabilities instantly.
Look for the 'New Outlook' toggle switch located in the top right corner of the New Outlook application window.
Click the toggle to switch it to the off position.
A prompt will appear asking for feedback or confirmation. Confirm that you want to switch back to Classic Outlook.
Allow the application to restart. Once Classic Outlook opens, right-click an email in your IMAP account to verify that the standard flag and follow-up date options are restored.

Report Missing Features to Microsoft via Feedback
Since New Outlook is actively being updated, submitting feedback directly helps Microsoft prioritize missing IMAP flag features and PST import support.

Frequently Asked Questions
Why can I only flag IMAP emails without a specific follow-up date?
Due to strict IMAP protocol limitations in certain versions of Outlook, you can only apply a basic follow-up flag to an item. Setting specific dates (like Today or Tomorrow) or custom reminders is fully supported for Exchange or POP3 accounts, but often restricted for IMAP.
Will PST import support be added to New Outlook?
Yes, Microsoft has indicated that PST file support and expanded features for New Outlook are actively being developed and will likely be introduced or expanded in a future software update.
How can I create a custom reminder for an IMAP email if flags do not work?
A common workaround in Classic Outlook is to click and drag the email to your Tasks or Calendar icon located at the bottom left of the navigation pane. This creates a dedicated task or appointment containing the email body, allowing you to set specific reminders and dates.
