Frequently Asked Questions

Why do follow-up flags disappear in Outlook on the web?

This is a known synchronization bug in Microsoft 365 where refreshing the web page causes the application to fail to retrieve the flagged status from the server. Microsoft is currently investigating this sync issue.

Can the recipient see my follow-up flag in Outlook?

Normally, if you set a custom follow-up flag strictly for yourself, the recipient should not see it. However, due to a known glitch in certain Outlook versions, a flag intended only for the sender might incorrectly display for the recipient.

Will reinstalling Outlook fix the disappearing flags?

Reinstalling the app typically does not fix this specific issue, as it is related to an ongoing server-side synchronization bug with Microsoft 365. Updating to the latest version or submitting a feedback report is recommended.
