Unable to mark as not junk

If you are unable to click "mark as not junk" for an email that has been incorrectly classified as junk, it may be due to several reasons:

1. Client-Side Filtering: If the Outlook Junk Email Filter is set to No automatic filtering, it will not attempt to classify messages as spam, but it still uses the safelist collection to move messages to the Junk Email folder. This means that the filtering is not being actively managed, which might affect your ability to mark messages as not junk.
2. Spam Filtering Policies: The email may have been classified as junk based on Microsoft 365's spam filtering policies. If the message is classified as spam or high confidence spam, the actions taken on these messages depend on the anti-spam policy settings. You can configure these settings to allow for better management of such misclassifications.
3. Permissions and Settings: Ensure that your account has the necessary permissions to report and manage junk email settings. Sometimes, organizational policies may restrict certain actions.
4. Technical Issues: There could be a temporary technical issue with the Outlook service that is preventing you from marking the message as not junk. In such cases, trying again later or refreshing your browser may help.

If you continue to experience issues, consider reviewing your junk email settings or contacting your IT support for further assistance.

Hello,

It could be the spam filtering automatically tagging the mails as junk, there are some things that can set off the filter such as links in the emails and embedded pictures that can cause false positives. After you're able to find the email in the junk folder make sure to add the sender to your safe senders list so that everything they send will be received by your email.

Hope this helps,
