Email filter

On the Inbox page, click on the gear icon in the upper right corner, then on "Email Settings".  On the landing page under Mail you will see "Filter rules".  Click on that and follow the prompts to set up a filter.

I did doesn't seem to have any effect.  I want anything with onmicrosoft.com to go to trash

Have you tried removing the "*" from the "Sender/From Contains" condition? I don't think it's necessary and may actually be preventing the condition from matching the sender email address.

I think maybe the mail filter only works with mail going to your inbox and not your spam folder is this possible?

Correct. Sorry for not catching that before. Email filters only operate on messages delivered to the the Inbox and only as they are being delivered. Filters can't be used to remove messages from the Spam folder. You could make your filter work by turning off Comcast's spam filtering, but that's probably not a good idea.

If the sender's address is always the same you could try whitelisting it so mail would be placed in the Inbox instead of the Spam folder. Then your filter should be able to grab it and delete it. See https://forums.xfinity.com/conversations/email/how-to-prevent-email-from-going-to-the-spam-folder/602dafffc5375f08cd1ec7b9. But that will only work if the "From" address is the same for each "onmicrosoft" message, since the whitelisting mechanism doesn't allow wildcards.

I read that the Spam folder is automatically emptied every 7 days. Does that really happen?

Has anyone tried contacting Microsoft directly, about the “@onMicrosoft.com” Spam problem?

Good morning,

As previously noted, the email filters only work on emails being sent to the inbox. Unfortunately, the emails coming from onmicrosoft are going to be simply emails hosted by Microsoft services and Comcast would be unable to prevent any unsavory sending habits from their domain. To add, you read correctly, more information can be found here: https://www.xfinity.com/support/articles/set-email-deletion-settings 

I read that the Spam folder is automatically emptied every 7 days. ...

In addition to the information in the "Email Deletion Settings" article, Email Expert @Latoque and Employee @XfinityGabrielS have posted:

• Spam is stored for 7 days or 5,000 messages, whichever comes first
• Trash is stored for 14 days or 5,000 messages, whichever comes first
• Messages deleted from Trash are kept for 30 days or 15,000 messages, whichever comes first. These can be recovered (see https://connect.xfinity.com/appsuite/apps/faq/index.html#recoverEmail) and do not count against the 10GB mailbox limit
• Messages in the remaining folders are kept indefinitely
• If the 10GB mailbox limit is exceeded, new messages are not accepted
• Users cannot change these settings

Perhaps I am mistaken that these emails are coming from a Microsoft server here are a few of the full email addresses what do you think? If it is from a Microsoft server I will contact them and complain

Email deletion settings program Xfinity Connect to remove old messages from your Spam and Trash folders automatically. These settings apply to the date of the email; the settings are listed below.

• Spam: 7 days

  • Only flagged Spam will be deleted after 7 days

Unfortunately, I know of no documentation of the word "flagged". I would guess it means "mail Comcast determined to be spam", but that's only a guess. It may mean "Comcast determined" or "customer clicked webmail 'Mark as spam' icon".

Maybe @XfinityCSAEmail will clear this up for us.

Most (95%) of my daily spam comes from the .onmicrosoft.com domain.  I sent the abuse team multiple examples of the garbage ID and Host names, and sent

detailed header info to the Microsoft CDOC Case Management Team ( [Edited: "Personal Information"]) for their investigation.

Is there a way to manually run an email filter after you've edited it?

Is there a way to manually run an email filter after you've edited it?

Sorry, no. Email filters only operate on messages delivered to the the Inbox, and only as they are being delivered, so filters can't be tested until an email that matches the filter conditions arrives in the Inbox.

... Only flagged Spam will be deleted after 7 days

@XfinityCSAEmail: That statement (found in https://www.xfinity.com/support/articles/set-email-deletion-settings) appears to be incorrect. My experience is that ALL messages in the webmail Spam folder are deleted after 7 days, whether they have been "flagged" or not.
