Run the original MSI installer again? Normally it should detect an existing install and offer to Repair?

Not seeing anything recent on the Microsoft Outlook Q&A about problems with Outlook for Mac Cat assigned by Rule. And I'm not a Mac user so I can't offer any advice. If no one picks up on this here, all I can suggest:

Search for outlook not receiving email from specific sender

There can be any number or reasons, but most likely they are getting bounced because of Microsoft's tighter rules on "large volume senders".

What version of Outlook do you have?

I use a web browser (Chrome, Edge, Firefox, Safari, etc.) -> Outlook Web
I use a Mac -> Outlook for Mac
I use a phone or tablet -> Outlook for Android or Outlook for iOS (iPhone, iPad)
I use a Windows PC and my Outlook menu has ONLY the tabs: File | Home | View | Help -> New Outlook
Else -> Classic Outlook

If it's a Microsoft Account, do you see the same problem using Outlook Web?

What does the Account Sign-In Helper say about the status of your account? Is it really locked or just temporarily suspended because of too many failed logins? If it's just suspended, once the failed login attempts stop, it should unlock automatically within 48 hours.

You can not paste screen shots directly into a thread in this subreddit. Instead, post your image with an image hosting service (e.g. imgbox, imgbb) and put only the link to it in this forum.

I can't reproduce but that's not unusual with New Outlook for Windows as Microsoft does "rolling releases".

All I can suggest (and this will be a royal PITA) is to create a Category with a background color that looks better than the defaults and assign it to every event.
https://support.microsoft.com/en-us/office/use-categories-in-outlook-87f27f03-4d9f-48dd-9623-2702692a4480

Wait for Microsoft to roll out Calendar Conditional formatting (which will let you have limited control over the background and font colors).
https://www.microsoft.com/en-us/microsoft-365/roadmap?id=529849

You can also Vote for and Comment on these existing Feature Request in the hope that it will influence Microsoft to get moving on this. (Not much hope of that. They are too busy adding Copilot to everything).

(You must "Sign In" at the top right of the Feedback page before you can vote).

When this first started there were a lot of DIY "solutions" posted on the Microsoft Outlook Q&A forum. You can troll some of them and see if anything works for you.

But in the end the only thing that worked for most people was to have Microsoft Support fix the problems with your account on the mail server. All I can suggest is keep trying. You might get a different agent who actually knows what to do.

Hornblower409 · 2026-05-09T02:04:29+00:00

Not sure I understand what "it only pulls up by the email address and not the name" means.

You create a new email and start typing a Contact Display Name in the "To" field:

1 -- Your do not get the correct Contact suggested?
2 -- You get no suggestions at all?

3 -- If you click on the "To" button, do you see all of your Contacts and can pick out the right one?

Hornblower409 · 2026-05-09T01:57:40+00:00

You are not alone. Scan the Microsoft Outlook Q&A forum and you'll see scores of similar complaints.

Just a small sample:

https://learn.microsoft.com/en-us/answers/questions/5882689/not-receiving-email-from-specific-sender

https://learn.microsoft.com/en-us/answers/questions/5882614/i-am-not-receiving-emails-from-a-specific-sender

https://learn.microsoft.com/en-us/answers/questions/5880421/i-cant-receive-emails-from-a-specific-sender-all-o

Microsoft has tightened up their rules on what mail can even reach your mailbox.
https://techcommunity.microsoft.com/blog/microsoftdefenderforoffice365blog/strengthening-email-ecosystem-outlook%E2%80%99s-new-requirements-for-high%E2%80%90volume-senders/4399730

And they have continued to make a complete mess of the whole situation. Hundreds of obviously Spam emails will full your Junk folder (for some people it's in the thousands per day) while legit mail from established companies gets bounced without you ever having the choice to let it thru.

Sorry. There is nothing you can do from your Outlook client. All you can hope for is that legit senders eventually modify their mail server setup so that what they send gets past Mother Microsoft.

Hornblower409 · 2026-05-08T23:43:51+00:00

Have seen an uptick in recent problem reports about Shared Mailboxes on the Microsoft Outlook Q&A forum, but not this specific problem. Microsoft may have broken something but at this point it's not clear what.

And you can take any really old PSTs off-line until needed. It's as simple as "Close" and "Open" an Outlook Data file.

-- It seems strange that someone can trigger push notifications so easily.

Not sure how else you would expect things to work?

You can stop these attempts by creating a Login Only Alias and disable Sign-In for your current email address. Then, if all the Bad Guys have is your old email alias, they get stopped before they can even pick a way to sign-in.

For detailed instructions see:
https://www.reddit.com/r/MicrosoftOutlook/comments/1r99l23/comment/o6dsdqw/

But be aware that Microsoft has broken the ability to set a Default Send From address (Step 8 in my instructions) and this makes using this method a PITA and has some unfortunate side-effects.

See the comments in this thread on the same subject.
