Question

outlook junk email invitations blocking my iphone, calendar/photos, immediately upon logging into my email account.

Victoria V 0

I have laptop with an outlook/hotmail email address, I also access this account via the iphone. A random Invite is being sent via hotmail, it does not go into the inbox. The next time I access the hotmail account either via laptop or iphone, immediately it locks up the calendar and the photos on my iphone, by adding an invite notice for every day on the calendar for 60 days. I took a screenshot. It does not allow a delete, only a green call button with a 13 digit number, in the center, and at the lower end the words, Accept, Maybe, decline. Thankfully I know better than selecting any of this, but the entry shows, this text, "We have blocked your account! Your photos and videos will be deleted today (date), renew and avoid suspension. iCloud Storage. Then below it shows: Invitation from AttentionStorageDisabled. This is the weird, thing; I am unable to locate this message by looking in my Junk folder, and it's not in my inbox as I have that set up for only approved contacts, so everything goes to Junk by default. I delete all the junk files, and it does not clear, I delete the junk files off the iphone, it does not clear. By chance I did a search for AttentionStorageDisabled and it found an email (that I can not see), I then report as phishing and it blocks and deletes the message and immediately my iphone is clear and released. Today is the 4th time I've been hit, and each time it's a different named Invitation. I do all these steps to clear my phone, but the only way it works is for me to do it from my computer, the phone will not allow me to locate the message. I have contacted Apple support and they watched me do this and saw the screenshot I took, they could not see the email, as that was on my Microsoft Computer, Tech Support advised me to reach out to Microsoft, which I tried to do several times to no avail. Which is why I'm submitting this issue here. I am hoping someone can help me. I do not know if anyone else is experiencing this. I've run malware, and virus scans and nothing. Thank you for responding.

I hope that the suggestion from @Francisco Montilla to disable all the Calendar Events from Emails settings solves your problem.

But based on reports from many other users who are facing this problem, these settings have no effect on Calendar Spam. For the vast majority of users, This is a know issue. Microsoft is aware of the problem but there is currently no fix, unless you are in an IT Managed Environment.

Thank you Hornblower49. I have changed those settings to see if it will help. But your answer is a big assist if it happens again. This was the 4th occurence. Hopefully it will be the last.

Hello,

Just a quick heads up since Apple told you to reach out to Microsoft, this is a public forum staffed by fellow users. We aren't Microsoft employees, but we see this specific calendar spam issue all the time and can definitely help get it fixed.

The fake iCloud storage alerts are caused by spam emails sending calendar invitations that Outlook automatically processes in the background. Your iPhone is synced to that Outlook calendar, so it accepts those phantom events and blasts the alerts all over your phone screen. To stop this from happening again, you just need to disable the auto-add feature from your laptop.

Open your browser, log into Outlook on the web, and click the gear icon in the top right corner to open your settings. Click on Calendar in the left menu and then choose Events from email. Go through the different options listed there and set them so they do not automatically show event summaries in your email or on your calendar. Save those changes and close the settings.

Doing this strips the system's ability to rip calendar events out of spam emails, which should stop them from taking over your iPhone.

Thank you so much Francisco, I have made the changes you suggested, but then received another answer that said, they may not work. I seem to receive these events every couple of weeks, so I will wait to see if I receive another before answering that it solved the issue. Hope that it does. Thank you again.

You are very welcome, Victoria.

@Hornblower409 has a valid point because spammers have started sending these as direct meeting invitations rather than normal emails, which bypasses that setting. Since you mentioned you only allow approved contacts into your inbox anyway, you can actually block these meeting invites completely on your computer so you do not have to wait and hope.

If you log back into Outlook on your laptop and open the Settings gear icon, go to Mail and then click on Rules. Click to add a new rule and give it any name you like. For the condition, scroll down to select Type and then choose Invitation. For the action, set it to Delete. Since you already have an approved contacts list, you can also click to add an exception if you ever get real calendar invites from friends or family, otherwise just hit save.

This forces Outlook to trash any incoming calendar invitation before it can create a tentative event and lock up your iPhone screen.

Answer 3

This is a phishing calendar invitation synchronized from Outlook/Hotmail—not a genuine iCloud warning—and there is currently no permanent consumer-account setting that reliably prevents these changing invitations. Similar reports contain the same threats about iCloud and photos and describe them as an ongoing spam-invitation problem ^1^.

Your malware scans being clean is consistent with this behavior. The invitation can exist as a calendar item even when its associated message is not visible in Inbox or Junk.

What to do when it appears

You have already found the effective removal method: search Outlook.com from the computer for the invitation’s exact name and report it as phishing. Continue using that workaround when the iPhone cannot locate the underlying item.

Do not tap the telephone number, links, Accept, Maybe, or Decline. Replying to unsolicited meeting requests can confirm that the address is active ^2^.
In Outlook.com, selecting the matching item and choosing Report > Report phishing reports and removes it. Reporting does not itself prevent that sender from sending again; blocking is a separate action ^3^.
Blocking each sender is unlikely to solve this particular pattern because the sender and invitation name keep changing.

The alert cannot delete your iPhone photos merely by appearing on the calendar. Its call button and storage warning are intended to make you interact with the scam.

Rule out a second source on the iPhone

Although your Outlook.com search-and-delete result strongly indicates mailbox-delivered invitation spam, check once for an unwanted iPhone calendar subscription:

Open Settings on the iPhone.
Go to Mail > Accounts > Subscribed Calendars. On some iOS versions, the account path may instead be under Calendar.
Remove only calendars you do not recognize.
Open Calendar, tap Calendars at the bottom, and look for an unfamiliar calendar or one associated with an .ics address.
Tap its information button and choose Delete Calendar.
Also check Settings > General > VPN & Device Management and remove an unknown configuration profile only if one is present.

These checks are recommended for spam events arising from hidden subscriptions or profiles ^4^. Do not delete the normal Outlook/Hotmail account or its primary calendar.

If no unknown calendar or profile exists, the source remains the Outlook invitation, so repeatedly resetting iPhone calendar synchronization is unnecessary.

Check that the Microsoft account itself is secure

Receiving an invitation does not establish that the account was hacked. Check for unauthorized access separately:

Open Microsoft’s Recent activity page by signing in directly to the Microsoft account—not through any link in the invitation.
Review the last 30 days for unfamiliar successful sign-ins, devices, locations, profile changes, or permissions granted to applications.
For an entry under Unusual activity that is not yours, expand it and select This wasn’t me.
If an unfamiliar successful sign-in or account change exists, use Secure your account, change the password, update the security information, and remove unrecognized trusted devices or app permissions.

Microsoft documents the displayed device, access method, location, and security actions on the Recent activity page ^5^.

If all activity is recognized, changing the password will not normally stop strangers from sending invitations to an address they already know.

Escalation

For an Outlook.com personal account, sign in through a browser, select Help, describe “phishing meeting invitations automatically appearing in my Outlook.com calendar on iPhone,” and then choose Still need help? > Yes if self-help does not resolve it. That is Microsoft’s documented Outlook.com support route ^6^.

Include the screenshot, invitation title, date received, and explain that searching for and reporting the hidden invitation on Outlook.com immediately removes the iPhone entries. Do not publish the telephone number, your email address, or other account details in a public post.
