Unable to delete emails from outlook mailbox

I am also unable to delete any emails and it says in 11 days, I will be unable to receive any emails. I have not been able to send any emails for quite some time now. I've had to use another email address with another company. It also keeps saying I need to buy more storage because my onedrive is full, which must be incorrect as I rarely use my one drive. So rarely, I don't even know what could possibly be on there. I save everything on my hardware. Also when I try to see what could possibly be on my one drive, there is no option to access it. I haven't been able to find a direct customer support number or a live chat. For such a big company, this is beyond ridiculous. I'm hoping someone will reach out and reply to me now. None of the options below have worked either. My housemate is also experiencing the exact same issue.

How do I disable Outlook cash mode?

My inbox is full and I cant delete emails by pressing shift deletei cant delete emails

Why can't I delete my read emails

Hi Rama,

I have this issue now with New Outlook in my Personal Account.

I have tried to follow 1. but I can't see Cached Exchange Mode. 2. & 3. have not worked.

I generally "Report" the Junk mail that I receive as it is mostly phishing messages.

Please provide me instructions on how to rectify this issue, which has only started happening in the last few days.

P.S. FYI, I set up a new Outlook email address as an experiment to see how long it would be before it started to receive spam/phishing/junk messages. I haven't used the email anywhere on the Internet, not even to send messages. Within 72 hours, the spam started to arrive. How can this be? Is there a security issue within Microsoft?

Thank you for your support on these issues.

Hi Rama D,

Good day.

Hope you are doing well you for posting in Microsoft Community.

To help us narrow down the issue

1. Check if your Outlook is in Cached Exchange Mode. If it is, try disabling it and then try deleting the emails again.
2. Check if you have any rules set up in Outlook that might be preventing the emails from being deleted. If you do, try disabling them and then try deleting the emails again.
3. Try deleting the emails from the Outlook Web App (OWA) instead of the Outlook client application. This will help you determine if the issue is with the client application or the server.

If you are using an Outlook desktop client, please kindly open Outlook in safe mode (Press Windows + R keys > type outlook.exe /safe > click OK) to check a particular situation or result scenario

Please also ask an Office 365 admin to sign in Office 356 admin center, navigate to Exchange admin center > Recipients > Mailbox > choose the affected email account and click Edit > mailbox features > Litigation hold, check if your organization admin enabled Litigation hold on these mailboxes. If Litigation Hold is enabled, the users will be unable to delete emails in their accounts.

I hope this helps let me know if this is contrary to what you need, I would still be helpful to answer more of your questions.

Best Regards
