Missing incoming emails over multiple days – possible mail delivery failure

Hello,

I am experiencing a serious email delivery issue with my Outlook.com account: [mod: PII redacted]@hotmail.de

Over the last 3–4 days, multiple important emails have not arrived in my inbox. This includes emails from:

• The U.S. Embassy in Frankfurt • My mobile network provider

These emails were expected, time-sensitive, and confirmed as sent by the senders.

I have already checked: • Junk Email folder • Deleted Items • Focused Inbox (disabled) • Inbox rules (none deleting or forwarding mail) • Blocked senders list • Outlook Web and Outlook Desktop

The emails are missing entirely and do not appear anywhere in my mailbox.

This suggests a possible server-side filtering, throttling, or delivery failure on the Outlook.com infrastructure.

This issue is causing real problems, as I rely on this account for official and legal communications.

I kindly request: • A delivery trace for the last 4 days • Confirmation whether emails were blocked, quarantined, or dropped • Immediate resolution or escalation

Please treat this as urgent.

Kind regards, Clarence Johnson

    Hi Clarence, I understand how critical it is when important emails don’t show up, especially for official matters. Based on what you’ve described, this usually happens when the sender’s mail server can’t complete delivery or the messages are flagged by Outlook’s security filters before reaching your mailbox. Sometimes this is due to SPF/DKIM issues on the sender’s side or temporary throttling if the system suspects spam. Let’s start with a few checks: can you confirm if the senders received any bounce-back or non-delivery reports? Also, have you tried searching your mailbox using the exact sender address or subject keywords? If nothing appears, I can help escalate for a message trace to see if the emails were blocked or dropped. Do you also use any third-party email apps or forwarding settings that might intercept mail?
