Não consigo aceder aos emails no Outlook.com nem aos ficheiros no OneDrive

Question

Olá, boa tarde,

O meu endereço de email é [Removido pela moderação] e estou a enfrentar um problema ao enviar ou receber mensagens. Recebi uma resposta de erro com o seguinte código:

"550 5.7.9 STOREDRV.Deliver; Recipient mailbox quarantined"

Pelo que pude entender, a minha caixa de correio foi colocada em quarentena, o que está a bloquear o processamento normal dos emails. Gostaria de saber o motivo desta quarentena e pedir ajuda para desbloquear ou restaurar o acesso.

Agradeço desde já a vossa atenção e aguardo instruções.

Com os melhores cumprimentos,

João

Hello João

Thank you for reaching out to Microsoft Q&A Support forum.

I can understand you are unable to access your emails in Outlook because an error message indicates that your mailbox has been quarantined. I am sorry to hear that, and I am willing to help.

Why a Mailbox Gets Quarantined:****

Malware or suspicious content**: If your mailbox was found to be sending or receiving emails with malicious attachments or links.

>Compromised account: If Microsoft detects unusual activity that suggests your account may have been hacked or misused.

>Spam or phishing: If your mailbox was used to send spam or phishing emails, even unintentionally.
**
What You Can Do:

Check for Suspicious Activity:**

Log into your Microsoft account and check:

>Recent activity: https://account.microsoft.com/security/

Look for unfamiliar logins or devices.

If anything looks suspicious, secure your account by changing your password and enabling two-factor authentication.

Try Webmail Access:

If you're using Outlook or another email app, try accessing your mailbox via the web:

For Outlook.com: https://outlook.live.com

This can help determine if the issue is with your local app or the mailbox itself.

Check Email Rules and Forwarding:

Sometimes malicious rules are added to compromised accounts:

Go to your email settings.

Look for Inbox rules, Forwarding, or Auto-responders.

Delete anything suspicious or unexpected.

Clear Outbox and Drafts:

Sometimes stuck or corrupted messages can trigger issues:

Open your email client (Outlook, webmail, etc.).

Delete any unsent messages in your Outbox or Drafts folder.

Restart the app and try sending a test message.

If you've tried all of the above and your mailbox is still quarantined or blocked, it's time to contact Microsoft Support:**

**Visit this website>> Contact Us - Microsoft Support
Sign in with your personal Microsoft account.
Enter your issue in the search box. For example, ''Outlook''

Click Get Help, then click Contact Support at the bottom of the page.
Under Products and services, select Microsoft 365 and Office.

Under Category, select ''Manage Outlook''

Click Confirm.
Select Chat with a support agent **in a web browser.
**
I hope these suggestions helps!

Thank you for your time and understanding.
