Hi Microsoft Support, we are in Timor-Leste and our organization's Outlook and Exchange Online are still completely down. Do you have any updated ETA for full restoration in our region? Thank you.

Hello Zé,

I understand that your organisation in Timor-Leste is still unable to access Outlook and Exchange Online, and you would like to know when full service will be restored.

Microsoft is aware of the ongoing service disruption (MO1550821), affecting Exchange Online and other Microsoft 365 services across multiple regions. Microsoft's engineering teams are actively working to restore the affected services.

Unfortunately, no confirmed ETA for full restoration, including in Timor-Leste, has been provided yet.

For the latest updates, please ask your organisation's Microsoft 365 administrator to check incident MO1550821 in the Service Health portal: https://admin.cloud.microsoft/?source=applauncher#/servicehealth/:/alerts/MO1550821

Hi Fahim-Nz,

Thanks for the update on incident MO1550821.

I'm the Global Administrator for our organization, and I'm keeping an eye on the Service Health portal from my end. Because this outage is heavily disrupting our daily work here in Timor-Leste, I'd really appreciate it if you could keep me in the loop as soon as there's any progress or an estimated time for a fix.

Best,

Hello Zé,

Thank you for following up. I understand that the ongoing Outlook and Exchange Online disruption is affecting your organisation's daily operations in Timor-Leste.

According to the latest update on incident MO1550821, service availability is improving. Email queues have been significantly reduced and are approaching normal levels. However, some users may still experience intermittent access issues or delayed email delivery.

Microsoft has implemented additional mitigation measures and is restoring the remaining affected infrastructure. The incident is not yet fully resolved, and recovery efforts to restore the remaining affected infrastructure are continuing

Could you please check whether users in your organisation can now access Outlook and send and receive emails successfully? This will help establish whether services have been restored for your organisation or if issues are still occurring.

You can also monitor incident MO1550821 through the https://admin.cloud.microsoft/?source=applauncher#/servicehealth/:/alerts/MO1550821 for further updates.
