Microsoft Exchange Online incident: what it means for Cirros users

Microsoft has reported a live incident on Exchange Online (Microsoft 365 reference EX1550543) that is stopping some users from reaching their mailboxes through Outlook on the web, Outlook desktop, mobile and other methods. On-premises mail flow to and from Exchange Online can also be affected. Microsoft is applying fixes and expanding capacity to restore service.

Because Cirros scan-to-email and inbound email print rely on your Microsoft mailboxes, these may be delayed or unavailable while Microsoft works on it. Cirros printing itself is not affected.

Your Cirros printing is working normally

Sending documents to Cirros, holding them securely in the cloud and releasing them at the device all work as usual. If you normally email a document in to print and cannot right now, print from the Cirros client instead, or sign in to the Cirros web upload with your email and PIN / Passcode, upload the document, and release it at the printer.

What may be delayed

Scan to email. Cirros still sends your scans, but if your mailbox is on Exchange Online you may not be able to open them until Microsoft restores access. Queued scans will arrive once it does.
Large scan download links. A large scan arrives as a link that expires after about 72 hours and once it is opened. If a link lapses during the incident, simply scan the document again afterwards.
Email print. If you send from an Exchange Online mailbox you may be unable to submit print jobs by email. Use the Cirros client or the Cirros web upload instead.
Sign-in passcodes and MFA codes by email. If you sign in with a one-time passcode or a multi-factor authentication code sent to your email, or you are waiting on a new or reset Cirros PIN / Passcode by email, it may not arrive while Exchange Online is down.

What to do now

Carry on printing with the Cirros client or the web upload as normal.
Hold any non-urgent scan-to-email until Microsoft confirms recovery.
Follow Microsoft's progress on the Microsoft 365 status page. Your IT team can also track reference EX1550543 in the Microsoft 365 admin centre under Service Health.

This is a Microsoft incident, not a Cirros issue

The way Cirros sends your email is not part of this incident; the disruption is within Microsoft Exchange Online, at the mailbox end. None of your documents or Cirros data are affected. We are monitoring Microsoft's updates and will update this notice if anything changes.
