Check Microsoft’s Service Health Status first because current user reports indicate that some Outlook users—including users around Chicago—may be experiencing problems, although there is no confirmed Chicago-specific Microsoft outage bulletin in the available information. ^1^
Determine whether this is an outage or a mailbox problem
- Open Microsoft’s Service Health Status site:
https://status.cloud.microsoft/m365/referrer=serviceStatusRedirect
Microsoft directs Outlook.com users there for current service availability. ^2^
- Open Outlook.com in a browser rather than relying only on the Outlook app.
- If new messages appear on the web, the mailbox is working and the installed app has a synchronization problem.
- If the web inbox also remains unchanged, send a message to yourself. Failure to send or receive there points to a service or mailbox-level issue.
- Try another connection, such as mobile data instead of Wi-Fi. If Outlook works there, the problem is associated with the original network rather than a regional Outlook outage.
Downdetector currently reflects user-submitted problem reports, but it is a non-Microsoft service and does not constitute official confirmation. ^1^
If Microsoft reports no incident
Check these Outlook.com mailbox conditions:
- Storage: If Microsoft cloud storage is full, Outlook.com cannot send or receive mail. Messages sent while storage is full are rejected to the sender and cannot later be recovered.
- Inbox view: Select Filter → Sort → Date so recent messages appear first.
- Check the Other and Junk Email folders.
- Review Settings for forwarding and inbox rules that could redirect messages.
- Check whether the Microsoft account is temporarily blocked because of unusual sign-in activity. ^3^
The published Outlook.com known-issues page does not identify a current Chicago-specific mail-delivery incident. ^2^
If mail still does not arrive
In Outlook.com, select Help, describe the send/receive problem, complete the suggested troubleshooting, and then select Still need help? → Yes to contact Outlook.com support. ^3^
