Microsoft outage: Are your personal photos and documents on cloud storage safe? Can you lose everything stored in Outlook and OneDrive?

Microsoft's global outage has left millions of users struggling to access Outlook, Teams and other Microsoft 365 services, which raises concerns about what happens to personal emails, photographs and documents of people that are stored online. With OneDrive also appearing on the list of affected services, users may be wondering whether their data is at risk or if everything saved in the cloud could disappear during an outage.

However, the immediate point of concern for people is the access to their files rather than a permanent loss. Microsoft has not stated or indicated that this global disruption has resulted in customer data being deleted or destroyed. The company has also said it has no indication that the incident was caused by a cyberattack.

Why are Outlook and OneDrive services facing problems?

According to Microsoft's service updates, the disruption began with Exchange Online which is the infrastructure that supports Outlook's email services. A problem related to servers and their ability to handle secure connections had affected users who were trying to access their mailboxes.


The issue then spread to other Microsoft 365 services, including Teams, SharePoint Online, Copilot and OneDrive. Microsoft said that some servers became unexpectedly unavailable, shifting additional load onto the remaining infrastructure and making recovery more difficult.

While OneDrive was on the list of affected services during this outage, Microsoft noted that direct access to stored SharePoint and OneDrive files remained mostly intact for many users, with disruptions primarily stemming from authentication timeouts and features reliant on Exchange Online.

The company also cautioned that some servers became unresponsive again after traffic was restored, forcing engineers to continue testing fixes and monitoring their stability.

Can you lose your Outlook emails and OneDrive files?

A service outage does not automatically mean that the data stored on it has been lost.

Cloud storage services such as OneDrive store files on remote servers rather than simply just relying only on a user's computer or phone. According to Cloudflare, cloud providers use redundant storage systems, which involve maintaining multiple copies of data to reduce the risk of permanent loss if individual servers or hardware fail.

Microsoft support also says its services have multiple physically redundant copies of customer data. Its OneDrive, SharePoint and Exchange infrastructure is designed to maintain data availability through replicated copies.

This means that if you are not able to open an email, photograph or document during the outage that does not necessarily mean it has been deleted or lost forever. Users may have to wait until the affected services are fully restored to access their information again.

What if your files are stored only in the cloud?

OneDrive's Files On-Demand feature allows users to see files in File Explorer without downloading them onto their computers. Such files are marked with a blue cloud icon and require an internet connection to open.

Files marked with a green check are locally available, while those marked with a green circle and white check are downloaded and set to remain available on the device even without an internet connection.

Users who want access to important documents during internet or cloud-service disruptions can choose the 'Always keep on this device' option. This downloads the selected files to the computer.

How can you recover deleted emails and files?

Microsoft provides recovery options for accidentally deleted content. OneDrive personal users can restore deleted files from the online Recycle Bin for up to 30 days. For work or school accounts, the retention period can extend to 93 days.

Outlook also has a recovery option for deleted messages. Users can first check the Deleted Items folder and, if necessary, look in the Recoverable Items folder for messages that have been removed from Deleted Items.

These options are useful safeguards against accidental deletion, although they are different from protection against a temporary service outage.

For particularly important photographs, documents and personal records, maintaining an additional copy on an external drive or another storage service can give an extra layer of protection. A cloud outage may temporarily lock users out of their data, but it does not automatically mean they have lost everything stored in Outlook or OneDrive.
