Hello Kaviya Rajendiran,

Thanks for update. From our end, we had check this case with our consult team and there is no service incidence reported for this issue. Further as no retention policy is set for this sites in your organization, it’s hard to found the reason of file disappearance.

So at this point, we would like to suggest you to run content search tool from Office 365 security and compliance center to check if any files are saved on the server or not. If you see all the data from the result, it may be an connection issue between server and application. Before run content search tool, you need to assign permission to user mailbox and then you can run it.

Kindly refer this article to run Content Search : https://docs.microsoft.com/en-us/microsoft-365/compliance/content-searc

Hello Kaviya Rajendiran,

Thanks for update. Since there is no information found in Audit log, it might be file was disappeared because of Retention policy set in your organization.

So we would like to suggest you to kindly check if is there any retention policy is set for your SharePoint site or Teams:

• To do so: login to O365 with global Admin account -> Open security and compliance center -> Information governance -> Retention -> check Policy settings if any policy is set up SharePoint site or Teams. If policy is set up, remove it or edit it according to your requirement and check the result.
