- Device & OS
- not provided
- Scenario
- Switching Microsoft 365 resellers resulted in account or licensing changes.
- Observed behavior
- Emails and Office files appear to be missing or inaccessible even though changing resellers should leave tenant data intact.
Gather your Microsoft 365 tenant details, affected account email addresses, and the names of both your previous and current resellers before reaching out to support.
Contact Microsoft Support via the Microsoft 365 Admin Center
The most effective way to recover lost tenant data caused by reseller changes is to have Microsoft's backend team investigate your licensing history and tenant status.
Changing a reseller should generally not require data migration because the data remains securely in the Microsoft 365 tenant. If files or emails disappear, it is usually tied to a temporary lapse in active licensing or backend provisioning errors.
Sign in to the Microsoft 365 admin center using an account with Global Administrator privileges.
Look at the bottom right corner of the admin center dashboard and click on the 'Help and Support' icon.
Type your specific problem, such as 'missing emails after changing reseller', into the text box and press Enter to view initial automated suggestions.
Select the 'Contact Support' button to create a new service ticket. Provide your tenant details, affected accounts, and relevant reseller information so Microsoft can investigate mailbox availability and DNS configuration.

Frequently Asked Questions
Does changing a Microsoft 365 reseller delete my data?
No, changing a reseller simply updates your billing and licensing partner. Your actual tenant data, including Outlook emails and OneDrive files, remains intact on Microsoft's servers during the transition.
Why are my users missing their Office files after the switch?
Missing files usually result from temporary licensing gaps during the transition. If user licenses are removed by the old reseller and not immediately reapplied by the new one, their mailboxes and OneDrive data may become temporarily inaccessible.
How long does Microsoft retain data if a license is unassigned?
Microsoft typically retains user data for 30 days after a license is removed. If the new reseller assigns a valid license within this 30-day grace period, the data is usually restored automatically to the user.
Can my new reseller help recover the missing emails?
Yes, your new Microsoft 365 reseller has administrative access to your tenant and can open an escalated support ticket with Microsoft on your behalf to investigate data loss or licensing misconfigurations.
