Microsoft Exchange Report

I faced a new issue today, don't know if anything breaks at Microsoft or any new thing roll out from there, the things is unable to check usage report properly as well as unable to export the email activity, Mailbox Usage etc report under report- exchange and other tabs as well in customer tenant.

I have Global Reader privilege but still facing this issue. Anyone faced this type of issue from today or before? If anyone knows about its pleas update your comment here.

    Hi,

    What you are describing is something admins occasionally see in Microsoft 365 reporting portals, and it is often caused by one of these areas rather than a permanent service break.

    Most common causes

    1. Reporting backend / temporary Microsoft issue

    Usage reports in the Microsoft 365 admin center depend on background reporting services. Sometimes:

    • Exchange usage reports fail to load
    • Export buttons stop responding
    • Data appears delayed
    • Only some tenants are affected

    This can happen during regional incidents or backend rollouts.

    2. Global Reader is not always enough for every report/export action

    Although Global Reader can view many reports, some report exports or detailed usage data may require additional roles depending on the workload and portal path.

    Common roles to validate:

    • Reports Reader
    • Usage Summary Reports Reader
    • Exchange Admin (sometimes useful for troubleshooting)
    • Global Admin

    3. Privacy / anonymized reports settings

    If your tenant has privacy settings enabled, some user-level reports may be limited.

    Check:

    Admin Center > Settings > Org Settings > Services > Reports

    There is a setting related to showing concealed user/group names in reports.

    4. Browser / session issue

    Very common.

    Try:

    • InPrivate / Incognito session
    • Different browser
    • Clear cache/cookies
    • Disable extensions
    • Try direct admin center login again

    5. Customer tenant delegated admin issue

    If you are accessing customer tenants through delegated admin / partner access, some reports can behave inconsistently compared with direct native tenant roles.

    What I would test immediately

    Check Service Health

    Microsoft 365 Admin Center:

    • Health
    • Service Health
    • Message Center

    Look for reports / admin portal / Exchange reporting advisories.

    Test another tenant

    If you manage multiple tenants and only one fails, likely tenant-specific.

    Test with higher privilege temporarily

    Use a Global Admin account to compare.

    Known Reality

    Microsoft reporting pages sometimes break before formal advisories are posted.

    Especially:

    • Export CSV buttons
    • Blank charts
    • Endless loading
    • Partial report data

    Recommended Workaround

    Use PowerShell / Graph reporting where possible.

    For Exchange mailbox statistics:

    Connect-ExchangeOnline Get-EXOMailboxStatistics

    For M365 usage reports:

    Microsoft Graph Reports API.

    My Likely Diagnosis

    Since you said today and multiple tabs are affected, I would suspect:

    1. Temporary Microsoft reporting issue
    2. Browser/session issue
    3. Role limitation in delegated customer tenant context

    Best reply to customer/users

    “We are currently validating a potential Microsoft 365 reporting portal issue affecting report visibility/export. Core services remain operational.”

    Final recommendation

    Check Service Health first. If no advisory appears, retry after some hours and test from another browser/account.

    Hope this helps.
