Future optimisation

Plan attachment optimisation with the right evidence.

Large attachments can consume storage repeatedly across mailboxes. MailboxVitals surfaces the evidence administrators need to assess that pressure and plan safe, governed next steps.

Current focus: MailboxVitals provides metadata-led assessment, evidence and recommendations. Attachment offloading is a planned optimisation workflow designed around destination-readiness checks, administrator review and explicit approval.

Future admin-controlled workflow

Use assessment evidence to identify suitable large attachment candidates.
Check whether SharePoint or another approved destination is suitable.
Present recommended actions for admin review and approval.
Move approved files to the chosen storage location.
Replace the original attachment with a small link/stub file.
Keep audit evidence and before-and-after reporting.

Opportunity signals

Use evidence to plan—not automate—the next step.

These anonymised demo report visuals illustrate how MailboxVitals can surface storage and attachment opportunity signals, then frame recommendations for administrator consideration.
