01
Test Microsoft 365 in the browser
Confirm the account can authenticate and that the mailbox is accessible. If web sign-in fails, stop treating this as an Outlook-profile problem.

When Outlook cannot create the profile at all.
A profile rebuild only helps if Outlook can actually reach and configure the Microsoft 365 mailbox.Prove identity, connectivity, Office state, and Autodiscover before repeating the wizard.
02
Verify the workstation can reach Microsoft services
Rule out local internet instability before chasing Office. A connection drop can make every later profile test misleading.
03
Check Office and saved identity state
Confirm Office is signed into the intended work account. Stale cached credentials or the wrong Office identity can keep profile creation pointed in the wrong direction.
04
Use Autodiscover evidence
If repeated profile creation fails, test the automatic configuration path and document the result instead of changing random registry values.
Know when the problem has moved beyond a normal rebuild
Escalate
New profiles fail repeatedly
If clean profile creation, Office repair, credential cleanup, and connectivity checks all fail, preserve the evidence and escalate rather than stacking more changes.
Escalate
Repair tools also fail
When Office repair, uninstall, or Microsoft support tools cannot run normally, the workstation's Office installation or Windows state may be part of the issue.
Verify
Test the final profile and the real workflow
After recovery, confirm Outlook opens, connects to the intended address, synchronizes mail, and can send and receive.
If Outlook cannot build a clean profile, stop calling it a profile rebuild ticket.
