Is there an Office 365 Post migration checklist or test plan for end users?

Hi Faiza,

Normaly the check list is before migration of real users, for example:

• Mail flow
• Access from Office 365 Portal
• Access with devices
• Shared Calendars
• Open additonal mailboxes
• OWA Redirection
• Autodiscover in Outlook
• Experience and Outlook migration tests

After all this check lists, have passed and more that could be relevant to your migration scenario, you are all set to do the migration and to the end users just send a feedback form about the new experience, not test to do.
