Exchange to Office365

Hi,

I’m have just started an exchange to Office365 migration, I have just migrated my first test batch and have found that the mailbox has been created in O365 (I have added the licence), in exchange the user is listed as a contact but some test emails go to the old mailbox and are not showing when I logon to office.com and some emails do show online,
The OWA link within outlook is still pointing to the on-prem server not Office365.
I have deleted and recreated the mail profile for outlook and the same happens, can you suggestions I try anything?

Regards,

You can export Exchange mailboxes to Office 365 directly by the automated tool named Kernel for Exchange Server recovery software. It is an automated tool using which you can perform multiple operations like Exchange to Office 365 or, Live Exchange, Outlook PST migration.

You need to be more specific here. First of all, which migration method are you using? And what do you mean by "old mailbox", if the user "is listed as a contact"?
Agree with Vasil. Please make us more clear to give you a better answer.
-->go to the old mailbox and are not showing when I logon to office.com and some emails do show online,
U mean your old email which is received before moving doesnt exists in your mailbox after moving to O365?

Hi,
Its a staged migration
the mailbox called test on the old on-prem exchange is listed as mailbox type - Office 365

So what is the "old mailbox" you are referring to then? Did you or did you not convert the mailbox to mail user after the migration? As in this step of the process: https://support.office.com/en-us/article/Perform-a-staged-migration-of-email-to-Office-365-83bc0b69-de47-4cc4-a57d-47e478e4894e?ui=en-US&rs=en-US&ad=US#bkmk_step8
