The Outlook title bar shows the primary email address that your current profile is using in the middle, for example Inbox - your.name@unit.ox.ac.uk - Outlook. If you have moved department and this has not updated then you can follow the guidance on this page to remove your old profile and set up a new one.
Outlook will automatically prompt you to set up a new profile if one doesn't exist when it starts. Follow this guide if you want to manually create a new profile for any reason. You might wish to do this if you have two email accounts that need to be kept strictly separate.
Select Start , start typing control, and select Control Panel. Select the Mail (32-bit) icon
Select Show profiles > Add
Enter a name for the profile and select OK. "Default" or "Outlook" are good choices of name if this is the only profile
The process to add a profile for a secondary account is almost the same as for other accounts.
Follow the process to add a new profile, incorporating the following changes:
When configuring your email, provide the secondary account details (you do not initially need to provide a password).
If the mailbox is being set up for an account delegate, when later presented with a Windows security or sign in box, the displayed email address must be replaced with the delegate's own username details (for example abcd1234@OX.AC.UK), then their own Single Sign-On password.
If you have multiple profiles then Outlook will either start with a default profile, or prompt you to select one each time. Follow this guide to select or change the default profile.
Select Start , start typing control, and select Control Panel. Select the Mail (32-bit) icon
Select Show profiles
Select Always use this profile and choose the profile you want Outlook to start with from the dropdown list. Alternatively, select Prompt for a profile to be used if you would like to choose your profile each time Outlook starts
