Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Greetings!
This is Tin, I'll do my best to help. The Linkedin Premium Career subscription is part of the student bundle, but it needs a separate redemption step. Sometimes the redemption link can take days to be sent, please make sure to check your inbox and junk folder from time to time. Kindly also visit https://account.microsoft.com/services, sign in your MS Account and check if you will see an option to redeem your Linkedin. If not, please reach the MS Support.
Kindly open this link: https://support.microsoft.com/contactus/
Please sign in your account with the subscription, then click Microsoft 365 then choose Get Business Support. After that, please type Chat with an agent then hit enter. Scroll down and choose Contact Support, then please select MS 365 and Office then under Category, choose Billing and Account Profile question then hit next. You will see the chat option there.
Once you're connected to the Live Agent, please let them know about your issue so they could check your account and address your concern.
Thank you,
Christine L
