How to switch from individual to family subscription MS365 & Outlook/Hotmail

Michelle Shuck 0

I have an individual MS365 plan including a hotmail/outlook email account I've been using for 30 years. I recently purchased a Family subscription after purchasing a new laptop for my husband to download MS Office on his computer, and need to merge my account into the Family plan, but I purchased it with his name. How can I add myself into the Family plan so that my Outlook email then has a larger storage capacity. I am well within storage on the email account, but it shows this notification in my email browser:

"Subscription expiring...you are over the free limit for storage. Turn on recurring billing to avoid losing the ability to send and receive messages."

Hi, @Michelle Shuck

You don't need to merge your accounts or change your existing Hotmail/Outlook email address. You simply need to join your husband's Microsoft 365 Family subscription.

Ask your husband to:

Go to https://account.microsoft.com/services/office/sharing
Select "Share" and send an invitation to your existing Hotmail/Outlook email address.

Then, open the invitation using your existing Microsoft account and accept it.

Once you join, your existing account will receive the Microsoft 365 Family benefits. Your emails and files will remain under your current account.

You can also turn off recurring billing for your Personal subscription to avoid being charged again: https://account.microsoft.com/services

Thanks!

Thanks! I did this but am waiting for it to register as completed in his account. It still shows "Sharing 0 of 5" when I look under subscriptions in his account. Do you know generally how long it takes to have access to the shared plan after joining via the invite?

Thanks for the update!

Microsoft indicates that it can take up to 2 hours for the shared storage benefits to appear.

In the meantime, please check the following:

Make sure you selected both "Accept" and "Join now" using your existing Microsoft account.

Ask your husband to check the sharing page: https://account.microsoft.com/services/office/sharing

Confirm that your account is listed as a member and that the invitation is no longer pending.

If it still shows "Sharing 0 of 5" after 2 hours, let me know. We can check the invitation and sharing status further.

Thanks!

John, I have now completed the share/invite process so many times that the system says I have to wait 30 days to send additional share invites. I stepped through the process multiple times from my husband's account, then attempted to log into my hotmail account...that's where things go belly up. It still shows "0 of 5 shares". I was even able to make myself, as a family member in his account, the "organizer", but for some reason, the Outlook/Hotmail access is not happening (I assume) because the system is still registering "0 shares"...which conflicts with the fact that I'm showing as a family member within his account. Please help!

As an update, I read on Google the following, and am assuming this is the issue:

"You are tied to another license: If your account is still linked to an active Microsoft 365 Personal/Basic subscription or tied to a different family group/organization, the system will block the share from attaching properly."

My biggest concern is that the transition from my old subscription to the new family plan will not be smooth and/or timely, and I could potentially be without access to my email (which I use exclusively for all correspondence). Do you have any advice/experience with this process?

Answer 2

Your husband must share the Microsoft 365 Family subscription with your existing Hotmail/Outlook Microsoft account; accept that invitation using the same account so your mailbox remains intact and receives the shared subscription benefits.

Add your existing account to the Family subscription

Your husband signs in as the subscription owner at the Microsoft 365 Services & subscriptions sharing page: https://account.microsoft.com/services/office/sharing
Select Share or Start sharing.
Select Email invite.
Enter your existing Hotmail/Outlook email address—the address connected to your current Microsoft 365 Personal subscription—and select Invite.
Open the invitation while signed in with that same Hotmail/Outlook account.
Select Accept or Get started, followed by Join now. The invitation must be accepted within 48 hours. [^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Share your Microsoft 365 subscription | Microsoft Support")
After acceptance, check your Microsoft account’s Services & subscriptions page. It should show that Microsoft 365 is being shared with you.

Do not create another Microsoft account or try to move the Hotmail address into your husband’s account. Two existing Microsoft accounts cannot be merged, and an existing Outlook.com address cannot be attached to another existing Microsoft account. ^2^

Your email, contacts, OneDrive files, and other personal information remain under your account and are not exposed to the subscription owner or other family members. [^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft 365 subscription sharing FAQs")

About the expiration and storage warning

The warning appears because your current Personal subscription is approaching expiration and the account is being evaluated against the free storage allowance. When a subscription expires:

The account and mailbox remain in place.
OneDrive returns to the free storage quota.
Outlook.com can stop sending and receiving mail if either the cloud-storage quota or mailbox quota is exceeded. [^4^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "What happens when your Microsoft 365 subscription expires | Microsoft Support")

Once the paid Family benefit is active on your existing account, Outlook.com provides a 100 GB mailbox per person; the increased allowance may take a short time to appear. Outlook.com email storage and Microsoft cloud storage are separate quotas, although Outlook.com attachments also count toward cloud storage. ^5^

To identify which quota generated the warning, open Outlook.com and go to:

Settings → Account → Storage

Check both mailbox usage and Microsoft cloud/OneDrive usage. Being within the email mailbox limit does not necessarily mean the cloud-storage quota is also within its limit.

If the invitation cannot be accepted

“Already in another family group”: leave that other Microsoft family group first, then have your husband resend the invitation. A person can receive shared benefits only while in the subscription owner’s family group. [^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Share your Microsoft 365 subscription | Microsoft Support")
No Share/Start sharing button: verify that your husband signed in with the Microsoft account that actually owns the Family subscription. Someone receiving a shared subscription cannot share it again.
Invitation expired: your husband can find your pending entry on the sharing page and select Resend invite.
Storage warning remains after Family appears on your account: allow time for the paid allowance to update, then recheck Settings → Account → Storage. If the mailbox itself exceeds 100 GB, joining Family will not raise it further; storage must be reduced. ^5^

There is no need to change your Hotmail address, migrate your mailbox, or reinstall Office merely to move from one Microsoft 365 home subscription to another.
