Microsoft OneDrive problem

To keep everything working with Microsoft 365 Personal, avoid data loss, and safely cancel Microsoft 365 Basic, the key is to:

1. Make sure all OneDrive and Outlook data is associated with the Microsoft account that owns Microsoft 365 Personal (the @ziggo.nl-based Microsoft account in this scenario).
2. Reduce or remove dependency on the @outlook.com-based Microsoft 365 Basic account so that canceling it does not affect needed storage or services.

From the provided information, only the following supported and relevant points apply:

1. Microsoft 365 Basic vs Personal
   • Microsoft 365 Basic provides 100 GB of OneDrive storage and web-only Office apps; it does not include the right to install desktop Office apps.
   • Microsoft 365 Personal (and Family) include the right to install the Office apps locally on the PC, plus 1 TB of OneDrive storage and other premium benefits.
   • Therefore, the Microsoft 365 Personal subscription is the one that should be used for desktop Office on the Windows 11 PC.
2. What happens when canceling Microsoft 365 Basic
   • When a Microsoft 365 Basic subscription is canceled, the storage allowance for that account reverts to 5 GB of cloud storage (shared by OneDrive and Outlook.com attachments) and 15 GB of Outlook.com mailbox storage.
   • If the data stored under that Basic subscription exceeds the free allowance after cancellation:
     • New files cannot be uploaded, edited, or synced to OneDrive for that account.
     • Email cannot be sent or received in Outlook.com for that account.
     • After 12 months, OneDrive and all files in it may be deleted for that account.
   Because of this, before canceling Microsoft 365 Basic on the @outlook.com account, OneDrive and Outlook.com data under that account must be reduced below the free quota or moved/exported elsewhere (for example, downloaded and stored under the Microsoft 365 Personal account’s OneDrive).
3. Storage scope and what counts against the quota
   • The Microsoft storage quota for a personal Microsoft account includes:
     • OneDrive files and photos (including items in the Recycle Bin).
     • Outlook.com attachments and inline images.
     • Microsoft Teams message attachments and recordings.
     • Loop meeting notes and Ideas files.
     • Images in Designer projects.
   • This applies separately per Microsoft account. Each account has its own storage dashboard and quota.
4. Checking and managing storage before canceling For each Microsoft account (the @ziggo.nl-based account with Microsoft 365 Personal and the @outlook.com-based account with Microsoft 365 Basic):
   • Sign in to the Microsoft account dashboard and check the Microsoft storage area to see:
     • Total quota (5 GB free, 100 GB Basic, or 1 TB Personal).
     • Current usage.
   • If the @outlook.com account is over 5 GB but under 100 GB, reduce its usage to 5 GB or less before canceling Basic by:
     • Deleting or downloading and moving OneDrive files elsewhere.
     • Emptying the OneDrive Recycle Bin.
     • Cleaning up large Outlook.com attachments and old mail.
   Once the @outlook.com account’s usage is at or below 5 GB, canceling Microsoft 365 Basic will not immediately block access or cause deletion, and the account will continue to function within the free limits.
5. Calendar and primary email address
   • A Microsoft account’s username is an email address, which can be an Outlook.com address or a third-party address (such as @ziggo.nl).
   • Calendar and Outlook.com features are naturally tied to the Outlook.com-based Microsoft account (for example, @outlook.com or @outlook.nl), which can remain the primary email for calendar use even if its subscription is Basic or free.
   • The Microsoft 365 Personal subscription can be purchased and associated with a different Microsoft account (the @ziggo.nl-based account), and that account is what controls the Office app licensing and 1 TB OneDrive storage.
6. Using Outlook and OneDrive with the correct account
   • On the Windows 11 PC, sign in to the Office apps (Word, Excel, Outlook) with the Microsoft account that owns Microsoft 365 Personal so that desktop apps are properly licensed.
   • Add the @outlook.com/@outlook.nl mailbox as an additional email account in Outlook (Classic or New) so that email and calendar continue to work from that address while the Office license comes from the Microsoft 365 Personal account.
   • For OneDrive on the PC, configure the OneDrive client to sign in with the Microsoft 365 Personal account’s OneDrive (the one with 1 TB). If needed, files from the @outlook.com account’s OneDrive can be downloaded and then uploaded into the Personal account’s OneDrive before canceling Basic.
7. After canceling Microsoft 365 Basic
   • The @outlook.com/@outlook.nl account will revert to 5 GB OneDrive + 15 GB Outlook.com storage.
   • If storage was reduced beforehand, email and calendar on that account will continue to work within the free limits.
   • The Microsoft 365 Personal subscription continues to provide:
     • Desktop Office app usage on the PC.
     • 1 TB OneDrive storage for that account.
     • Other subscription benefits.

This sequence ensures that:

• No OneDrive data is lost (data is moved or reduced before cancellation).
• Desktop Office remains fully licensed via Microsoft 365 Personal.
• The @outlook.com/@outlook.nl address remains usable as the primary email and calendar identity.
• The Microsoft 365 Basic subscription can be safely canceled once its account’s storage is within free limits.
