Hi,@Muhammad Sohaib
Thanks for posting your question in the Microsoft Q&A forum.
Assigning Exchange Online (Plan 1) and SharePoint Online (Plan 1) licenses to users who already have Microsoft 365 F3 licenses will have the following impacts:
- Exchange Online Mailbox Quota: The mailbox storage quota for users will increase from 2 GB (as provided by the M365 F3 license) to 50 GB, which is the quota provided by Exchange Online (Plan 1). Users should be able to continue using their mailboxes without interruption during this upgrade.
- OneDrive Storage: Again, OneDrive storage space may increase depending on the specific plan. If a user is also assigned OneDrive Plan 1 as part of their license, they will receive 1 TB of storage.
