Hi @Balamurugan - Admin

Thank you so much for contacting Microsoft Q&A Forum.

Based on your post, I understand you are looking for a way to increase a user's mailbox size using the Exchange Admin Portal.

Before we get to the specific steps, I found some information you might need. The maximum size for a user's mailbox depends on the license you provide to them. Here are the common limits:

• Exchange Online Plan 1 (e.g., in Microsoft 365 Business Standard): This provides 50 GB of primary mailbox storage and 50 GB for the archive mailbox.
• Exchange Online Plan 2 (e.g., in Microsoft 365 E3/E5): This provides 100 GB of primary mailbox storage and 100 GB for the archive mailbox (which can also be enabled for auto-expanding archiving).

With that in mind, I found two official documents that explain how to manage and increase mailbox storage. Please take a look at these:

1. Configure storage quotas for a mailbox in Exchange Server
2. Increase or customize Exchange Online mailbox size

Please let me know if I misunderstood your request or if you need any more information. I'll be waiting for your reply.
