shared inbox - space limitation

Question

shared inbox - space limitation

IBN 4,511

Hello

We have a shared inbox for users. We normally get emails notifications about it in the inbox.

It seems we only have 5 GB space whereas it should be 50 GB.

Does anyone know how we can increase this limitation, I do not find resources online on how to fix it.

How do you know the mailbox has only a 5GB quota?

Hi @IBN

Are you using Exchange online? The Mailbox storage limits are introduced here

To access a shared mailbox, a user must have an Exchange Online license, but the shared mailbox doesn't require a separate license. Without a license, shared mailboxes are limited to 50 GB. To increase the size limit to 100 GB, the shared mailbox must be assigned an Exchange Online Plan 2 license.

Shared and resource mailboxes don't require a license. However, without a license, these mailboxes are limited to 50 GB. To increase the mailbox size, an E3 or E5 license must be assigned. This will increase the mailbox to 100 GB.

Or do you mean mailbox quota configuration for your shared mailbox? Please run the command below to check the value:

Get-Mailbox <User ID> | Select *quota*

You could set the quota using this:

Get-Mailbox | Set-Mailbox -ProhibitSendQuota <Value> -ProhibitSendReceiveQuota <Value> -IssueWarningQuota <Value>

Details: Increase or customize Exchange Online mailbox size
