I need to view mailbox size quotes and add warnings.

Is there no way to do this via the O365 Admin Portal > Exchange Admin Portal at all?

I would like to find out what the default quotas are and if I can edit them for specific mailboxes.

    The mailbox type and the user's subscription license determine the amount of mailbox storage available. Administrators can reduce maximum mailbox sizes per user or globally.

    https://learn.microsoft.com/en-us/office365/servicedescriptions/exchange-online-service-description/exchange-online-limits#mailbox-storage-limits

    To view Quota of mailbox, you can connect to Exchange Online PowerShell and run the below cmdlet

    Get-Mailbox JDoe@contoso.com | Select *quota*
    

    To Set Quota of mailbox, you can connect to Exchange Online PowerShell and run the below cmdlet

    Set-Mailbox JDoe@contoso.com -ProhibitSendQuota 19GB -ProhibitSendReceiveQuota 20GB -IssueWarningQuota 18GB
