Update mailbox quota
Here are the instructions - https://support.microsoft.com/en-us/help/2490230/how-to-set-exchange-online-mailbox-sizes-and-limits-in-the-office-365.
This is the command I tested and worked ok -
Set-Mailbox <account> - ProhibitSendQuota 99GB -ProhibitSendReceiveQuota 100GB -IssueWarningQuota 98GB
After running this command on test mailbox with a smaller quota, it was shown as having a 99GB mailbox available.

Thank you Cian !
I found that doc and issued the cmdlet and it worked !
Now I wonder why is this userid did not get the same quotas as the others... I'm the only admin of our tenant and I never played with quotas... strange ?
Good question! I don't know how old that mailbox is but 50GB was the original quota until the end of 2016 when it got increased to 100GB. If it was around then, maybe it just never got the auto upgraded value for some reason but just guessing really.
- Yes Cian, our mailboxes where created in 2011 ! All has been updated excepted this one... really weird !
Anyway, thanks for your support !The reason why you have some mailboxes shown at 49.5 GB is that they were created before Microsoft began to roll out the 100 GB quotas around December 2016 (see https://www.petri.com/exchange-online-mailbox-quotas-swelling). If users haven't complained, then they don't really need the space!
