How to increase a mailbox size ?

Currently we have 50 GB of mailbox size available, and one of the mailbox has reached this limit! I have to urgently increase the size but can't find the way to do it. Is it even possible??

With E3 and E5 in theory you should get unlimited archiving, wich is the MS solution to your problem. Unfortunately though I think the ulimited archiving rollout has been paused.

Maybe TonyRedmond can tell us what is the present situation.

Expandable archives were paused https://www.petri.com/exchange-online-expandable-archives-paused but my understanding is that the deployment is now complete or almost complete across all Office 365 datacenter regions.

The original question is what to do when a mailbox gets to 100 GB. Well, primary mailboxes do not have auto-expand capability, so when you get to 100 GB, your mailbox stops being able to accept new mail. That's the reason why running retention policies to remove or archive old content is a good idea. So the right answer is to archive-enable the large mailbox and apply a retention policy to remove old content and let MFA move the information for you.
