Office 365 archive and mailbox size

I have a gmail user with 70GB of email, wanting to migrate to office 365,
I know that office 365 offers mailboxes up to 50GB.

What options do I have. and what is the archive feature they have. how does it work?

Todd NelsonSystems EngineerCommented:
Mailbox sizes in EXO vary depending on the subscription you purchase.  If Enterprise E3 or E5, the mailbox size limit is 100 GB and the archive size is unlimited.  The others, with the exception of Enterprise F1 which requires an archive license, are 50 GB and 50 GB respectively.

However, the archive seems to be flexible (with auto-expand enabled or with a call to support).

Review this guide ...

Archiving will be dependent on you configuring retention tags and policies...

For migrating mail data, I would highly recommend BitTitan for that task.

Well what plan you have taken in 0365. It depends on subscription you have taken for 0365 .
Sandeep KumarAssociate ConsultantCommented:
First thing is subscription of Office 365 what you have like Gaurav said.
Then you can proceed to with two steps:
1) Backup Gmail account data in PST format
2) Export PST to Office 365 either manually or by using PST to Office 365 tool.
