Hybrid Migration Limits
What is the limit on UserMailbox Size that can be migrated from Exchange 2010 to O365? What is the limit on Archive Mailbox Size that can be migrated from Exchange 2010 to O365?

Hi Chandan,
The limits is 100Gb per Mailbox if you are using E3 or E5 and item is 150Mb.
You can view all limits here https://technet.microsoft.com/en-us/library/exchange-online-limits.aspx

You can enable auto expanding archives if the limit reaches 100GB, depending on your license. But for migration, each 100GB limit for User and archive.

Apart from any tool do we have any way to migrate archive mailboxes(that hosted in any archive solution like dell ) from exchange on premise to office 365 ?
