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
For E3 and above plans you can migrate user mailbox upto 100GB and archive it unlimited. For plans below https://www.o365cloudexperts.com/office-365-e3/ it will be 50GB for User mailbox as well as archive>
Here is the Office365 Limitation link for more details:
