I have a question about Enterprise CALs and Archiving.
As I understand it, to add an archive mailbox to a user, they need an Enterprise CAL to access the archive mailbox via Outlook. However, I noticed that they are able to access the archive mailbox via OWA.
I am in the process of upgrading my customers from Office 2007/2010 Standard to Office 365 Business, however, this will be a slow process due to Office Documents that aren't compatible with Office 365, I am also wanting to implement Mailbox Archiving.
My question is, from a licensing point of view, is it okay to create an archive mailbox for a user on the understanding that they will only be able to access it via OWA (until they are upgraded to Office 365)?
I believe that Office 365 Business includes an Exchange Enterprise CAL, so I don't want to have to pay for two CALs for the one user.
