Is there documentation accessing in-place archive mailboxes? we believe it is supported but our developer is struggling.!
Agreed with the post and subsequent comment. The inability to access Archived Mailboxes is a huge problem. The majority of a user's email many times resides in the Archive Mailbox, The inability to access those emails forced us to use the EWS API which we hear is on the road to deprecation. Graph needs to support functionality that has been in the EWS API for years.
