Hi Pavel. Thank you for your reply.
However I'm still with problems to access the archive online. Sorry me for my doubt, but the 'In Place Archive' is same as 'Shared Mailbox' which you said in your previous answer?
To improve the understanding of my problem I'm sending a little description of my scenario. I have two users (firstname.lastname@example.org and email@example.com). The user1 is configured to access all features of user2 mailbox. To connect in user2 mailbox I am using the following code:
Using this code the user1 can access all folders of user2 perfectly and perform all actions which I want but I can't access the 'In Place Archive' of user2. I tried to access the mailbox following the tips in previous answer but I can't have success. Do you know same way to access the mailbox?
Sorry if my doubt is stupid or obvious but I'm beginner in those technologies.
