we use EXCHANGE 2013 and we have many user which uses O365.
At the secretary office we have 3 users with same OS and same O365 settings.
The problem is the sync of these mailboxes and calendar entries.
When the boss creates a new calendar entry, the secretary cannot see the entry....sometimes it is synced but after several minutes.
How to fix this issue ?
What is the way to add a mailbox to another account ?
A new account ?
Or a new mailbox in the users account ?
Or just add the mailbox via full access rights on the mailbox ???
