We run Exchange 2010. In our organization, we have a team of users that all connect to the same mailbox in Outlook. Recently an issue came up where a user would come in later in the day and not be able to connect to Exchange in Outlook.
Later, after a few people go home, said user can connect. Is there a limit as to how many users can connect to the same mailbox at one time? If so, can this limit be increased?
