Mail in InSIS
- 50MB mailbox capacity – after exceeding the capacity, most emails are rejected
- ~18MB maximum size of one message including attachments (i.e. one message can take over one third of the mailbox capacity).
Mailbox Appearance, Mail Redirection
The following illustration shows the appearance of a mailbox in InSIS if the distribution server is set to Office 365:
Operation is simple and easy to understand. I will highlight only some details:
- The set redirection is highlighted at the top of the mailbox. The illustration shows an automatic redirection that is created after the mailbox is moved to Office 365.
- Even if you have a mailbox in Office 365, you can still read your Inbox or send new email messages in InSIS.
Automatic Cancelation of Mail Forwarding in InSIS
InSIS has built-in protection against non-functional forwarding – if the destination external server starts to reject emails (full mailbox, wrong address, …), InSIS cancels the forwarding set and displays a warning to the user when logging in to InSIS. The motive is to reduce the loss of emails.
