4. Resource Mailboxes
5. Distribution Lists
6. Global Address List (GAL)
For each account you needed to supply:
NB: You are not able to access a project account via Outlook until it is in the address list.
Accounts can be unhidden on request
7. Project Accounts
Note: A "user" of a project account is not authorised to request SendAs rights unless they own the project account.
8. Junk Email/SPAM Filtering
[Automatically filter junk e-mail]" setting in the
Junk E-mail screen is enabled.
The Junk mail filters on Nexus cannot be set to automatically discard email that passes a certain threshold (as Herald did). To compensate for this, the Nexus Junk E-mail folder automatically deletes emails from the Junk E-mail folder (and ‘deleted items’) after 90 days. Some users are annoyed that some persistent spam, or irksome personal messages still arrive in their Junk E-mail folder. These people can be helped by either creating a rule on the Junk E-mail folder to delete certain emails immediately, or in the judicious use of Blocked Senders. See: http://www.oucs.ox.ac.uk/nexus/web/light_guide.xml?ID=filtering
The spam-filtering process is explained in detail here: http://www.oucs.ox.ac.uk/nexus/itss/message-flow.xml
9. What happens to a user's mailbox when their University Card expires?
When someone's University Card expires and they leave Oxford (and this notably includes "student leavers") their mailbox is usually deleted after 3 months. Departing users can usually extend this period if they ask for an extension at the OUCS help centre.
Users can set up forwarding that works for 2 months following departure/card expiry.
N.B. 00F = Out of facility message = Out of Office = Vacation Autoreply
Consider 3 categories of departing users: (A) Users who have forwarding set; (B) users who have a vacation message set (OOF); (C) users who have neither OOF nor forwarding set.
On card expiry, all 3 groups of users cease to have access to their mailboxes. For users in groups A and B, nothing else happens until the end of month 2. Users in group C have an OOF created saying that, "This account is scheduled for deletion. It is unlikely that your message will be read." (Also, if a mailbox belonging to group B has its OOF expire or switch off before the end of two months, that change should be detected within hours and the standard message applied.) At the end of month 2, mailboxes are 'detached' (or 'disabled'), and the routing tables are changed so that mail will not enter Nexus from outside. After a further one month, the mailboxes are deleted, but remain on tape for about 60 further days. (Tape retention policy is subject to change, however, and should be detailed in the Exchange SLD).
