Removing the filter within Outlook98

Does "it is deleted afterwards" mean it is moved to the "Deleted Items" folder, removed from the server but kept in his inbox, or lost completely?

View > Current View > Define Views.  You can highlight each view (filter) and click reset to get back the default view.

All emails are lost completely.

This does not sound like a "Filter" setting but a problem with Outlook or Exchange.  When the user gets new mail, does it go to his Exchange mailbox or his Personal Folders?  If he moves a mail before reading it, is it still lost when read?  When does it actually become lost (As soon as the message is closed, when closing Outlook, ?)

Bert

All emails go to the Exchange mailbox.
However after reading and then closing the email it is lost without any trace of it in any folders.

Check with your Exchange Administrator.  It appears that the server is set to delete read messages immediately.  To work around, select all messages in the inbox, right-click and select "Move to folder" and move them to another folder.  Build a new folder for this purpose if necessary.  Or you can install Personal Folders (if they are not already present), then change "Delivey Options" to the Personal Folders Inbox instead of the Mailbox Inbox.

Sorry, I should have mentioned where to change the delivery options.  Go To Tools, Services, Delivery and choose "Personal Folders" from the "Deliver to. . ." dropdown list.  If you use the "Move to Folder" option, be sure to do this BEFORE the messages are read.
