On one of our computers, when we open Outlook it takes for ages to

How large is the PST and what version of Outlook?

Unfortunately he insists on having access to all of his emails once
in a while even those two, three or more years old
And as he is the managing director I have to accept it

Has anybody got an idea?

Divide the PST into multiple PSTs. Organize items in those PSTs in anty way
the director is comfortable. For example, move all messages received in
2004 to a PST named "2004" and move all mesasges received in 2005 to a PST
named "2005". If that ordering doesn't work, use another. Create a PST for
each sender, for example, and move all messages from the same person to a
PST dedicated to messages from that person. You can organize things in
whatever way the director wants to work.
