I am having this issue where multiple PC's on the network are unable to get into outlook 2003 sometimes. they click it and it says 'the operation failed'
if I keep clicking it, eventually it goes in, works fine and all functions are fine.
I have re-installed office and this still makes no difference.
I have disabled add-ons with no luck either.
it wasn't happening a few days ago, now a fair few PC's are affected.
