I have a couple of users that cannot use the, "Add Sender to Address Book" feature. They get the error: "Cannot Open Personal Address Book".
We are using Notes 4.5.2 with a Domino 4.7c server and all the proper file names and permissions seem to be in place on location docs, .ini files, database access lists, etc.
I don't know of any reasons for this to happen, but I do suggest you move to R5 immediately. Support for all 4.5x is over on September 30th, 2001. If you have a problem after that, Lotus will not assist you. Also, no downloads or upgrades will be available.
