Re: Property tags - what happens if... (Rename of user defined fie

I had big trouble in making bulk Property change using Redemption, CDO and
Outlook object model.

Firstly, CDO is quick and straightforwaard enough to create the bulk rename
script quickly, BUT, does not support Unicode so it forgets every foreigh
characters during the conversion.

Secondly, the Outlook object model is terribly slow (does not matter, I
could let him do it overnight) but, worse is, as it is working on items with
customized form, memory grows, grows, grows, after several hundred of items
it all crashes, wow!

Interesting point, if I remove form prom folder, there is no memory leak,
but the script stops working :-) because UserProperties is dependant on the
form published in the folder.


Third: Redemption, it is Unicode, wow, it is quick, wow, it does not leak
memory, wow, but it does NOT work. >:-)

well as I declared
Dim up as Redemption.UserProperty
Set up=oMessage.UserProperties.Find(..., true) 'tried string, PropTag

I get Count 0, empty collection in debugger.

Strange behaviour however is, that when I first make
Set up_existing=oMessage.UserProperties.Add("myexistingpropertyname")

then o la la I can see instead of adding the value of my EXISTING value.

This way I finally made the bulk migration tool working somehow but withou
proper examples on the internet it was two days of really hard work - why the
objects are so non-intuitive ?
