Hello.
Did anyone here has idea, how to restore missing folders? They even are not visible in Designer 
Only restore can do this? And what next?

You need to recover those mail files from backup. If the folders are gone from the design, they are gone.
The most common reason for this to happen is, that folders did not have the “Prohibit design refresh or replace to modify” checkbox set. If a user creates a folder in Notes 6, 7 or 8, the box will automatically be marked (resulting in “P” being included in $Flags. However, in earlier releases (at least up to 4.6 and I believe in R5 as well), this boc was ticked only, if the mail file was set to inherit design from a template.
Why organizations choose to not inherit the design of their mail databases from a template is beyond me, but whether or not this was the cause in your case, the way to prevent the folders from being erased is the same: Write an agent that loops through all views in all mail databases, check if the view is a private folder and if so, add “P” to $Flags.
You should be able to find ready baked code either in this forum, or doing an internet search on some of the keywords mentioned.

Thank you.
But what to do, when folders are protected and design upgrade will remove them anyway…? It happened only one time, so far so good.
So, I’ll have to organize restore… once again thanks.

“But what to do, when folders are protected and design upgrade will remove them anyway…?”
Restore from backup ( 
), see, if the problem can be reproduced and contact IBM support. I’m afraid, that’s all you can do, because this should definitely not happen.

Anyway, thanks.
