IM issue after upgrade from zimbra 5.x to 7.1.x

[Moox]

Hello everyone,
I'm getting a particular issue on the jive IM since my company migrated from a zimbra 5.x to 7.1.x release.
Let me explain :
on 5.x :

two users, A and B, used to "chat" through the IM service.

A blocked B's messages and B blocked A's messages.

then, B "unblocked" A, but A kept blocking B's messages.
a few days later, we migrated to 7.1.x:

A wants to unblock B. This feature doesnt appear on the "new" jive IM.
It seems all is managed through mysql database called "zimbra"
How could I make B talk to A again ?

A can talk to B ,but cannot receive B's messages.
Thanks for your support

Sadly, it's not possible :(
It leads me to the next question :

Is there any mean to "reset" a IM account (ie delete all IM contacts / buddies, and sign up to the service as if it was a account creation) - not the mailbox, only jive / IM service.
About the migration to another IM server:

I'm aware of the next removal of the IM server, and it's a service used by the whole company (300+ people). We can't deploy (actually, we are not allowed) another IM service.
Bonus question :

Except on the mysql database "zimbra", where can I find configuration about accounts ?

There's a bug (in your case, more like a bonus feature) regarding IM and mailboxmove- if you move a mailbox between mailstores, the buddy list gets lost. You might be able to move these accounts using zmmailboxmove and just tell them to start over with fresh buddy lists.

I'll try this out, thanks for the tips ;)
I told the user who doesn't receive the messages to install an XMPP client (pidgin), and guess what ... it's working "out of zimbra".
It seems to be more a problem of zimbra-webmail-interface than jive IM.
I keep searching :)
