Hi everyone ,

i migrated this week to exchange 2013 in coexistence with exchange 2007 ,,,, is it normal that i cannot create anymore a mailbox on the exchange 2007 server even with the console (ecp) in 2013 ?? 

thanks

You can't create a mailbox through the EAC (2013) and point it to a 2007 Database.  You should be able to create a mailbox on the 2007 EMC and point it to the 2007 environment.  Have you tired that?

I did the exact same migration not long ago and I can create users from either management console to both 2007 and 2013 Databases.

Is that the only issue you are coming across?  You have no problem sending/receiving from users on the 2007 server?

From the console in 2007 , i got

error the exchange server address list service failed to respond

thanks all

Are there any errors in the event viewer on the 2007 side?

OK i restarted the system attendant and it fix this issue

thanks
