I have freshly deployed everything for my lab environment and everything went smooth. After creating users and while creating mailboxes for the users i am getting below error but the mailbox is created after the error.
"error Your request couldn't be completed. Please try again in a few minutes"
My environment :
2 - Root Domains - Replication Enabled, Prepared Schema, AD, Domain, AllDomains.
1 - Child Domain - Replication Enabled, Prepared Domain.
1 - Exchange MB/CA - Using SSL from CA and works fine (All perquisites were applied perfectly).
I am completely unable to understand whats goings on ?
Kindly suggest.
