Hello All,
I'm getting error ID 1026 in exchange 2013 CU7 OS2012 since the last 7 days :
User "domain\HealthMailbox91a24f9" cannot access their mailbox on Mailbox server "server name" because the user's mailbox quota has been exceeded.
I found that user in AD, but there is no mailbox associate with it. I believe this account related to exchange server. I couldn't find any related article or troubleshooting for it. How can i solve this error.
Best Regards,
