Hi,
We have two users mailbox which were migrated from Exch2003 to Exch2010 & then back to Exch2003. Now these users are receiving email but unable to send emails. While trying to send, getting mailbox full message whereas their mailbox size in ESM is not touching to restricted size. From both outlook & OWA, they are not able to send emails. I have tried to set send limit manually / create new profile but same status. Match mailbox rights / security permissions from working mailbox, but not seeing any difference. We have some other users also who have migrated on same path & working fine. But unable to understand why only these two users facing this issue only in sending emails.
Appreciate any help to resolve this issue.
