Hello,
I am having an issue where 2 of my users (out of 700) cannot connect outlook to out Exchange 2013 server (any version of outlook on any computer).
I will start with a little backstory, our SAN had some drives that went bad two weeks ago, luckily we did not lose any LUNs, but it seems to have corrupted the exchange database in the process.
I was having issues doing backups with AppAssure so the Exchange server was restarted, when it came up the exchange DB was in a dirty shutdown state.
I was then able to recover the database and get everyone but 3 users working. The MailBoxrepair would not fully run on any of the 3, and 2 of them were crashing the DB and were then getting quarantined for it. One of the users I fixed by creating a new DB and moving them over to it, so we're down to the 2 I am talking about now.
In fixing their mailboxes, I backed up their PST's, then disabled their mailboxes (not deleting them) then created a new mailbox for each, then re-imported their PST's.
This worked for each user, but existing users could no longer send mail to these 2 users as they were getting bouncebacks of undeliverable with the following
IMCEAEX-_o=NSUP_ou=First+20Administrative+20Group_cn=Recipients_cn=User@domain.com
Remote Server returned '550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found'
According to the info I found, this was due to the legacyExchangeDN attribute being incorrect, so I updated it to match the format of the users in the organization (had what appeared to be a GUID at the end of it previously), and others were then able to send mail to these 2 users.
At this point, Outlook for each of the users refuses to connect to the Exchange server and update their email. I can open Outlook with a previously created profile and see all of the old mail, but cannot send or receive new.
Trying to create a new Outlook profile and login results in "Cannot open your Default folders, you must connect to exchange once..." but the initial setup of the account autodiscovers and works properly.
Disabling cached exchange mode results in a different error, which is along the lines of "Cannot open your .ost file"
Both users currently are working via OWA with no issues, but obviously this is not the best solution.
Below is a snippet from the RPC logs

The value of the legacyExchangeDN is
X500:/o=ORG/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=User
I have tried with and without the X500 before, but errors are the same
Does anyone have any ideas as to why these two users only cannot connect?
