Unable to Attach to Exchange Email

jcallantine

Sorry to bother you all with this but I am having quite the issue getting OsTicket to attach my my Exchange Server. I am able to get OsTicket to send email through smtp but I'm unable to get the system to attach and retrieve email (ticket responses or ticket request though email). I have the following information on my system:

When I go into emails / select default email / Remote Mailbox
I have my system host name and setting port number to 993, protocol to IMAP, Authentication set to Basic Authentication (Legacy) I put in my Username and Password ( I've verified the username and password through OWA) I recieve:

cannot connect to host ; error = fsockopen(): Unable to connect to ssl://mail.sbtribes.com:993 (Unknown error) (errno = 0 )

when I change the port number to 143 I get:

cannot login, user or password wrong

I have tried different entries for username. domain\username, username@domain, username. nothing seems to work and I wonder if I'm missing something elsewhere. Not quite sure what to try next.

Thank you so much for any response.

O365 no longer allows basic authentication (since October 2022). You will need to install the OAuth2 plugin from our website and follow the step-by-step guide to configure Modern Authentication (OAuth2) for O365 emails:

Are you talking about Exchange Online (EXO) or a local on prem Exchange?

If EXO, then Kevin is correct.

If on Prem does the user have permissions to connect to exchange via IMAP?
Do you have port 993 enabled?
Do you have a firewall between them that might be blocking the traffic?
When I used to have an on prem Exchange we logged in with just "username" but we had to give the account IMAP access, Exchange didn't have have IMAP enabled or access to IMAP enabled on the account by default. (this was circa Exchange 2013 or 2016)

we do have an on Prem Exchange server and we do have IMAP enabled for all users. I have made sure that the Firewall at the server does have TCP 993 open with no change in the status. again with the 993 I still get the fsocket error, but with 143 I get the bad password username. Ive also added TCP 143 and 993 to the outbound

Thank you,

Hmm.

How about windows firewall on the Exchange server?

You enabled imap on the account level... did you enable it on the server level?

I do have the IMAP and IMAP backend services running on the server. I have checked the Firewall and it is open for those ports.

Thank you,

Check the event log on the server and the client. I would check the Security log, and filter for errors and warnings to see if/why authentication failed.
Exchange also has log files in a subfolder in the installation path. Search for connect*.log, or just *.log.
