Thanks for the reply. I've verified the API permissions and Authenticated SMTP. No policies in effect that would restrict/block SMTP.

      Yes, I am. The enterprise app and app registration is shared among all of the email accounts within osticket, but I am using an incognito window and authenticating with each unique user/mailbox login. Also, if it matters, I’m using the tenant-created accounts with onmicrosoft.com logins/addresses. It’s been setup that way since changing over to OAuth.

          Then you should be fine. Maybe disable SMTP, reenable it, and retest for each account?

          Cheers.

              We also have this problem with SMTP.

              The "hack" worked OK for the accounts we use to only receive email, but the account we use to send cannot authenticate:

              This is not a new account, used to work fine up until yesterday.

                Thanks for confirming. I have disabled and enabled Authenticated SMTP for these accounts and will be testing in a few hours.

                  I created a ticket with Office 365 support and they recommended a test via powershell:

                    Let's first turn off MFA, Conditional Access Policies, Security Default.
 
  Then you could run PowerShell commands below to narrow down done if the issue occurs within our side. If the PowerShell command can send successfully, then the issue occurs within just the app scope but not from our side.
 
  $cred = get-credential
  Send-MailMessage -To "user@domain.com" -from "user@domain.com" -Subject 'Test message' -smtpserver smtp.office365.com -usessl -Credential $cred -Port 587

                  The results of that test email were successful and I received it from one of the accounts that is used by OSTicket.

                      Then I am unsure. It’s working for everyone else so it’s a config issue somewhere in your end.

                      Cheers.

                          KevinTheJedi As I said it's not working for us either, so it's definitely not working for "everyone else". Has anyone else confirmed specifically that SMTP works for them?

                              The only thing I can recommend at this point is to maybe create a brand new App Registration in Entra and following the osTicket OAuth2 documentation exactly as it states. Also, you should now be using the Scopes of offline_access https://outlook.office.com/IMAP.AccessAsUser.All https://outlook.office.com/POP.AccessAsUser.All https://outlook.office.com/SMTP.Send.

                              As long as you modify the plugin as stated above, use the correct Scopes, and authenticate as the correct user you should have no issues. I just retested with my O365 personal email and it's working as intended for both IMAP and SMTP using these instructions.

                              Cheers.

                                  @symoss how long do you use this account?
                                  Maybe your certificate is outdated. You can check your client secret. It will expire all two years.

                                    i got the plugin edited, i cant seem to figure out how to manipulate our database. i was able to login to mariadb, i got to the database, and tablet contents, but im strugging to put together the right update command to change the install path and the 1 to 0. can you provide any help on this? also, im using Government 365 if that matters.

                                        bbertling

                                        Ahhh then you have completely different endpoints and everything. All endpoints for O365 government end in .us instead of .com. Furthermore SMTP is typically disabled for Government tenants and you typically use a relay for that.

                                        As for the SQL, you should use a GUI tool instead if you don’t know how to run/write SQL statements as you can mess up quite a bit. I would recommend HeidiSQL for windows and Sequel Ace for Mac.

                                        If you require a manual query you would just simply run:

                                        UPDATE %TABLE_PREFIX%plugin SET `install_path` = 'plugins/auth-oauth2', `isphar` = 0 WHERE `id` = %PLUGIN_ID%;

                                        Replace %TABLE_PREFIX% and %PLUGIN_ID% with their respective values.

                                        Cheers.
