Bad sequence of commands SMTP setting using OAuth2 for O365

Davidleecs

I'm getting error when setting up the SMTP with OAuth2 authentication same as remote mailbox for O365 and getting error Bad sequence of commands below.

Osticket ver 1.18.2
Apache 2.4.58
MySQL 8.0.41
PHP 8.1.32
OAuth2 client plugin ver 0.6

There is no issue saving for incoming mailbox and I can see the OAuth2 Authorization token scopes below
https://outlook.office.com/IMAP.AccessAsUser.All
https://outlook.office.com/Mail.ReadWrite
https://outlook.office.com/POP.AccessAsUser.All
https://outlook.office.com/SMTP.Send
https://outlook.office.com/User.Read

Is there anyone encounter same issue and appreciate can share workaround resolution?

Please read the system requirements before upgrading/installing. You have PHP 8.1 but the minimum supported now is 8.2. Please upgrade and retest.
You’ll can’t use Mail.ReadWrite anymore so remove that scope and reauthorize the email.
Ensure Authenticated SMTP is enabled for the email in Office365. Make sure you have no policy attached that would prevent it, etc.

Cheers.

Thanks for sharing these info. I've follow your advices, updated the to latest PHP 8.4, remove Mail.ReadWrite scope and reauthorize the email but still getting same error Bad sequence of commands.

Then the only thing I can think of is your hosting provider is blocking/restricting external SMTP.
