hello,
i recommend you open a support case. you have various issues which need to be diagnosed separately.
1. smtp
if using office365 follow the following:
From Mailhost:
https://support.office.com/en-us/article/How-to-set-up-a-multifunction-device-or-application-to-send-email-using-Office-365-69f58e99-c550-4274-ad18-c8...
Requirements for SMTP client submission
Authentication: You must be able to configure a user name and password to send email on the device.
Mailbox: You must have a licensed Office 365 mailbox to send email from.
Transport Layer Security (TLS): Your device must be able to use TLS version 1.0 and above.
Port: Port 587 (recommended) or port 25 is required and must be unblocked on your network. Some network firewalls or ISPs block ports—especially port 25.
Configure in NetApp:
ONTAP 9 Documentation Center
system node autosupport modify
[-mail-hosts <text>, ...] - SMTP Mail Hosts
Use this parameter to specify up to five SMTP mail hosts through which the node sends AutoSupport messages. This parameter is required if you specify e-mail addresses in the -to, -noteto, or -partner-address parameters or if you specify smtp in the -transport parameter. Separate multiple mail hosts with commas with no spaces in between. The AutoSupport delivery engine attempts to use these hosts for delivery in the order that you specify.
You can optionally specify a port value for each mail server. A port value can be specified on none, all, or some of the mail hosts. The port specification for a mail host consists of a colon (":") and a decimal value between 1 and 65335, and follows the mailhost name (for example, mymailhost.example.com:5678 ). The default port value is 25.
Also, you can optionally prepend a user name and password combination for authentication to each mail server. The format of the username and password pair is user1:pw1@mymailhost.example.com. The username and password can be specified on none, all, or some of the mail hosts.
Note that if you mailhost requires the email address for the login then you need to modify the setting and change the (@ symbol for %40) per this bug-

Sooo , for the mailhost they would configure it like so:
username%40companydomain.com:Test123!@smtp.office365.com:587
2. myautosupport portal
this requires about 24 hours after setting up Autosupport. if the issue still persists we need to look at the:
- Cluster and check if the performance counters are being collected.
or
-look at myautosupport portal for possible issues.
