Hi,

 

We migrated our e-mail server to Office365. We also use ManageEngine Service Desk Plus in our environment. We have multiple accounts configured in our SDP, each having different support e-mail address. So, when we reply to any request from the tool, it will go as the support e-mail address mentioned for each Account. Also, we have the users sending e-mails to the support e-mail address. The e-mails addressed to the support e-mail address is forwarded to our primary e-mail account, which is mentioned in Service Desk Plus.

 

Issue.

 

After migrating to Office365, we are not able to send reply to any requests. But, if the support e-mail address is removed for any account, the e-mails will be sent. At this time, the recipient will get the e-mails from our master e-mail account, which is specified in Mail Server Settings page, and not from the support e-mail address. If we put in the support e-mail address, we get a plain error page mentioning "Sending notification failed"

 

Any Idea why this is so?
