I'm in the process of setting up our Freshservice instance but have run into an issue with email going from Freshservice to our end users. When an email from Freshservice is received in Outlook it has two errors under the address details:
"We could not verify the identity of the sender"
"The actual sender of this message is different than the normal sender"
I've setup the SPF record correctly and can see from the message header that the SPF check has passed.
I've also setup a rule in exchange online which sets the emails to bypass the spam filter with a report being sent to myself every time the rule is triggered so I can see this is also working as it should, I can also see in the message header that the SCL is set to -1.
I've also tried adding the address to our safe sender list but this made no difference either.
Any help would be greatly appreciated.
