Can I use MailMerge365 with the GoDaddy version of Microsoft 365 (Office365)?

Unfortunately the Microsoft 365 (aka Office365) offerings from GoDaddy are not 100% compatible with the real offering from Microsoft. There are several differences and incompatabilities.

Due to these incompatibilities MailMerge365 currently cannot support Microsoft 365 accounts that were purchased through GoDaddy.
