What happens if a guest user acess to a Group using his/her personal account vs professional one?
Yes, I have seen this many times...
The account (MSA or O365) used to accept the invite is the one that needs to be used in the future.
As bart_vermeersch said, if you want to change it, you have to send out a new invite.
BTW, it is not possible anymore to create a new MSA using an O365 email address (see https://blogs.technet.microsoft.com/enterprisemobility/2016/09/15/cleaning-up-the-azure-ad-and-microsoft-account-overlap/).
Also, it is very easy to change the primary email address for an MSA , hence effectively removing the work email address from the MSA (see https://www.howtogeek.com/277170/how-to-change-the-primary-email-address-for-your-microsoft-account/).
Thank you! I was aware of the cleaning stuff in Azure AD ;-) ...remember I was commenting on this when it was disclosed by Microsoft. To me, there is a room for improvement when inviting external users to Office 365 so if you are inviting a user that is using same e-mail as a personal account and as a professional one, the invitation process where able to detect this and allow to choose the account type ;-)...just my 2 cents
Yes, now I remember that you already referenced the MS announcement... :-)
Anyway that info could be useful to someone other reading this thread.
About the choice between the personal account and the professional one when receiving an invite, AFAIK it is already so! ;-)
- I meant at the moment you are adding the external user in the Group :-) so when asked to Sign In he/she does not have to choose the account type
Ah... OK!
