Guest users do not receive Office Group conversations
'OtherMails' is an attribute managed by Azure AD afaik, you cannot change it via the Exchange cmdlets. You should be able to change it via Set-MsolUser/Set-AzureADUser or the Graph API directly, but I'm not sure if such changes later flow to ExO. They should I suppose, so give it a try.

VasilMichev thank you for your answer.
'Other Mail' is not the same as 'OtherMails' property.
In my case 'OtherMails' property is set correctly for all 'problematic' users (it contains the user's email address).
When I'm comparing properties for guest user who gets group conversation with guest user who does not, only difference is in 'Other Mail' property (which I get by executing cmdlet: Get-MailUser -Resultsize unlimited| ? {$_.externalemailaddress -match "[guest user email address here"} | fl).
'Other Mail' property is empty for the user who doesn't get group conversations.
In some cases recreating guest users (deleting user and inviting again) works. But I have a few cases for which it doesn't work and even after recreating they still don't get group conversations and the 'Other Mail' property is empty.
