Apple iPhone Text responses go to wrong country code

A user wrote: Recently I went to Portugal and when I was there I bought a sim card and put it in my iPhone 11 Pro, with my primary e-sim still in it. When I got home to Australia, I deactivated the Portugal sim-card, deleted it and took the sim card out. Now when someone call me I respond with text, my iPhone changes the calling numbers country code to +31. I had the same problem. Despite turning "Dial assist" on/off, checking Country, Language and all the suggested stuff it did not work for me. What I did at the end was deleting country prefix from contact numbers --> Save --> Added country prefix again . It works now.

Reason: [{LED=250 2.1.5 RESOLVER.GRP.Expanded; distribution list expanded};{MSG=};{FQDN=};{IP=};{LRT=}]

 If you got this error checking the mail flow for a distribution group, it means the distribution group is closed and only internal senders can send e-mail to this group. When outside user sends e-mail to this group you get  Reason: [{LED=250 2.1.5 RESOLVER.GRP.Expanded; distribution list expanded};{MSG=};{FQDN=};{IP=};{LRT=}] Set Delivery for this group to internal and external users and your problem will be solved. 

Check if you have users with both mailboxes on-prem and online

An Exchange Online license was applied to the user before the Exchange GUID got synchronized from on-premises Active Directory. For synchronized accounts, having the Exchange GUID synchronized from on-premises is used to tell Exchange Online that the mailbox hasn’t been migrated yet, and is what allows customers to pre-license accounts prior to migration.  From:  My user has a mailbox both on-premises and in Exchange Online. So, in my case many times we get into situation where license is applied before Exchange GUID is synchronized to O365. I am using this script to check whether user has two mailboxes. Script closes Exchange session BEFORE it opens connection to Exchange Online as both use same commands. You can use Get-Mailbox both on-prem and Online, therefore it is crucial to close connection before you open other. # DISCLAIMER: # This code is provided "as is" without warranty of any kind, either express or implied, including but not limited to the implied warranties of
