Synchronising mobile contact lists with M365

[Ditto]

My company has just issued all mobile phone users with a new android phone. They are now allegedly all MDM (I assume via InTune).

 

Our IT support company have spent at lot of hours (possibly at our expense) trying to put together a Power Automate or PowerShell solution to migrate the GAL to the phones contact list. Sounds a bit mad to me. I suspect there is no good reason for the whole GAL to be migrated, but there would be a list (or more) that each phone user. Probably there should be one common address book for the phone users and it may contain details of contacts outside our domain.

 

So, some questions and advice please.

 

i) Given all phone users will have an M365 account, do we even need to synch to the phones contact list

ii) If we did accept GAL synching, how would that best be achieved

iii) If we had a dedicated address list, how would that best be setup and synched.

iv) If an individual wanted to keep contacts beyond the list, especially for contacts outside of the domain, how is that best managed?

not much help but wouldn't they be using some VOIP client on the phone so contacts come from that

Mostly phone use would where no internet connection is available so relying on telephone cell network. When staff are within the office or have internet capability, they'd use Teams Voice. This challenge is specifically for when they are out and about and need to make calls.
