Hello DB O365,
Thank you for reaching out!
I understand that you have a query on syncing the GAL to the outlook mobile app. It is not possible to sync the entire GAL to your mobile device, but you can search for contacts in the GAL using the Outlook app for iOS and Android by typing their name in the “To” field when composing an email. There is no dedicated M365 Mobile contacts app that would allow users to have easy access to the current GAL. I do understand your need for this, and we will surely raise your concerns with our product team.
In the meantime, I did find similar post in the feedback forum Global adress list syncronization with phone contacts · Community (microsoft.com). You can upvote or add a comment to push for this if it is in line with your requirement. Otherwise, you can as well raise a new entry in the forum on link Outlook · Community (microsoft.com). Many features of our current products are designed and upgraded based on customers’ feedback.
Thank you for your kind understanding.
Best Regards,
Ashraf.
Thanks for looking here - however "you can search for contacts in the GAL using the Outlook app for iOS and Android by typing their name in the “To” field when composing an email" - You can't any more; the directory search has been modified in the mobile app's, such that it only finds the e-mail addresses of people you have previously contected from the GAL in the desktop app... so only works where you've previously sent or recieved a message to that person eg where the information is already in your outlook contacts by other means / cached there. There are 3 names in my GAL that start with the letters CM - I can find all 3 on my desk PC (Outlook app or Webmail) and only find the 1 of them I have previously contacted in the mobile app.
I will do the up vote on the project - as that might eventually put this business critical look up back in to the mobile e-mail where it's needed.
Regards
Dave
