hi acumenx,

yes, possible. on server side, admin need first check if “share contacts folder“ in exchange admin center > organization > sharing  > individual sharing > default sharing policy enabled or checked. can refer screenshot , step article change default sharing policy, , apply configuration on both exchange organizations.

let define domain-a , domain-b 2 different exchange users.

i understand can share contact folder others in outlook windows (domain-a), , have opened outlook sharing invitation in outlook mac (domain-b). let me know if misunderstood.

regarding “the mac version won't let me add exchange email address windows installation when try add permissions on organize tab”(domain-b), please provide more details or screenshots understand scenario. if referring share exchange folder in outlook mac, , under people tab choose “add user” option on sharing permission option of contacts (domain-b), not show external address (domain-a) add permission in folder, , show ”add” button screenshot greyed out.

it not feasible share external contacts in outlook mac. thank understanding. workaround, can manually send contact information via vcard, import vcard outlook contacts on outlook windows.

we suggest submit feedback related team via link: (https://outlook.uservoice.com/forums/293343-outlook-for-mac) . many features have been designed or upgraded based on customers' valuable advice.  

if scenario misunderstood, please provide following information further troubleshoot:

1.) the detailed outlook mac version, like 15.29 (170104). , mac os version.

2.) screenshot regarding “the mac version won't let me add exchange email address”

3.) issue occur specific user or users in organization?

4.) check if issue occurs on mac machine.

looking forward updates.

best regards,

ruel
