Set it? :-). Easier said than done..
After iterating through my Users i maybe even find why my fresh personal Mailbox is not accessible with Outlook.
gromi:~ # for u in `grom_users`;do grommunio-admin exmdb $u store get DISPLAYTYPEEX ; done
displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0

displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0
displaytypeex 0
(No properties)
Does an grommunio-admin exmdb your@mailbox.tld store set DISPLAYTYPEEX=0
help? Not that it fixed my current problem :-).
And i just guess that this would be the correct exmdb-value...
