Hi There

I have recently migrated from exchange 2010 to exchange 2013

When the users try to create a new email and click the TO: button and it defaults to the GAL when they try to select contacts it displays an error message which i have attached

If the user goes direct to the contacts folder and sends and email to a specific contact it will work that way

I have tried to remove the mapi address book but am unable to remove this has now become an urgent issue for the client

Setup is

DC
Exchange
RDS Servers

Any help is greatly appreciated

Hello
Check this i had a similiar problem on a migration once, check these settings...also can you access the GAL via OWA?..

Connect to the Exchange admin center > recipients > mailboxes > locate your user > Edit > Ensure "Hide From Exchange Address Lists" is NOT ticked.

Connect to the Exchange admin center > organization > address lists > Default Global Address List > Edit > Preview recipients in the global address list includes... > Locate the user.

Force the OAB to update:
via powershell:
get-offlineaddressbook | update-offlineaddressbook

Hi There

Thanks for your response

Unfortunately that hasn't worked, i did check the generation servers of the GAL & OAB and they are the correct server

Have no issues when accessing the GAL but when any of the users try to access their outlook address book or try to view contacts from the to line in outlook 2016 they get the same error displayed

I haven't decommissioned the Exchange 2010 server yet but have disabled the services for Exchange

This issue is a system wide problem unfortunately not just a couple of users

Thanks

I tried that but in reverse as they are using remote desktop services, if i set the outlook client to use cached exchange mode it will display contacts without any issues but if i set the outlook client to online mode i get the error of being unable to access the contacts

Have deleted and recreated mail profiles which doesnt change unfortunately what i have found is that if the profile is set to cached mode then everything works without issue but if it is set to online mode contacts are unavailable as this is being used in an RDS environment the preferred solution is to use online mode as they have limited storage space available, have also confirmed OAB generation server and it is set to the correct server which is the new Exchange 2013 box thanks

An update for this is we have found what is causing the problem, It was the Eset V6 File Security Addon for Outlook that was causing the problem, It is currently logged with Eset to find out why.
