Questions[outlook-2016](server)

We're running Outlook 2016 on Exchange Server 2013. We are able to reply to incoming emails to that (shared accounts') email address, but when we do it's being put into the user's account's own Sent Items.

We want the replies to go into the shared account's sent items instead so that the other users sharing the account can reference the information.

The topic at replies or forwards from shared mailbox going into wrong sent items is pretty much the same issue, although we're using Office 2016 (and Exchange 2013 as stated above).

Also, we need to resolve this without editing everyone's registry.

Is there a way to do this, or am I chasing a dead end? I can't seem to find ANY information on this at all. This SHOULD just be a simple setting, but the solution evades me.

Under account settings Outlook2016.
One has the option mail to keep offline in the gui, to cache Email.

Problem: For unknown reasons it stays at 1 month or all time.
One should be able to alter the period by policy or registry:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\xx.0\Outlook\Cached Mode  
 xx.0 =   
  Outlook 2016 is 16.0  
  Outlook 2013 is 15.0  
  Outlook 2010 is 14.0  
  Outlook 2007 is 12.0  
  Outlook 2003 is 11.0  
  
Create a DWORD value of SyncWindowSetting, and then set the desired value:  
0 = All (whole mailbox)  
1 = 1 month of email items  
3 = 3 months of email items  
6 = 6 months of email items  
12 = 1 year of email items  
24 = 2 years of email items  
36 = 3 years of email items (Outlook 2016 only)  
60 = 5 years of email items (Outlook 2016 only)  

I even added the Dword value Enable and set it to 1.

I need to have syncWindowSetting to 12, to keep one year of email cached in the OST, however outlook seams to completely ignore these values, and sticks to one month only or all
Any ideas to get it working for only 1 year are welcome

a registry export of my outlook settings is below:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Cached Mode]
"SyncWindowSetting"=dword:0000000c
"SyncWindowSettingDays"=dword:00000000
"Enable"=dword:00000001

However whatever i do inside outlook 2016 it stays at 1 month.
As for registry permissions, the user and system can read above entries.

Our organization sets up "shared" mailboxes by just creating a regular mailbox and then giving people Full Access in the ecp/exchange admin. It then automaps to their Outlook client. But we are running into the bug where emails sent to that address marked as private, will be invisible. Users can see the count ("Inbox 6"), but not the actual email in Outlook client (only in OWA). The only "fixes" I can find involve a system using Delegate settings. We do not do delegates. No one in our company is a listed delegate nor are these "shared" mailboxes even attached to a client as a standalone where Delegate settings could be managed. Any other resolutions for this?

Working in a 2019 Domain Active Directory, running 2019 Exchange Server, using Office Professional Plus 2016.

Adding a new account to Outlook, connect to exchange using autodiscover, the process goes smooth open the mailbox, populate folders and show the content. After a few minutes, 'need password' and a (looks like a web request) for a password. Just clicking 'Type Exchange Password and Continue' on the 'send/receive' bar, reconnect and... smooth sailing again.

Assuming domain is VALID and user is USER. Checking the security log on Exchange Server, I can see the initial connections is for VALID\USER but, the next one, that fails, is for EXCHANGE\USER. Our server name is EXCHANGE. Why trying to use the wrong domain? It also try USER@VALID... without sending the domain, that also fail.

Tests:

In Outlook-2016, create a new profile, add the domain account: same result. I should note that Outlook did not ask for username\password. The computer I'm using is not join to DOMAIN.

Hints:
I test the connection using the TestConnectivity tool results show ok, with no mention to DOMAIN as domain.

I've been trying to troubleshoot an error message on our Server 2008 RDS farm for about 3 weeks now and I'm getting nowhere. Randomly Outlook 2016 crashes and freezes. Sometimes it recovers and the user can carry on with their work and other times it bombs and completely throws the user out of Outlook. From what I can see it creates an event log id of 1000. Application error 1000

The servers are completely updated, I've reinstalled office, run registry cleaners. The only thing I haven't done is to remove office, run sfc /scan and reinstall office. The error is common with all 6 of the RDS servers so I'm reluctant to do that right now.
I'm In the middle of building our new RDS environment but it's been put on hold, for obvious reasons. Very frustrating! Any help is appreciated.
