Client: Outlook 2003/WIn XP
Server: Exchange 2010/Win Srv 2008 R2

I cannot add an appointment in Outlook offline mode (no internet connection - ie in the airplane) When I try to save appointment I am getting an error "the connection to the microsoft exchange server is unavailable. Outlook must be online or connected to complete this action"

FYI, the endryption between the client and server is checked in the outlook settings.

Please advise,

Derek

Try to create a new outlook profile and try that.  Cached mode seems like it might be messing up but should allow you to edit your own calendar.

Can youread your emails while you are offilne? It looks like you have not configured an offline folder.

Go to your account properties and make sure that Cached mode is enabled

jramsier,

This is a new exchnage 2010, I have created new profile already, also deleted OST file and recreated from scratch.

Akhater,

The cache mode is enabled I am able to view emails, calendar, contacts but cannot save new ones.

I belive that I must turn off forcing mandatory encryption between the clients and exchange server. I cann do that on the exchange srv 2010 - shell. But I need a confirmation because I do not have access to my client's laptop and do not want to keep guesing.

I have seen this work with encryption.  You obviously have outlook SP3 installed since it is working with 2010 exchange right?  Encryption needs to be enabled on the users client too so you may need to change that if you remove it.  Is this happening to multiple people or just one?

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Do you think if I remove forcing encryption from the exchange server, woul I have to disable encryption on all clients? It is important I do not want to affect all clients which have an encrytion turned on


------

To disable the required encryption between Outlook and Exchange, follow these steps:

On the server that is running Exchange 2010, run the following command in the Exchange Management Shell:

Set-RpcClientAccess –Server Exchange_server_name –EncryptionRequired $False

Note The Exchange_server_name placeholder represents the name of an Exchange Server 2010-based server that has the Client Access Server role.

You must run this cmdlet for all Exchange 2010 Client Access servers.


Rerun this command for each Exchange 2010-based server that has the Client Access Server role.


After your Outlook clients are updated with the setting to enable encrypted RPC communication with Exchange (see steps provided below), you can re-enable the RPC encryption requirement on your Exchange 2010 servers that have the Client Access Server role.

To re-enable the RPC encryption requirement on your Exchange 2010-based servers that have the Client Access Server role, run the following command in the Exchange Management Shell:
Set-RpcClientAccess –Server Exchange_server_name –EncryptionRequired $True

Note The Exchange_server_name placeholder represents the name of an Exchange 2010-based server that has the Client Access Server role.

This cmdlet must be run for all Exchange 2010 Client Access servers.
