This error might be caused by changing this setting.

When having this error in OWA, ECP or Outlook:

You can fix this by setting the correct time zone in Outlook (you cannot change it through ECP – you need Outlook):

File > Options > Calendar > Time Zone section

Label: YourCity (e.g. Brussels) Time Zone: YourTimeZone (e.g. UTC+1 Brussels).

Be sure to pick the correct time zone and fill in a label.

In case you started Outlook with say, a Dutch localization, folders like “Inbox” are named “Postvak In”. Idem dito for replies on read receipts (Gelezen ipv Read), or Meeting Requests.

I haven’t found an option to change this within Outlook, but using OWA, you can change the option and rename it.

For example, using the ECP from my company:

Restart Outlook – the problem should be fixed.

I noticed my “Offline Address Book” was no longer automatically updating.

Running “get-offlineaddressbook |fl” in the EMS showed it last updated somewhere 16th November 2010.

Trying to manually update it through EMC (“Organizational Configuration > Mailbox > Offline Address Book > right click Default Offline Address Book > click update”) it gave me this error:

 Two possible reasons for the failure are that the System Attendant Service is not running or
 you do not have permission to perform this operation. Error message :

I googled for quite a while trying to find a fix, but nothing useful could be found.
