FAQs: Public ShareFolder for Microsoft Outlook


4. Support / FAQ No. 03

No.03: Does Public ShareFolder also work with different Outlook® versions (Outlook® 98 - Outlook® 2002 and Outlook® 2003) in one network?


In principle, yes, but also Microsoft®recommends not to use Outlook 2003 and higher with older Outlook versions in a network. If you open an “old” PST file (Outlook 98 — Outlook 2002 PST file) with Outlook 2003 and you create some items and after this, you open this PST file with Outlook 98 — Outlook 2002 you could lost this new items or some fields in it.

In a pure Outlook 98 — Outlook 2002 and a pure Outlook 2003 and higher groupware network there are no compatibility problems, only with Outlook 2003 and higher together with "older" versions.

Two examples: The field "Notes" in a contact and also the "body text" in the calendar of older versions cannot be concatenated between Outlook 2003 (and higher) and Outlook 98 — Outlook 2002. With most fields however there are no problems with the common use in a groupware, but with some.

We prefer to use the "oldest" Microsoft® Outlook® Version as "server" and the newest versions on the clients.

Not supported Outlook versions:

  • Outlook® 2010 / 2013x64 (64-Bit version). 32-Bit Version are supportet.
  • Outlook® 2010 / 2013 Click-to-Run versions

Microsoft recommends to install Outlook® 2010/2013 x86 (32-bit) by default:

"The 32-bit version of Office 2010/2013 is the recommended option for most users, because it prevents potential compatibility issues with other 32-bit applications, specifically third-party add-ins that are available only for 32-bit operating systems."

You find more information on:

The Outlook® 2010/2013 Click-to-Run version does not support the COM interface "Extended MAPI", therefore Public ShareFolder can not access Outlook: http://support.microsoft.com/kb/981242
