The Intra2net Groupware Client cannot be used with a Microsoft Exchange data file on the same profile. However, it is possible to work together in different Outlook profiles on the same PC without any problems.

Limitations on handling invitations when using the account on multiple devices or with shares.

Incoming invitation emails, appointments created from them and self-created appointments with invitations should only be accepted or edited with the Groupware Client and only on one device. Otherwise the appointment may be duplicated, incorrect messages to the organizer or incorrect display of the invitation status may occur.

Changed attendees of a recurring element in a recurring appointment

Full-day appointments series that extend over several full days

Journal feature

Linking groupware items with each other (e.g. between a contact and an appointment)

Attaching files to groupware objects (not to emails). Files attached to groupware objects are not written to the server and are therefore not visible to other users or devices. If the object is modified by another device or user, the attachment is removed. They are also not included in the backup.

Task assignments received by email cannot be processed

Email tags for tracking and tracing with dates are not written to the server and are therefore not visible to other users or devices. It is also not included in the backup. Therefore, use the method described in Section 25.4, „Email Reminders and Tracking“ instead of the tag for tracking.

If an email is both answered and forwarded, only one of the two is displayed as a status in Outlook.

It is not possible to rename shared folders of other users. Only the owner can rename folders.

No automatic execution of client-side sort rules in Outlook. Instead, use server-side sort rules as described in Section 24.3, „Editing Server-Side Settings“.

Outlook's "undo" function is not supported.

Automatic response to read receipts requested by the sender of an email (Message Disposition Notification (MDN)). See Section 25.5, „Read receipts“.

The Groupware Client is designed for up to 500 folders, 50,000 objects per folder and email and groupware data of up to 10 GB (accounts connected in a data file, measured on the server, e.g. via the menu "Information > Statistics > Users").

If these values are exceeded, disruptions may occur. These include, but are not limited to, delays in responding to user input, delays in synchronizing changes, and program crashes.

The fixed maximum size of the data file is 50 GB (for Outlook 2007: 20 GB). The data file contains all linked folders, regardless of whether they are own folders or shared ones of other users. When the maximum size is reached, the data file is irreparably damaged and all data must be freshly synchronized in from the server.

Using the option "Only headers" (see Section 25.1, „Retrieve Emails Completely or Only Headers“) you can save space in the data file.

In the quick search function of Outlook (but not in the advanced search), while the search is running, search hits appear in random order first. Once the search is complete, it can be sorted. In addition, deleted items cannot be excluded from the quick search.

Unable to use the "Notifications" folder name at the top level of the data file.

Folder names that differ only by upper and lower case from other folder names on the same level as well as folder names that start or end with spaces are not supported. This is a limitation of Outlook.
