To adjust the column width, follow these steps:

  • Click Start and click Run.
  • In the Open box, type regedit, and then click OK.
  • In the Registry Editor navigate to the following key:
  • HKEY_CURRENT_USER\Software\Microsoft\Exchange\Client\Options
  • With the Options subkey selected, on the Edit menu, point to New, and then click DWORD Value.
  • For the name, type AddressBookColWidth, and then press ENTER.
  • Double-click AddressBookColWidth, and in the Value data box, type the width you want. You may have to change this setting until you arrive at the number that best suits your needs. A recommended starting point is 79.
  • Click OK to save your entry.

Leave the Registry Editor open and switch to Outlook. Open the Address Book and see if the column width is acceptable.
If not, close the Address Book, leave Outlook running, and switch back to the Registry Editor to adjust the DWORD Value until you arrive at the column width you want.
As you make adjustments all column widths in the Address Book are adjusted. If the value is too large, such as 1025, you may notice some of the right-most columns disappear.

The complete mailbox added to the Folder list can be removed from Outlook. This can be done by navigating in Outlook to: Tools > Email Accounts > Remove or display existing accounts > Next Here, select Zarafa client and click Change.... A new window will be opened. Click the tab Advanced, select the name of the user of which the mailbox should be removed and click the Delete button. When you select OK and Finish you will leave the window and Outlook will be available again.

If after the creation of the user profiles in Outlook the public store is created, this store will not be visible to the users whose Outlook profile have been previously created. Without access to the public store, the freebusy times will not be available either. The same problem can occur when migrating from old pst files, where the same profile is being used with Zarafa. The profile will reuse the old data which do not contain the public store. In order to make the freebusy data available again, new profiles should be created.

The Zarafa Migration Tool performs a migration by opening each user’s store in the data source (exchange.pst or Scalix db), travesing over the MAPI folder structure migrating each message and folder. This means that all data from the data source will be migrated, including mail, attachments, appointments, tasks, contacts etc. The Zarafa Migration Tool will also check if the message/folder already exists at the destination (a Zarafa Server or a .pst file) to avoid duplicates. The tool will not create users on the Zarafa Collaboration Platform, it assumes that the users to which the administrator wants to migrate data to already exist on the Zarafa Server.

Problem: I just updated Zarafa to a new version and now I get reminders that I didn't ask for.

Solution: Outlook has a table for all reminders.This table will be completed during the update with reminder information for all possible calendar items with a reminder. Old reminders will be (re-)activated and are hard to remove.

To remove these old reminders, close Outlook and perform the following steps: Click on Start > Run and enter: outlook.exe /cleanreminders. Then click OK to start Outlook. During start-up, Outlook will clean the reminder table.

If reminders do not work at all after this command, you will need to close Outlook again, and perform the following steps:Click on Start > Run and enter: outlook.exe /resetfolders. Then, click OK to start Outlook. After this step, your reminders should work as expected.
