Special Characters in Folder Names

Topic Last Modified: 2006-12-06

When you create a folder in the Exchange store programmatically, there are no character restrictions on the folder name. Special characters, such as "*" or "?", are allowed in folder names, but their use is not recommended because they may be displayed incorrectly in Microsoft® Windows® Explorer. When you create a folder through Windows Explorer, however, the following special characters are not allowed in folder names:

/ \ * ? < > |

When you create a folder in the Exchange store using Microsoft Outlook® Web Access, there are some restrictions on using special characters in the folder name. The following special characters in a folder name will cause an error to be generated:

[ ] / \ & ~ ? * | < > " ; : +

Outlook Web Access will display any pre-existing folders with names that contain any of the special characters above.
