Is it possible to have multiple exchange accounts with cached mode individually set off for group mailboxes?

Hi,

From the description, you want to set Exchange account with cached Exchange mode for some users in a user group and the rest of users set to online Exchange mode, correct?

If this is the case, I think you may consider using Security Filtering. Using security filtering, you can specify that only certain security principals within a container where the GPO is linked apply the GPO. Security group filtering determines whether the GPO as a whole applies to groups, users, or computers; it cannot be used selectively on different settings within a GPO. See:

If you need further assistance regarding Security Filtering, I'd recommend you post in the Group Policy forum:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
