Configuring Outlook to enable the processing of items with many attachments or many recipients
You must install a supported version of Outlook on the Discovery Accelerator server so that client users can export Exchange Server items in PST format and download the original versions of the items.
By default, Outlook does not allow any items that have more than 2048 attachments or 2048 recipients to be opened. To avoid problems when client users try to export or download any items that have a larger number of attachments or recipients, set the registry values AttachmentMax and RecipientMax on the Discovery Accelerator server.
To configure Outlook to enable the processing of items with many attachments or many recipients
- On the Discovery Accelerator server, start the Registry Editor.
- Where version is 15.0 for Outlook 2013 SP1, 16.0 for Outlook 2016, or 19.0 for Outlook 2019.
Do one of the following:
If you do not use policies, locate and then click the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\Office\version\Outlook\Options\Mail
If you use policies, locate and then click the following registry subkey:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\version\Outlook\Options\Mail
- On the Edit menu, point to New, and then click DWORD Value.
- Type AttachmentMax, and then press Enter.
- Right-click AttachmentMax, and then click Modify.
- In the Value data box, type the required value, and then click OK.
The recommended value is FFFFFFFF in hexadecimal.
- Repeat steps 3 through 6 to add the RecipientMax registry entry.
- Exit the Registry Editor.
