Troubles uploading documents to email

Troubles uploading documents to email

Today I am trying to attach documents to emails and, although ZOHO shows the document is trying to upload, it never does.  I have tried multiple emails with  different docuements.  I  have also tried sending emails out of Zoho Mail instead of CRM and have the same trouble  attaching documents.  Is this  a problem that ZOHO is experiencing?  I have rebooted several times as well.  If anyone can assist I would appreciate it.
