Outlook 365 email file attachments are not being received by recipients on an intermittent basis. When I check sent mail, there is paperclip indicator that attachment is there, but there is no attachment when I open the sent email! Settings for sending mail and format is set at HTML as it should be. All updates have been installed. I also ran a repair on Office 365 on my laptop, both quick and online. Our entire company is on Windows 7 Pro OS. All of us use Office 365. So far, 3 of us have had this issue. Please let us know what else we can do to trouble shoot. Clients are not getting attachments. We have to resend. The resend seems to work, but we do need to resolve.
This problem is very recent, happened this week. Thank you.
