I have a user with the exact same error occurring.

AzureAD user with M365 exchange

Win10 20H2 (19042.928)

Outlook Click-to-run (v2008 build 13127.21506)

User can send and receive emails

User can reply to emails

Some emails can be forwarded, some not.

Those emails that fail to forward return the error below.

About to test issue on web client but believe it will work based on seeing this for another user a few months back.

Will rebuild laptop to rule out issues with profile and outlook client.

As this is occurring across multiple customers I think Microsoft should review further.

@JT you are certainly not alone in seeing this fault

Issue seems to likely be local user profile or outlook app

Hi guys,
Anyone found a solution to this issue? I'm having a few users with the same problem, only when they try to forward an email with a PDF attached. The email isn't processed at all on mimecast, and I cannot see it on Exchange as well.

Have you been able to find any workaround or solution?

I never found a fix for this, only thing that worked was to have the user clear the email address they were sending to out of their outlook cache (is it called Nicknames still?). Then they need to manually type the full address for the recipient and send again. Have probably used this workaround 3 times in the last 6 months and it has worked. I presume something is corrupting in that outlook cache
