Authentification failed - The input is not a valid Base-64 string as it contains a non-base 64 character....". Help!

I am receiving errors when sending emails that read “The input is not a valid Base-64 string as it contains a non-base 64 character…”. I have had this for the past couple of days now and it requires me to go into Diagnostics to fix the issue. Help!

Hi Thom,
could you take a screenshot of this error message? Also, after the error message pops up, check the third tab in the same window titled ‘Log’ and copy its content here, please.

Regards,
Olivia

Olivia, here is the information you requested. I am still having the issue as described. Thanks.

Hi Thom,
seems there is a problem with your SMTP server authentication.
Could you please turn on SMTP logging for your affected account in Tools>Settings>Advanced?
Restart eM Client after this and when this error pops up again, go to the advanced setting again and click Send logs.
Change the recipient of the message to rust@emclient.com and add link to this forum topic in the message body so I can get back to you.

Regards,
Olivia

I get the same error and had to go back to Outlook
