SMTP account and Office365 send limits....

[DrewW]

So we are a Health care company and we need to make sure that when some messages go to vendors that those messages use encryption.  We have Office365 and when we put certain words in the subject the mail system takes care of this for us.  For this reason we added our own SMTP account to the system and disabled the default.  Also do to other reasons we cannot use it as a simple relay and have use authentication to send message.

What we have found is Office365 has some hard limits on total recipients for a 24 hour period and we were told that there was no way to alter this.

Is there anyone out there that has a similar setup and found an easy way around this?

Right now I'm looking at having to setup two or more accounts and alternate between them in an automated fashion.

Did you ever figure out how to address this issue?  We are facing the exact same problem and so far the only solution I can come up with is "send less email."  We're still within our limits now (the limit for our O365 license is 10000 recipients/day), but within a few years we will easily run into a wall.

We setup several outbound email accounts for SMTP and then setup several fields to count the recipients and track the account that was used.  When we started reaching the 10k limit for the one users a job would automatically disable the one account and enable the other.

But about 3 months after we set this up they decided we did not need this so it was all disabled.
